      <title>最后的博客</title>
      <link href="/posts/last-blog/"/>
      <url>/posts/last-blog/</url>
      
        <content type="html"><![CDATA[<p>在写这篇文章之前，我折腾了一下午的npm。改了依赖，扔了失修已久的<code>multilingual feed</code>，为了解决一个错误听ChatGPT的话改了tranquilpeak主题一通，最后告诉我只要把<code>strip-indent</code>的版本改回3.0.0就行了。现在这个时间点再运行<code>npm audit</code>，应该是0漏洞了。</p><p>这个博客从设立起到现在也快6个年头了。所以我想回忆一下这些年是怎么一路折腾来的。然后再谈谈这个博客的未来。</p><h2 id="心路旅程">心路旅程</h2><h3 id="域名">域名</h3><p>域名的问题，当时noir.moe和noire.moe都不知被谁注册了，所以一开始是noirina.moe，反正Noirina也是Noire。后来追求短，就变成了现在的nir.moe。现在noir.moe没有人注册，欢迎去买，noire.moe不可用，但是也不知道注册的人拿来在干啥——不用不如捐给我。</p><p>除了这个之外，<a href="http://xn--4gqsgvnk6gey3a8kfg8kdmct10k1ea910e.me">我还注册过一段时间什么.me</a>，大概是用的本名，解析到Blogger去。反正那个Blogger也没写什么东西，就没续费了。</p><p>我忘了，很久很久以前，其实是nomamama.top和nomamama.xyz。Nomamama是我名字的一个anagram（之后才发现不仅把w改成了m，还把一个u改成了a）结合Segagaga得来的。现在用的Noirgif是另一个anagram，这个是先弄成日语罗马字然后再变来的。跑题了。在西部数码注册的域名，虽然很便宜（记得年费是个位数）但是后来要求备案，不备案就不给解析，于是这个域名就送他们了。</p><h3 id="服务器">服务器</h3><p>一开始是在12美元一年的Ethernet Servers，搞个Nginx挂着（首要用途还是开VPN），然后是HostMyBytes。</p><p>这个博客的图片基本是传在Cloudinary上的。我需要先上传到那边，拿到URL再贴到这边。这大概是用VPS时候留下来的了。现在想想，其实图片也可以直接推到GitHub上。</p><p>用VPS的时候还想着用Cloudflare怎么加速——结果发现一用VPN就不好使了。但是现在就没有必要了，name server还是用的Cloudflare，也是当时留下来的。</p><p>在2018年底的时候，我同时也部署到VPS和Github Pages上了（见<a href="/posts/github-pages">如何被 GitHub Pages 蹬鼻子上脸</a>。其实单用Github Pages也可以——访问<a href="noirgif.github.io">noirgif.github.io</a>就是走的pages，但是我闲得慌，为了一点现在已经没用的功能，而搞了Netlify。</p><p>HostMyBytes在19年4月被Alpharacks收购，我在那个时候改用CircleCI跑Hexo，然后CircleCI部署到专用的分支。没用Travis CI的原因，印象里是因为它的镜像太旧了还是机子太破了，还是两者皆有？当时也没人教我，只好自己试着搞来搞去，搞成现在这个模样。</p><p>6月份那个VPS连不上，随后Alpharacks倒闭的消息传来，干脆就不要自己搭的Nginx，只推到Github上了事。从此这个博客只有域名是要钱的了，我觉得这是这个博客的顶峰。</p><p>半年后有了Github Actions。求你下次早点来。</p><h2 id="Hexo">Hexo</h2><p>在用Hexo之前我实在想不起来用的什么。大概是没有吧。用Hexo的起点大概是周围的人很多当时在用Hexo。印象很深的三个：</p><ol><li><a href="https://xuanwo.io">老涡的博客</a>：后来改用了Hugo。</li><li><a href="https://blog.skk.moe/">苏卡卡的博客</a>：不仅还在用，还自己折腾了很多，学不来。</li><li>没有第三个了。<a href="https://blog.yoitsu.moe">老肯</a>和<a href="https://farseerfc.me/">老fc</a>用的都是Pelican。</li></ol><p>喜欢的地方：主题很花哨。当时想着搞很多花哨东西，所以用了这个主题。现在没这个想法了。</p><p>有好有坏的地方：写作体验。用自己想用的编辑器，写Markdown固然简单，但是我有一个一直梦寐以求的功能：把图片拖进来，就能帮你上传到CDN，然后在博客里给你一个链接。我在Piazza用这个的时候就想着博客能不能有一个。Notion也会把文件上传到S3，不过Notion的数据可能都在S3。Hexo有一个Cloudinary插件，但是做的是你写一个tag，帮你插入Cloudinary上的图片，这种画蛇添足的事情。</p><p>头疼的地方：NodeJS加持的Hexo有很多插件，容易发生有的包没人维护了，这个没人维护的包的依赖有漏洞这种深奥的事情。按照这个部署的流程来说我是不需要管他们的？不是很清楚。但是想本地看一看效果的时候就很麻烦。今天我为此把multilingual feed删掉了。从此这个博客更新不分语言了：明天是英语，后天是日语。本博客虽然用各种语言写的，但是对多语言的支持闻者落泪。</p><p>我也不会折腾主题。把Hymmnos字体加进来（记得提醒我玩魔塔大陆3），被Katex折腾折腾，大概就是我力所能及的范围了。曾经有的、现在已经不工作了的飘雪的代码，其实是从Winter Plus的网站那里<s>偷</s>借过来的。请不要告诉North Plus我借了代码，也不要告诉上面的人我上过Soul Plus。</p><h2 id="总结">总结</h2><p>这大概会是我最后一次折腾这个博客了。下次再告诉我有漏洞，我会换到Hatenablog。届时大概会搞一个像R18网站一样的跳转选项，或者在主页里加一个banner。（最后一次折腾？）</p><p>最近玩蔚蓝档案，给我很深的感触，就是我经常被活动和人物迷惑了双眼，本来我最优先的momotalk却很少打开。</p><p>折腾博客，虽然给我带来很多收获，但是我感觉我渐渐离开了本博客随便写写东西的初衷。而这个初衷是我想继续贯彻的。所以我想以此为戒，也是纪念。</p><blockquote><p>Plus je écris les blogs, mieux j’aime les papier.</p><p>我写的博客越多，我就越喜欢纸。</p></blockquote><h2 id="附记：一点题外话">附记：一点题外话</h2><p>虽然游戏堆积成山（蔚蓝档案只是其中一个原因），但是最近有在打天使骚骚的 Demo。因为游戏堆积成山，所以还没有决定要买。</p><div class="figure " style="width:;"><a class="fancybox" href="/assets/image/tenshisouzou-3-30-2023-8-25-40.png" title="说这句台词的时候天使的表情就像万花筒一样" data-caption="说这句台词的时候天使的表情就像万花筒一样" data-fancybox="default"><img class="fig-img" src="/assets/image/tenshisouzou-3-30-2023-8-25-40.png" alt="说这句台词的时候天使的表情就像万花筒一样"></a><span class="caption">说这句台词的时候天使的表情就像万花筒一样</span></div><p>这篇博客开始写是晚上8点，现在已经是第二天了。昨天的日记也没写，Duolingo也没做，洗洗睡了。</p>]]></content>

      <title>Proposal of a New Type of Elevator that Uses Blockchain to Achieve High Availability</title>
      <link href="/posts/blockchain-elevator/"/>
      <url>/posts/blockchain-elevator/</url>
      
        <content type="html"><![CDATA[<h2 id="Introduction">Introduction</h2><p>As you may already know, the elevator in the computer sciences department has been broken since Friday and will remain unfixed throughout the weekend. Although we have a backup elevator, it gets overloaded even on a Saturday morning. When I went to grab a cup of coffee, someone else had already ridden it, so I had to take the stairs.</p><p>We strive to create systems with high availability. A loss of three days (averaging 0.9% throughout the year) is hardly acceptable. This brings us to today’s main theme:</p><p>We present a proposal for a new type of elevator that utilizes blockchain technology to achieve high availability.</p><p>The idea behind this proposal is to create an elevator system that never goes down. By using a decentralized blockchain network, the elevator system could potentially achieve 100% uptime, with no single point of failure.</p><h2 id="Design">Design</h2><p>The elevator’s control system would be connected to the blockchain network. Every time a passenger boards or exits the elevator, a new block would be added to the chain. The blocks would contain information about the elevator’s current position, direction, and speed. You can think of it as a transaction: validators (a new name for blockchain miners in this context) will include it in the chain. Once six blocks are validated on top of it, we will consider it confirmed, and the elevator will move toward the destination. The confirmation of the transaction on the Ethereum Mainnet takes approximately 84 seconds. However, faster confirmations can be achieved by using private chains.</p><p>Thanks to the decentralized nature of the system, the elevator will continue to function as long as most validators are online. Even if a hacker tries to tamper with the system, the blockchain’s consensus mechanism will ensure that the elevator’s history remains accurate and unalterable. If you take a two-hour coffee break on the sixth floor, everyone in the department will know about it.</p><p>In addition, the immutability of the blockchain guarantees that there will be no disputes over the operation of elevators, which can occur with traditional elevator systems. For instance, people often disagree on how long the doors should remain closed if no button is pressed, and it is often unclear whether the “close door” button accelerates the closing. With blockchains, these rules are enforced by the system, and there is no room for interpretation.</p><h2 id="Conclusion">Conclusion</h2><p>Elevators powered by blockchain technology have a lot of potential. We highly anticipate that they will replace the current broken elevator in the CS building.</p><p>Happy April Fool’s Day!</p>]]></content>

      <title>最近电影四连</title>
      <link href="/posts/2210-recent/"/>
      <url>/posts/2210-recent/</url>
      
        <content type="html"><![CDATA[<p>因为Notion的字体看起来很不爽（黑体宋体夹杂），就在word上写了。在word上用的是霞鹜文楷。想不起来名字的时候就会想起来原神的可莉，这个字体的原型是名叫可莉的字体。二来word也有所谓的focus mode，会隐去一切无用UI。windows更新以来也有了focus session。可以做到一种二重buff。在加上平时会开的focus assist，就可以聚焦到烧焦了！火，生命之火。燃烧，生命的意义。果然只有燃烧的时候，蜡烛才在证明自己的存在。SM？不SM。</p><p>闲话少叙。果然，最想分享的还是，最近无意之间连续看了三部meta电影。Meta电影只不过是我心里的说法，如果要说人话，那就是三部关于电影的电影。</p><p>第一部看的是《Nuovo Cinema Paradiso》（天堂电影院）。看的原因的话，果然还是《我想成为你的眼泪》（君の涙になりたい）这部小说。书中提到的是电影最后的片段，再者好像是名作，于是就看了。我也是按照书里的推荐，没有看3小时的版本（导剪版，反而越剪越长，真是疑惑），看的127分钟的原版。……是127分钟吧。讲的是一个人随电影成长的故事，然而电影没有伴随着人成长，而是默无声息地消失了。至于问题的场景——或者说问题的场景的剪辑——如果那些电影我都有看过就好了，我是这么想的。如果没有看过，就会像我现在这样，试图从干燥的海绵上硬挤出一两滴水。如果看过的话，就会像主人公那样，既失笑又怀念，笑着笑着不禁眼泪流下来吧。所以可能还是生错时代了。</p><p>第二部是《映画大好きポンポさん》（最爱电影的庞波小姐，或者是别的称呼）。讲的是围绕新电影制作，新人导演Gene Fini，新人女演员Natalie Woodward等人如何活跃的故事。一个特点，就是将电影制作，从一开始的剧本、选人，到最后的剪辑都有涉及。所以论meta程度，这部应该是最深的了。虽然Gene想看《天堂电影院》，但是Pompo小姐显然不是很有耐心看完，甚至暴言道，超过90分钟的电影都没意思。而这也是这部电影有意思的一个地方。因为涉及剧透，我就不想提及了，但是这种meta发言也是让我眼前一亮的地方。最近在看的《ユア・フォルマ》（Your Forma，中文不知道）（我讨厌word的地方：日语输入法切换 Alt+`，会调出听写）里，插图里有很多QR码，按文中的说法，是电子毒品的信息，不能直视，因为会脑内自动扫描。如果真的用手机扫了，其中一个QR码还会说“明明告诉你不要看了”。</p><p>第三部，其实不是第三部。是《Bullet Train》（子弹列车），大概1小时40分钟。听同学说的于是打算看，正好发现附近的AMC有上映，于是就去看了。说是附近，骑车也要40分钟。回想起来，还是不清楚这是好事还是坏事。去程是坐公交去的，这里的公交，前面有自行车架，可以放两辆车。因为去的时候是中午（中午的电影能打7折，加起来只要10刀），于是开映前在附近的Hyvee吃了顿饭。不知为什么少算了4刀左右，告诉了员工，员工也不在意。到场之后发现虽然场子很小，但是根本没有人来，只是之后来了两三人，四舍五入就是包场。内容，就是一般的好莱坞动作片，没有字幕所以有时候会听不懂。虽然之后也有枪林弹雨，但是子弹列车字面上指的是新干线。讲的是一群特工在新干线上从东京打到京都，最后死了几名特工，整列车都被整脱轨了。不仅仅是三方一两损的程度了。大家都亏大了。回来的路上才发现，自行车的前灯没了，只好重新买了一个。所以，到底是值不值呢。一说，是经验千金难买，但是问我想不想再经验一次，我大概也很难给出个肯定答案了。</p><p>之前打完金恋的时候也是这样。跑到湖边，看了夕阳。相较于游戏里的满目金色，现实里湖面只有一缕一缕的闪烁。然而就凭波光粼粼一词，恐是难以形容其刺眼。就算说是秋天的太阳照亮的湖面，哪怕是带上墨镜，也不愿意去直视吧，像我这种阳光下只会稍微变暗程度的眼镜，更是难抵其耀眼的光芒。触目难忘，讲的就是闭上眼睛，也能看到光斑。回想起来，如果少看手机的话应该更好了。我是为了丰富自己的内心，才去选择跟自己对话，跟大自然对话，跟自己心中的大自然对话的。写这篇博客，也是为了跟自己对话。正因为如此，才应该摒弃外界的骚扰，而直视自己的想法。不然，夕阳就只是夕阳而已了。之前去黄石国家公园，也感觉到自己想法的浅显，到了一个地方，只能拍拍照，感受一下大自然的鬼斧神工，就没有了。半点想法也挤不出来。明明自然在我面前展现自己的千姿百态，有美的一面，比如羚羊谷里暴洪冲刷出的各种图案，比如路上绵延的草原，有丑的一面，比如散发刺鼻气味的间歇泉。但是大自然不告诉你含义。含义需要自己汲取。黄石之旅有机会再详说。</p><p>说了这么多之后，第四部。是《Singin’ in the Rain》（雨中曲）。这是我分享了看完《子弹列车》之后，在频道里看到别的人最近看的作品，心血来潮在亚马逊上租了，当晚（说是当晚，其实是昨晚）麻将打了一半走人回家看的。大概也是1小时40分钟。嬉笑舞蹈之间讲述了电影业从无声到有声的迅速变迁。《La La Land》也是很久以前看的了，所以这种音乐剧特有的，二话不说跳起舞来的风格，让我首先想起的是印度的电影。可没想到上世纪的好莱坞就有了。我看到“call me a cab”“hey cab”这样的冷笑话也会禁不住笑起来，所以整篇看完非常愉快。挺喜欢男二的Cosmo，尤其是他的《Make ‘Em Laugh》。名作，也不一定就是深沉的，大概吧。</p><p>电影大概就是这些，游戏或者书的话，就下次再说吧。</p>]]></content>

        <content type="html"><![CDATA[<h2 id="写在前面">写在前面</h2><p>不用说也知道，本篇会有很多剧透。以前我大概会放一个大大的警示框在这里，列举一下包含哪些作品的剧透。但是我忘了怎么写的了。不过话说回来，提前告诉读者有什么剧透，难道不也是一种剧透吗？</p><p>那么，本篇大概包含金恋（金色ラブリッチェ）的剧透。</p><span id="more"></span><h2 id="金色时光">金色时光</h2><p>如果有人问，说到金恋，你脑海里浮现的是什么画面？</p><p>我的答案一定是那反复出现的，波光粼粼的湖面。</p><p>游戏里，关于湖的传说虽然一带而过了，但是死，确确实实是永恒的话题。过于永恒而不知该从何说起。就算说，可能也会是一些老生常谈，不过我还是想努力讲一些有意思的事情。那么就看我下面的发挥了。对一个人来说，死意味着物质的消失和思想的消逝，不过对他人来说，这个人的又意味着什么呢？我问这个问题，是因为想到，我好久没有联系小学的同学了。如果说，一个人的死意味着没法再见到他们，那么对我来说——我明白这个说法不好——现在的联系不上的状态和死了，没有什么区别。</p><p>我们的关系在渐渐死去，变成说得上一点点话的陌生人。</p><p>如果一个陌生人死了，我的感想，当然排除没有感想的情况，应该不是针对死者的，而是一些泛泛的、漠不关心的感想：人如何脆弱、人生如何缥缈，如此这般。</p><p>高中的时候，隔壁班就有一个同学事故身亡。但是我不认识他。有同学说，他挺开朗的，不可能是自杀；有同学说，可惜了。我没有说什么。那天晚上，教学楼下摆了一圈蜡烛，他的一些朋友在那里默哀，我也去了。看着摇曳的烛光，我想着我要好好活着。结束后，他的妈妈几乎说不出话来，但是还是安静地说了谢谢你们来。离开的时候看着他的父母，我隐隐担心他们的婚姻还能否继续下去。不过也就仅此而已了。</p><p>对更亲近的人，抱有的感情应该会有所不同。我的记性很差，很久以前的事情大都记不太清楚了。要提最近的事情大概就是外婆了。每次去姨妈家，外婆是最关心我的那个。新年的时候，甚至还会塞给我压岁钱。临走的时候，总是希望我很快再回来一趟。然而这几年，我因为种种原因未能回家。远程电话的时候，看着她期待的眼神，我口头上说会早点回来，但也不敢保证什么时候。就在几个月前，家父打来电话说，外婆过世了。听到消息的时候，我不知所措。然后我想起来了：我终究没能回去见她一面。</p><p>外婆肯定不会怪我，她从来也没有说过我一句坏话。家父也没有责怪我。责怪我的从来都是我自己。可是，生者如何快活如何悲伤，同逝者又有何关呢？活的人永远没法替死人着想。所以我想，这喜怒哀乐大抵都是要归结到自己身上来的。</p><p>话说回来，只有归结到自身上来，才能成为实实在在的感觉。他人的小脚趾撞到桌角，与我又有何干？肯定是大笑一场。在纪念一些人的时候，有时会说没有X就没有Y，这也是把逝者的所作所为跟我们的现在联系起来。不然，光荣事迹再光荣，换来的大概也就是个无声的“哦”吧。</p><p>这里就用葬礼之后的问答收尾吧。可以算是在身边人过世后心理活动的一个例子吧。</p><p>“我有在闪闪发光吗，她没有对我失望吧？”</p><p>“我真的成为世界上最帅的男友了吗？”</p><h2 id="其他一些最近玩过看过的作品">其他一些最近玩过看过的作品</h2><p>Judgment，这个就死很多人了。大家都是硬派，没什么话说。</p><p>52赫兹的鲸（52ヘルツのクジラたち）。标题的来源是源自一头特别的鲸。通常鲸声音的频率在10-40Hz，而这头鲸的声音却超出了这一范围。因为据称别的鲸听不到这个频段的声音，人们称它为“最孤独的鲸”。这头鲸数年来没有被找到，只有它的声音飘荡在海洋里。全本书里我觉得美晴是里面最讨喜的人物了，最后她回去的时候我眼泪掉下来。我在想，天鹅之歌是不是也能用来形容这些没有被听到的SOS呢？查了下词典，再仔细想想，还是没那么像。</p><p>三体。看完之后有点激动，第三卷那个时间跨度大的不得了，有些追不上。</p><p>Ratchet &amp; Clank, the game和rift apart。这个两纯粹是老少皆宜的有趣游戏。</p><p>LUNARiA。不错的作品，我还在等松山写流星群的下一卷。</p><p>白金数据。开头居然有像是harmony的梗（人人身上装着IC芯片，由政府监督一举一动），有点快乐。</p><p>大概就这么多。如果要问我是什么刻骨铭心的内容的话，我说不上来。好酒也是要反复品才能出味的，像我这样，囫囵吞枣，不加思考地吸收，可能最后就忘得一干二净了。</p>]]></content>

      <title>The Rise and Demise of Twitter 2</title>
      <link href="/posts/twitter2/"/>
      <url>/posts/twitter2/</url>
      
        <content type="html"><![CDATA[<p>This is written to memorize the discord channel Twitter 2.</p><h2 id="Some-Random-Ranting">Some Random Ranting</h2><p>Not for everyone, but people recently are getting increasingly prone to anger, and cancel culture and exclusionism are prevailing. The world is going into pieces.</p><p>Yet the Internet itself is just a system which was invented decades ago for connecting computers. It’s always the human that is the problem. Originally to obtain social interaction, a person must blend into a group that they share little similarity with. This is getting less and less true with the introduction of social media, where people can find those who share great interests with them, share the same political stance with them, and share the same worldview with them. The same applies to receiving information, people now can easily find news that they love to see, views that they are supporting, or videos that they enjoy watching. “Why bother to watch things that I dislike? Why bother to talk to people that I dislike?” And they push themselves into a comfort zone, surrounded by only things they like. I’m doing it, for sure, and many people are doing it.</p><p>Also, tech companies behind social media are pushing this further in the name of “personalization”, because they know that this is the best way to make people stick with them, hence the best way to make money. As a result of this push from both sides, a person is more likely to only get to know a group of people like them, watch news that only say things they want to hear. Everyone lives in their own tiny world now.</p><p>Ridiculous it is, that the Internet was designed to connect people, but now it is segregating people.</p><p>Let me now imagine an extreme scenario, where Ant runs into Bat on the Internet. The problem is that Ant likes a film called Eekum, but Bat doesn’t, and thinks another film called Bokum is better. Tech companies are good at separating people due to their tastes, but they are not perfect, so understandable. It’s not like Ant doesn’t try to get along, Ant tries, to tell Bat how good Eekum is, and Bat does the same: tell Ant why Bokum is better. After some futile attempts, Ant can’t make Bat agree what Ant thinks. Because Ant hasn’t have a friend that loves Bokum, Ant thinks “maybe I just cannot get along with this type of people”, and by “this type of people” Ant means people who like Bokum. So, Ant just gives up. Later, Ant runs into Cat who also like Bokum as well, instead of talking with Cat, Ant thinks — “I can’t get along with someone like Bat”, so Ant walks away and never talked.</p><p>And sometimes I feel like I’m Ant, constantly under the influence of bias. Bias is the assumption of something we don’t know. We may assume the best or the worst of someone before even getting to know them. I understand that bias naturally happens, but oftentimes still falls into its hands, and make judgment based on bias. Why bother to learn more about someone I may hate, if I have plenty of people that I know I’m more probably to love? In such a way, people divide themselves into smaller and smaller groups. The segregation, in return, may fuel the bias, and mob mentality, to make people offensive against disagreements, in desperate attempt to defend their belief.</p><h2 id="The-Inception-of-Internet-2">The Inception of Internet 2</h2><p>Above is just my personal view, and Nyarla also feels tired of wars in the Internet. He comes up with the idea of Internet 2 in the book with the same title in 2019. In <em>Internet 2</em>, Nyarla imagines the outrage in Internet being overwhelmed by kindness, sympathy, and harmony.</p><blockquote><p>優しさがインターネットを支配する時代となる。It will become the era when kindness dominates the Internet.</p><footer><strong>Nyarla</strong><cite>Internet 2</cite></footer></blockquote><p>I use the word “harmony” because the whole idea of Internet 2 reminds me of the book <em>Harmony</em> by Project Itoh. <em>Harmony</em> portraits a dystopian world where everyone’s body is deemed the possession of humanity, and people’s minds are monitored to prevent any damage done to anyone including themselves. There is no dictator, but the collective mind is dictating everything.</p><p>Internet 2 might be something similar: everyone is forced by everyone to be kind, although “that kindness may not correspond to kindness in real life”. But in return, in Internet 2 there is no dissonance. People are happy.</p><p>But when it comes to Twitter2, things are a bit more complicated.</p><h2 id="Twilight-of-Twitter-2">Twilight of Twitter 2</h2><p>In Jan. 2021 Nyarla <a href="https://note.com/nyalra2/n/nbb2d6fbf1d34">set up the Twitter2 discord server</a>, dubbed “a truly happy SNS where everybody does not talk about politics or society, but watch anime and play games all day”.</p><p>In the short manga that introduces Twitter2, people are depicted as brains in jars, and Nyarla, depicted as a little girl, is taking care of them.</p><p>In the post Nyarla wrote that Twitter2 started from a joke. And he created it partly because someone asked him to do it and he’s interested in running Discord server, partly because “it’s interesting to make such a dystopian-like [Discord] server and have a community of otakus”.</p><p>Therefore, although Twitter2 shared some dystopian (or utopian, YMMV) nature with Internet 2, it was nowhere as extensive as the Internet 2, and was just a discord server of otakus. From a larger perspective, Twitter2 is the reflection of the Internet instead of Internet2, where people are in a smaller circle.</p><p>Nyarla’s note told a little about what’s in Twitter2, so I think I may also write something different.</p><h3 id="Channels">Channels</h3><p>Aside from hobby channels, like anime, game, manga, movie, books, etc., there are also channels that people share pics of animals, landscape, food, and talks about life, religion or private things.</p><p>Religion was one of the recently established channels. It probably spun from a discussion about whether God exists. I didn’t look into the channel very much, but it is interesting to see people talk about belief in a more open and objective way.</p><p>Liminal space is another one of the new channels. Pictures of empty space were posted there. Nyalra sometimes would repost liminal photos from twitter. He still does this sometimes. I also took a photo or two to post there but couldn’t find a good shot here where I live. Some photos there are interesting. Empty hallway, or even an empty room (not so liminal by definition, which confuses me a little), but I enjoy all the pictures there.</p><p>Some channels I visited most:</p><p>General: of course, most talk happens there.</p><p>Monologue (ひとり言): sometimes I’d like to write my thoughts there. There’s another channel called the wall (かべ) where harsher monologues were written. I couldn’t distinguish the difference until I learned about the phrase hitting wall (壁打ち), one of its meanings is to let things out alone.</p><p>Poison radio (毒電波): People were writing random things there. Most of them sounded crazy, which made me a little nervous and anxious. And that made me feel interested. The one I can remember most clearly is “the earth is targeted” (地球は、狙われている from Ultraman), because there was a person (nicknamed erson, with an icon P, if I got it right) posting it almost everyday. There’s a saying that if someone keeps repeating something it will be hard for you to get it out of your head. Here it proves itself again. “Poison radio” came from Leaf’s first visual novel Shizuku (1996). I took the English translation from the song INTERNET OVERDOSE, whose lyrics was by Nyalra.</p><p>Books (本): As I read books (lightnovels) much more than watching anime or comics. Sometimes a message popped up with a photo of newly bought books, or about a book recently read. There, I came to know Kazuki Sakuraba’s other works, and before then I only read GOSICK by the author. One of them being A Lollypop or a Bullet. It’s a story about a girl that grows up, with a girl that doesn’t have the chance to grow up. I also learned about Nobel Laureate Kazuo Ishiguro’s new book, Clara and the Sun, although I hadn’t read it until the server shut down.</p><h2 id="The-Sudden-Sunset">The Sudden Sunset</h2><p>Around the end of 2021, griefers appeared in the discord. Though I started writing it during Nov 2021, it is now May 2022, and I couldn’t remember things clearly, so I’ll try my best.</p><p>First there were spamming discord invites. Come join us to spam other servers, it said.</p><p>And another time, all channels were spammed with defecating GIFs. Because discord plays the GIF by default people are forced to see it. The server is down for a while, and it came back with bot administration to counter spams.</p><p>And finally, the server just disappeared. I didn’t know what happened until a friend told me attackers got it down.</p><p>From <a href="https://note.com/nyalra2/n/nbfb2aa75577b">Nyarla’s post</a>, the attackers used the below method to get the server banned:</p><ol><li>Use anonymous accounts to spam access tokens in the server</li><li>Report it to Discord</li><li>Discord bans the server due to TOS violation</li></ol><p>From a third person’s perspective, I’d say it is an incredibly elegant method, which achieves the most destruction with the least effort.<sup class="footnote-ref"><a href="#fn1" id="fnref1">[1]</a></sup> And Discord’s lack of scrutiny before banning users and servers make this attack possible.</p><p>As a member, I wanted to say something, but surprisingly found myself at a loss for words. And at this time, 3 months after Nyarla set up a new server, and half a year after Twitter2’s disappearance, there’s nothing I can say about it any more. Some time it went just like that: people find themselves attention via the social network, but at the end, they don’t really need it.</p><p>And with that it concludes Twitter2’s short life.</p><h2 id="Footnotes">Footnotes</h2><hr class="footnotes-sep"><section class="footnotes"><ol class="footnotes-list"><li id="fn1" class="footnote-item"><p>I thought this kind of method is more often done in China, where ill-minded people utilize other’s careless words to get them banned, especially if they something remotely bad about the government. <a href="#fnref1" class="footnote-backref">↩︎</a></p></li></ol></section>]]></content>

        <content type="html"><![CDATA[<p>大家好，这里是很懂C++的BlancJpg。</p><p>Memory order是什么？哎呀怎么这个都不懂。Memory order不是很简单嘛！Memory是记忆，order是顺序。理所当然，memory order是记忆的顺序！当然，我记性不是很好，经常记不清顺序——卡特列夫库——是什么的库？</p><p>拿昨天的早饭做例子吧，我吃的是面包夹肉饼——好吃吗？嗯……还行吧——我记得很清楚，我先吃了面包再吃的肉饼的。</p><p>……什么？原子化？对对对，我的牙齿是先碰到面包，再碰到肉饼的分子的。所以从分子层面上来说我是先吃的面包。你呀，明明是分子说什么原子化。难道是要把分子劈开吗？想裂变吗？</p><p>就说是先吃面包了！麦当劳的肉饼比较x……好了好了换个例子！拿前天做例子吧，我是先吃的早餐然后吃的午餐。——我说吃早餐了就是吃了！别多管闲事！所以从正常人的眼里来看，我肯定是先吃的早餐然后吃的午餐，除非有人在超光速运动。啊不对，如果是超光速运动的人，那就不是吃了，大概会看到我先吐出午餐，再吐出早餐。像小红帽故事里的大灰狼一样。所以是小红帽在超光速运动。谁也没看见大灰狼吃奶奶的场景对吧？没看见就是一切皆有可能。</p><p>大灰狼记不记得自己点了什么菜呢？毕竟是order……哈哈！</p><p>讲到哪里了，讲到晚饭了。前天的晚饭吃得比较快活。吃的羊肉串加牛肉面。饿了一天的肚子也填饱了。——所以讲吃早餐了！话真多呢这家伙！走了！</p>]]></content>

      <url>/posts/ja-diary-20210320/</url>
      
        <content type="html"><![CDATA[<p>…っと勢いで言ったものの、なにか書くこともないので実際無謀だった。</p><p>これは、日本語の練習として発案された。私にとって日本語は母語でもないし、英語みたいに学校で勉強したこともない、ほぼ自学です。なので練習する必要がある。じゃないかな。だからこうして言葉を綴るのも一つの勉強ではないか。とりあえず、何も考えずに書くだけ。</p><p>真っ先に考えられるのは、どうすればこの文章を長く書ける方法だ。最近さくらもゆ遊んでるので、そこに言い換えることが多いのが気になる。そして、これも一つ文章を長くする形ではないか。しかし、それを読む人はどう思うのだろうか。私自身の感想は、言い換えれば言い換えるほど、会話の流れが連続ではなくなる。加えて、話し手が頻繁に言い換えることは、自信がないではないでしょうか。私英語でしゃべるときもよくあることだから。このワードで正しく伝えているのかって反射的に悩んで、もう一つの言葉を思い浮かべたならそれを即採用する傾向がある。しかし、言い換えてもなんの用もない場合は多数だな、と顧みてはそう思う。</p><p>よく考えれば、これも、小さなパニックではないか。なにか言い間違ってないかってパニックして、そして優先事項を見失ったではないか。だから、これはパニックは最悪につながるの、もう一つの証拠です。</p><p>でも、よくないって思っても、試してみたい心は私にはある。だから、これから、私もすこし言い換えて、言葉を遊びましょうか。</p><p>日記においては、近況報告もひとつの慣用のトピックだ。日常生活になにかを感じて、霊感、あるいは、ひらめくことも多いではないか。とはいえ、あんまりプライベートなことは報告しないつもりでいる。秘め事はやはり、自分に全く関心のない人や、自分に気遣いできる人に限って言う。</p><p>どこか出かけたら報告の材料にもなるが、残念ながら今のアメリカではそれは難しい。今はひたすら家（アパート）にいって、コロナ暴露の数字を眺めるだけ。最近が０になってる、数週前７や８もあったので、感染者みんな病院に移住したか、治ったかなんでしょう。ちなみに、二週前食料買いに出たら、そと盛大なパーティーも上げていたんだ、百人はあると思う。学生みんなマスクしてない、食い物飲み物していて、ごく普通のパーティー。彼らにとって、唯一異常なものは、このご時世だろう。終わっただと思うから、終わっていない、そういうこと。</p><p>もう一つは、韓国語を勉強してることかな。日本語で韓国語のこと言ってるのは確かにおかしいだが、言語はいろんなどこ似ている。例えば、数字の言い方も二つある、一つは中国語の発音から来た(il, i, sam, sa, o)、もう一つは自ら発明した言い方で、主に数える時に使う(hana, dul, set, net, daseot)。もう一つは曜日を使ってること、例えば、日曜日は il-yoil（ilは日で、yoは曜）。文法も少し似ているような気がしますが、あまり文法について勉強してないので割愛。</p><p>一か月前くらいで、ピアノを買ってました、ヤマハのP71です。グリーンハンド、初心者なので、それに適するではないかな。主に、音ゲーやる時間があるなら、一つ楽器でも勉強した方がいいではないかと思った。以前やってないのがちょっと悔やまれるが、それはそれでもっと自由の幼年を過ごせたので、どっちがいいか簡単に言えない。興味というのは、いつでも、当時のやりたいことを重んじることだと思う。興味が変わればそれに従い、現在を楽しめること。 Carpe diem といって、同じ名前のゲームが steam にあります。遊んではいないので、おすすめできないが。</p><p>思いついたことはこれくらい、すみません、言い換えることあんまり出来ていなくて、これから本番で、最後のチャンスです。しかし、雑談なので、どうやって括ろうかを悩む。最近、村上の UT（一応ユニクロのシャーツと説明しよう）出てるんですけど、すぐに完売してる。カフカのシャーツとか。20日現在 1q84 以外ほとんどなくなって、 Ebay で二倍の価額で転がっている。ノルウェーの森のカバー色柄のシャーツも全部売れたのに（英語版は赤と白と黒で、日本語のと違う）、なぜ 1q84 は売れていない。みんなもっと 1q84 を買おう、と世界の中心で叫びたいが、自分一服も買っていない。配送料が高いのでやめた。</p><p>これをブログにアプロードしようとした時、WSL がネットに繋がらない、めんどい。</p>]]></content>

      <title>二之路</title>
      <link href="/posts/otaku-journey/"/>
      <url>/posts/otaku-journey/</url>
      
        <content type="html"><![CDATA[<p>我很早以前就像写一点东西记录一下自己二次元的心路历程了。我的记性算是差人一等的，很多年前的事情也记得七零八落的了。也正是因为如此，我希望能在脑子变得一干二净之前能尽可能多的记录下来，所谓“salvage”大概是如此吧。因为记忆问题，如果有差错也大概死无对证了。</p><p>至于“二之路”的名字，上文也已说明，取（我的）二次元的心路历程之意。我有想过命名为二史，但转念一想，我一个无名小卒，有何自信给自己立史呢。如果我是某一位有名人物，倒是确实可以以列传称呼：二史某某列传。然后为人耻笑罢了。</p><p>不过话说回来，如果这篇半回忆、半打岔的文章，能让读者有那么一点怀念，那也算是值得了。</p><p>为了克服羞耻心理，也增加可搜索性，我会尽可能地至少用全名称呼一次作品或者其他事物而不是全部用简称或者诨名。但是详细介绍这些东西的责任还是交给百科了。物语系列的羽川翼说，我只知道我知道的东西。这次就让我来借用一下这个重言式。（重言式应该是 tautology 的翻译， tautology 除了有真理之意，也有废话的内蕴。这就所谓真理都是废话。道可道，非常道。）</p><p>想起非常道，我就想起那张插画里有饼干的游戏王卡了，名字应该叫<a href="https://www.db.yugioh-card.com/yugiohdb/card_search.action?ope=2&amp;cid=5350">非常食</a>，可能台湾不叫紧急食物，于是就这么印上去了。</p><h2 id="黎明期">黎明期</h2><p>故事大概要从我小学时候说起。我爸给我买了一个黑色的 PSP3000。虽然玩零式的时候我确实有点怀疑这是不是2000了，但是看了一下对比图的的确确是 3000。那时候国内也不知道有没有正版小碟子买，就靠破解来装一些盗版：拿来的时候是显示一堆机器人——那时候我不知道变形金刚和高达有什么区别——的图片，然后最后一张是那个攻壳机动队的的笑脸男。后来换了一套，就变成鸡蛋图了。</p><p>小学到初中一二年级的时候我手上最好玩的东西大概就是这个 PSP 了吧。那时候我玩的最初的几个游戏里，有点印象的大概是歌姬计划 extend 。是 ex 而不是 歌姬计划 2nd 的原因，为我是按时间从后往前看的。就算我看不懂 MISS x TAKE 或者 CHEAP，听不懂初音或者镜音或者谁谁谁讲的什么日语，看着他们垂头丧气，也能知道那不是你打的很好的意思。比如第一首猫耳开关，我就是打了很多遍才终于过关的。不过我并没打完 —— 普通难度全过关，看到制作组名单还是非常非常后来，几年以后的事情了。</p><p>玩了节奏游戏，视奸在房间里的歌姬之后，我似乎还不够满足。还想去看看别的图，比如说色图。那时候百度搜图有时还会有漏网之鱼，所以碰巧撞上一两张越线的是完全有可能的。不知道该说这样的百度搜索是好还是不好，总之我碰到了不是初音的图，是一个大胸二次元妹子洗澡的图，我本能的去搜这位动漫人物是谁，结果告诉我，这是《我的朋友很少》的柏崎星奈。这应该就是我看的第一个我百分百有信心，可以算作二次元的动画了。换做现在我是不会去看友少动画的，不如说动画基本都不怎么看了。</p><p>那时候我也经常逛贴吧，初音后面跟两个不认识的字的吧、和友少吧我是常客。不发言的那种。所以周刊什么的也时不时会看看。这个吧把初音未来吧吞并，匹诺曹P 被称为汪峰P，等等，都是之后才听说的事情了。</p><p>另外一个让我印象深刻的游戏是秋之回忆 6（或者不意译，直接叫 Memories Off 6，简称 MO6）。那时我还非常纯情，打完远藤莉莉丝线之后，就怎么也不想打箱崎智纱线了。Bad end 也不敢打。唯一另外通关的一条线是学姐线，不过那也是很久之后的事了。MO6 除了是我打的第一个 galgame 以外，一个让我印象深刻的地方，就是番外小故事没有翻译，成了我学日语的契机。不过多年以后回来看，才发现全都是乱码，我还是看不懂。</p><hr><p>不知放这里是否合适，小学的我还受一位好朋友影响，玩起了口袋妖怪（现在有正式译名了），绿宝石。那位朋友选的蜥蜴，我选的火鸡。他还给了我很多指导，不然我肯定就因为卡关而不玩了——我属于不看剧情的流派。Grand Theft Auto Vice City 我从来都没做过主线任务。玩无主之地2的时候也是，我英语也不好；接到什么任务也不会切换，就都给做了；只会往白点跑然后哒哒哒；只记得小手指那么大的剧情。而不看剧情经常就让我不知道该往哪里跑，现在的游戏基本都有任务列表了，我也会读点英文了，把任务拎出来给我看这种设计可谓是我这种大脑退化玩家的福音。</p><p>言归正传，不知是不是字库限制，感觉有些名字非常奇怪。而且存档好像不利索，通关了就掉档了。总之那个 ROM 不行。那时候动画也有再看，不过大约看到成都地区就没再看了。虽然严格来说的确是二次元，但毕竟是儿童向的动画，所以跟本文的意趣并不完全相投。这就好比抓住一个日本人问，看海螺小姐和鬼太郎算是宅吗，人家估计也很为难。</p><hr><p>那时候也有在用村规打盗版的游戏王，动画也有看那么一点，总之黑魔导女孩（<a href="https://www.db.yugioh-card.com/yugiohdb/card_search.action?ope=2&amp;cid=4766&amp;request_locale=en">这里</a>，第一张）非常色。休伯特（<a href="https://www.db.yugioh-card.com/yugiohdb/card_search.action?ope=2&amp;cid=7409">这里</a>）也色，直到我认出来那是男人的身体之前。</p><h2 id="全盛期">全盛期</h2><p>以友少为起点，我感觉自己看了很多动画，但实际上一点也想不起来。我登陆了优酷土豆账号，虽然草刺猬的头像暗示了我从小学起就有这个账号了，但是历史记录却是像海浪冲过的沙滩一样干净，一点痕迹也不剩了。</p><p>好事是我有时及其闲得无聊，会在我的 iPod touch 上记录一下今天看了些什么，有的时候会记录一下看了些什么。那时候我还会记到我的一个步步高学习机上。这个学习机除了日常拿来查词，在物理和化学实验软件里试试各种东西以外，大概就用来看 V 家（包含初音的 Vocaloid 家族的简称）的 MV 和看看小说了。这个学习机上也有那个历史的只鳞片甲了。不过那个学习机尘封已久，也不在我手上，所以是无门了。如果挑我还记得的来说：</p><ul><li>保存的 PV 有<ul><li>DECO*27 的 ゆめゆめ —— 我当时觉得这个故事很好很喜欢，以及有可爱的动画。</li><li>n-buna 的 ウミユリ海底譚 —— 很喜欢旋律，以及有奇妙的插画。</li><li>一两首阳炎，但不是很确定，阳炎 Project 之后会讲到。</li></ul></li><li>看过的小说有<ul><li>《我女友与青梅竹马的惨烈修罗场》（简称俺修罗），这个是我印象里最先看的轻小说。原因是被标题吸引，看了动画第一集之后觉得很有意思，然后不想等一周只有一集的动画。所以应该是 2013 年 1 月。</li><li>精灵使的剑舞。</li><li>西尾维新的物语系列。</li></ul></li><li>还有一些看番记录，因为没有日语输入，所以尽可能地在用罗马音，有印象的有：<ul><li>赤眼的夏娜（第三季因为没看懂就没看了）、Fate Stay/Night 、武装神姬、零之使魔、命运石之门、电波女与青春男</li></ul></li></ul><p>我在 U 盘里也保存了从动漫之家（那时候好像还是 178 动漫）下的物语，凉宫春日，和奈亚子的轻小说的 txt ，供上机的时候看。</p><p>回到记录上来，iPod touch 的记录倒是有云上贵州给我留着，摘录几个以供观赏：</p><p>2012/1/13</p><p>“看了”</p><p>没有别的内容。大概是记录了我那一天看了什么，但是出于什么原因没有记下来。</p><p>2012/1/23</p><p>“おはよ,sinnen。”</p><p>至少这时候开始学平假名了。虽然说 MO6 是潜在动力，最直接的学日语的原因还是因为想学唱歌吧。最先会唱的是千本樱，那时候是对着罗马音唱。那时候我假名输入用的不利索——这也是我 Miku Flick 不会打的原因之一，另外一个原因就是菜——所以估计是用的罗马音键盘。</p><p>2012/1/30</p><p>“何も無い。(^_^)”</p><p>确实除了这句话什么都没有。</p><p>2012/1/30</p><p>“1.２３のsinnen-&gt;sinnnen 新年”</p><p>“1.23 おはよ-&gt;お早う”</p><p>一些更正。N 到底要不要多写一个我到现在还不是百分之一百肯定。</p><p>2012/11/25</p><p>“FSN 7 14:55SAO 21武装神姫 8Robotics;Notes 7ハヤテのごとく 3 8”</p><p>FSN 指 Fate Stay/Night, 14:55 可能是看到 14:55 的意思。SAO 是刀剑神域的英文首字母。最后一个是指旋风管家的第三季的第八集，这是那一年的冬季番。如果仔细看的话，这里的武装神姬，其实最后一个字是姫。鉴于那时候我不知道这个字念 cheng 上声，这应该也是用日语输入法打的。</p><p>2013/1/1</p><p>”Bakemonogatari  1-11</p><p>2013-1-1</p><p>Happy new year!“</p><p>明显我在这一天看了化物语的 1 到 11 集。</p><p>之后最早的记录就到 16 年，我上大学之后了。冒头的是这个 copypasta：</p><p>2016/11/16“总有人问我，笑话我，都十八岁的成年人了，大学生或者是高中生了，还玩这些废萌的海王星什么的有意思吗？</p><p>海王星大概是我们这一代青少年的回忆之一，“就像打碎Uzume的水晶”。海王星自然是一系列以盈利为目的的游戏，但是也是日本的neta教育游戏之一。诚然，从一开始，很多人因为海王星系列的“地雷”而放弃了后面的海王星。但是，CH拿到了更多的钱，也确实把一部又一部海王星做的越来越好。超次元尝到了初代的甜头，mk2开始变得深奥而寓意深刻，U又把动作带入了故事里。到了神次元，Victory自不必说，PP又是一部暖心之作。</p><p>到了去年的新次元，海王星的neta已经让我这个成年人开始深刻反思：已经成年的我是否深刻的理解了梦与希望，羁绊和抉择？很多人觉得海王星是一部萌豚游戏，但是萌豚时候的我们真的能完全吃透其中的内涵吗？就像父母不理解Nep一样，我们也可能没有理解Uzume。并非智商并非情商，而是我的“心商”没到吧。空有应试教育拔高的智商和中国式迂回套路情商的我们，或许还需要一颗坚定的心来带我们走对路。而相比于我们作为并非硬核玩家去看热评的各大3A，我宁愿选择玩懂我自以为萌豚时候就懂了的海王星。”</p><p>海王星替换的是什么我记得不太得了，隐约记得这是发在日语协会群里的玩意儿，所以大概是奥特曼吧，那个群里有个喜欢奥特曼的人。</p><p>除此之外，我也用这个 iPod touch 存了一些轻小说，如上面提及的放在 U 盘里的那些。</p><hr><p>我有印象的追番是从 12 年的冬季，《中二病也想谈恋爱！》开始的。前半段是在优酷看的，后半段在 Bilibili ，也就是 B 站上看的。那时候看别人都在结尾撒花，而我没有 B 站号，于是就把完结撒花发到 QQ 空间里去了。如果有小学同学知道我是死宅，那这大概就是原因所在。同时期的武装神姬我也在追。《刀剑神域》虽然也在追，但是也是在后半段（日语和英语会用 cour 来指跨季度的一季动画，和 season 区分开来，我是从第二个 cour）开始追的。</p><p>13 年春季追的番也无史可考。B 站只保存了 3 个月的历史记录。上面说的《俺修罗》也是看了小说之后就没看动画了，《魔王勇者》似乎也是这样。唯一有印象的是《我的妹妹是「大阪大妈」》。从那时候我就有了优先原作的倾向：会优先去看原作的轻小说或者漫画，而不是看改编动画。</p><p>那段时间我也第一次接触了 R18 的 galgame 。途径大概是那时经常上的毛站（ <a href="http://acgzone.us">acgzone.us</a> ，现已关闭）上看到的，被司田的作画吸引而下载的《五彩斑斓的世界》（由于其日文名，也被称色鸟鸟）。因为打完《世界》之后开始打《五彩斑斓的光芒》（也称光鸟鸟，不过原名顺序应该是鸟鸟光），而《光芒》我有的最早的存档也是在 13 年，因此推断是在 12 - 13 年通关色鸟鸟的。当时很喜欢黑长直。</p><hr><p>同样是 13 年，Vocaloid 我还很经常听。Jin 投稿的《Loss Time Memory》仅用一个月就在 niconico 突破百万播放，而以此为契机，我也接触到了 Jin 的一系列共享世界观的歌曲，这个系列被称为《阳炎 Project》。我依稀记得当时想学唱这首，和 n-buna 的《夜明けと蛍》。</p><p>我有印象的此类 vocaloid 歌曲的媒体化中，只有阳炎是走的最远的——书籍化，漫画化，甚至动画化。虽然我不太记得动画的内容了，只记得每集对应一首歌。像平成 Project 停留在歌曲，终焉的书签 Project 也因为 suzumu 中道崩殂而不了了之。2015 年及以后，我就没怎么关心 V 家了，至少贴吧是再也不逛了，所以这类消息就不得而知了。</p><h2 id="平缓期">平缓期</h2><p>上了高中，我感觉自己过得就是一个正常人的生活了。除了每周末回家的时候能得闲，住学校的时候跟二次元基本是无缘的。而在高中的这段时间我也一点记忆都没有。除了读了英文版的《1984》和《挪威的森林》以外，就不记得有什么课外活动了。</p><p>学校里，就像许多其他学校一样，都有一个动漫社。不过我没有加入。</p><p>印象里我还是看了很多轻小说的，但由于没有记录，也不确定是否是这段时间看的。比如说，当时学院战斗类型的轻小说井喷，我也看了不少：新约某魔法的禁书目录、绝对双刃、学园都市的六芒星、盟约的利维坦、最弱无败的神装机龙巴哈姆特、绯弹的亚里亚、三坪间的侵略者、如果折断她的旗，等等。还有许多名声不大的。这些书基本都是只记得看过，不记得内容，过目就忘的那种。因为忘了剧情，也就没有追下去了。</p><p>为了找书，我也经常去轻国论坛转悠，不过没混出个名堂来，大多数锁权限的书依旧看不了。</p><p>动画也时不时有看，但是不记得有看完的。基本是去看原作了。再者，人气大的作品基本都是动画化的，所以我这里照着萌娘百科的列表，来列一下13-14年除了上文提及过的，我看了原作的动画。</p><p>13年：学生会的一己之见、GJ部（少有的我追完了的动画）、问题儿童来自异世界？、打工吧!魔王大人、我的青春恋爱物语果然有问题、约会大作战、我的妹妹哪有这麼可爱、人鱼又上钩（这个没看多少，另外一个跟人鱼结婚的漫画倒是看完了）、变态王子与不笑猫、要听爸爸的话、只有神知道的世界、High School DxD、侵略！乌贼娘、出包王女（和 Darkness）、机巧少女不会受伤、我的脑内恋碍选项、萌萌侵略者 OUTBREAK COMPANY、Strike The Blood。</p><p>14年：伪恋、属性同好会（可能是后来才看的）、漫画家与助手、漆黑的子弹（还在等第八卷）、No Game No Life、剑灵（玩了一会儿就退坑了，网游不适合我）、希德尼娅的骑士、棺姬嘉依卡、星刻的龙骑士、目隐都市的演绎者（也就是之前说的阳炎 Project 动画）、斩·赤红之瞳！、月刊少女野崎君、日常系的异能战斗、甘城光辉游乐园、记录的地平线。</p><p>不过很多我也没有看到完结（比如棺姬只看了前两卷）。再者因为我也不经常去逛 B 站了，而是更多地逛轻小说站，所以看书和漫画的时间也不一定就是紧跟着动画播出。</p><h2 id="复发期">复发期</h2><p>上了大学之后，整个人似乎放纵了许多，漫画和轻小说又看了起来，但动画是基本不看了，就算是看，也少有能看完一季的。印象里有看完的有 2017 年的兽娘动物园，2018 年的 Pop Team Epic。没看完的有野良神，紫罗兰永恒花园，等等。</p><p>游戏也多打了很多。虽然在 2013 注册的 Steam 账号，但买第一个游戏还是直到上大学，有了银联卡才有的事，那是 2016 年。顺便一提，我买的第一个 Steam 游戏，If My Heart Had Wings，只打了一个开头，到现在都没打完。</p><p>如果用一个词形容高中到现在我的二次元历程的话，那就是始乱终弃。比起打完的游戏，永远是没打完的游戏多。看完的轻小说远不及没看完的（连载太长可能也是一个原因，比如农林）。</p><p>换言之，上了大学之后，我看的轻小说更偏向于短篇，少有名气的那些了；另外一方面，玩的游戏明显增加了，至于玩了哪些游戏，还有日渐疏远的动漫到底怎么了，就请听下回分解吧。如果有人希望有下回的话。</p>]]></content>

      <title>Sepia Memories -- Let&#39;s Talk about Sepia Tears, and some Free Games</title>
      <link href="/posts/sepia-memories/"/>
      <url>/posts/sepia-memories/</url>
      
        <content type="html"><![CDATA[<h2 id="Back-to-2016">Back to 2016</h2><p>I was an undergraduate then, and I had an Honor 7. One of the memories I had with that phone is searching everyday for a Marshmallow update. Don’t get me wrong, I still think it good to have an Android phone for the freedom it provides, although I make do with Apple for now.</p><p>And at that time I was hunting for some free games in the play store. Android phones usually don’t have access to Google services in Mainland China, so most cases I would check out some third-party app markets for applications or games. Except when I expected something different.</p><span id="more"></span><p>For example, some games that do not have a Chinese language support. More so if it is as minor as something like visual novels. And that was what I decided to go treasure hunting for. Of course I did play those Temple Runs and Flappy Birds, but I may not digress here.</p><p>A note is that there are always better games out there, perhaps with a high price tag. So while you feel free to enjoy these games(partly cause they are free), it is also perfectly fine to pass and play those paid and better games. But sometimes it is real fun to find out whether a game is good or bad for you.</p><h2 id="Lily’s-Day-Off">Lily’s Day Off</h2><p>It is one of the first games I ran into, according to my Play Store records. The game is developed by Kyuppin, and freely available on Appstore or Play Store, with some ads(you can pay $4.99 to get rid of them for good, but the game does not force you to pay to unlock anything), and on Steam for a plain $4.99.</p><p>Something different with Lily is that the game begins with no information about either the protagonist, or the heroine Lilypad Lily. Who they are and what they do depend completely on player’s choice.</p><p>There’s a phrase in Japanese called “atodashi settei”(lit. afterhand settings), which describes the phenomenon where the author introduces new settings mid story to push the plot, instead of making them clear at the beginning. For instance, the protagonist is revealed to have some hidden ability in an emergency. Or some new characters to save their ass(Deux ex machina might be a better word for this). Since it destroys predictability of the story, guys reading detective fiction hate it so much that one of them called Ronald Knox stood out to recommend against it and some other things that ruins the fun.</p><p>So it is interesting to see someone make it to an extreme. The protagonist might be a serial killer, a stalker, or Lily’s best friend in different routes, and Lily can be a yandere, a sadistic torturer or even someone who wants to nuke the human. The game’s short, but full of absurdity of this kind.</p><p>When I was writing this article, I found out it has a sequel, similarly named Lily’s Night Off, featuring the same inanity but with much better quality, and a somewhat anticlimactic ending.</p><p>There are a lot of beatiful graphics which we can’t see in the previous work, and I found my self quite into the soundtrack. Some cons are that it is so short that it only takes half a hour to finish, and the writing a bit childish.</p><h2 id="Sepia-Tears">Sepia Tears</h2><p>I named this post after the game’s name. Made by Team NEET(now Scarlet String Studio), it is a short VN(a few hours) with no ads. Yes, one thing I love about it is that it is completely free.</p><p>The protagonist, Mark, runs into a mysterious girl in an afternoon on top of the school building. The girl names herself Myra, and wants to remind him of something that happened 3 years ago. As the story progresses, he finds out about the worries of people around him — his classmate and his little sister, and helps them get over the obstacles. And finally, he faces his own feelings, and the mystery of Myra reveals.</p><p>The game takes much longer than Lily’s Day Off, I’d say a couple of hours. The writing is giving me a strange feel, the characters feel a bit cold and distant, just like a usual winter morning. And Myra is the candlelight giving out some warmth in this sensational journey of loss and found.</p><p>Except a bit cynicism, and some big talk that may put one off it a little, here are some dialogs that may give out that kind of atmosphere a little.</p><blockquote><p>Myra: This is who I really am, anyway. Just an ecentric kid who enjoys a quiet night of reading.Mark: If that’s how you put it, then I’m justa a weak-willed slacker who would skip school before exams to talk to a girl he barely knows.</p></blockquote><p>Despite all of that, I’d say it is a nice game for its free price tag, compared to another free VN with a pink hair girl, which is too short to have any kind of plot development. I think that game somehow shows how hard it is to make a good VN.</p><p>If you play the game, remember: do not genuflect.</p><h2 id="Some-Discursion">Some Discursion</h2><p>After that I played some Unity-chan shooting. It’s some pixel danmaku shooting game made with Unity. The group later made another game named <em><a href="https://play.google.com/store/apps/details?id=jp.tank.ezdaemon.ots">SOUND SHOOTING!!!</a></em> which combines the shooting part with a little rhythm game elements. You can see the similarity in their UI or fights at a glance.</p><h2 id="Stellaren">Stellaren</h2><p>There is one nice free VN called Stellaren. Space opera might be the word to describe it. No. Space visual novel it is.</p><p>I can’t recall almost everything about every game I played more than three years ago. For games I played even back, even for games like <em>Irodoritori no Sekai</em>, one of the first visual novels I played and loved, in like 2012 or 2013.</p><p>So there’s M, the protagonist, with N, his childhood friend, runs away from a colony and into a ship, or army? led by C, and then served there as a fixer, or say mechanic. Later M gets caught by the opposing clan, but eventually gets in good terms with the commander V, who is a little yandere. After that a lot happened and all of them have to get together to fend off some alien with advanced technology, and finally boom, the end. That’s what I can recall from the whole game, although the game itself is really long — prolly tens of hours.</p><p>This one is really lengthy, and in my opinions, more like a typical visual novel. By typical I mean more things you would expect from a lightnovel or anime in 2000s, harem, tsundere, that kind of things. What I enjoyed most was probably the fight where you control a shuttle to shoot enemies down in space. I never skipped a single fight because I want to see a 9/9 or 10/10 at the end of a chapter. However, the difficulty cranked up near the end-game and I was a bit bored dying at the same stage. I remember myself, lying in bed, phone in hand, steering my fighter through the barrage of asteroids.</p><p>I played the original version, but it seems the author just put everything together and put some ads in it. It is find for me to replay Lily’s and Sepia Tears, but for a game as long as Stellaren, I fear I do not have the time to enjoy the space odessey. But that being said, Stellaren is a nice game, and it feels good to finish a long one like this. You know, that feel when you come home after a long journey, just like that.</p><h2 id="The-Dandelion-Girl-Don’t-You-Remember-Me">The Dandelion Girl: Don’t You Remember Me?</h2><p>It is a visual novel adapted from the sci-fi novel of the same name(just The Dandelion Girl, without the subtitle). Not one you could find in the play store since it’s a PC game, but it’s available for free on Steam. If you know Clannad the game, not the band, and have a little curiosity to do some research, you might know this. That is how I ran into it, and that was a day in December, 2017.</p><p>I found the game from a well-dated post in a little forum which I can’t name right now(if I knew that game was already on Steam since 2016, I could have had much less trouble; probably Valve wasn’t paying much to make its games to the top of the searches those days). The author decided to give it a remake, but since they cannot get the guy who draw the things to do it, they were a bit limited to what they can do. Despite that the remake was done, and it adds some more texts to the original version, including the subtitle. Yes the original game does not ask whether you remember me.</p><p>I remembered that I opened the game(after dealing with Wine stuff as most Linux users do), saw the girl’s appearance, with the weird feel of her eyes when she turned back, then immediately decided to read the novel instead. I’m truly sorry.</p><p>Going through the game again I would say it is a nice plot — anyway, how bad can it be when the plot is good? And the game differs from the novel a bit: there are some minor differences in languages and plots that makes the VN more like a VN, and the novel more like a novel. So nothing feels so out of place for me.</p><p>It’s quite short — takes half a hour. And hope you enjoy the time in a summer’s afternoon, on a hill, with dandelions, that passed down from 1961 to 2016.</p><h2 id="Coda">Coda</h2><p>There are other free games I already made a post for, like DDLC and Tetra, they are great games but which I played much more recently, so I left them out. A search will lead you to the posts.</p><p>Sometimes I stop and look back into my past. What I did, the friends I had, all sorts of thing. And when I do this, I feel being myself. 'Sides, it makes me really happy to see I still like the things I liked.</p><p>And please allow me to end this little memoria with some words in <em>The Dandelion Girl: Don’t You Remember Me?</em>, that has a little change to the repped line in the novel.</p><blockquote><p>“Oh, oh! You know, the day before yesterday I saw a rabbit, and yesterday a deer, and today, you.”</p><p>“And here I was taking it all for granted, I’ll have to stop by more often.”</p></blockquote>]]></content>

        <content type="html"><![CDATA[<p>喜欢缪可的人通称缪客。大家都是缪客。</p><p>好吧，不是所有人，但是学校里的很多人，我认识的，我不认识的，都喜欢缪可。如果放学后有看到一群人围成一圈，像是在举行神秘仪式的邪教徒一样，那准保是在缪可。有的人喜欢缪可之甚，会在上课偷偷摸摸地缪可，被老师发现叫到后面罚站（现在这个时代肯定不能随便叫学生罚站了）。我们学校甚至有缪可社，不少学生都有加入，他们会隔一个周末，在学校的足球场上举办大型缪可，学生们围成的圈有时候会特别大，大到跑道上。不过有的学生不喜欢大规模的活动（比如我就只会做到放学经过社办门口进去看一看的程度）。所以足球场上的盛景，也是一位缪友告诉我的。</p><p>我不太想说，但是有人喜欢自然有人无感，甚至反感。二狗（他说他家里人也管他这么叫，不仅因为他是老二，而且是狗年出生）大概就是其中一位。他就不是很喜欢随大流，他的一句口头禅就是“干嘛学那些人”。我觉得这可能跟他有个优秀的哥哥有关，虽然二狗从来不跟我们过多提这个哥哥。</p><p>我问过他：“二狗试试缪可吗？”</p><p>他顿了一下，摇了摇头，“最近太忙了，没时间”。我也就没再问过他了。</p><p>或许是知道缪可在学校里的人气，学校外面的街角那里，最近还有立缪可的广告牌，特别大的一张喷绘布。广告牌里的明星我虽然不熟悉，但是不得不说，她缪可的样子确实有点酷。</p><p>所以今天，我以为也是上上课，课间和朋友聊天的时候提到几句缪可，放学之后稍微缪可一下，这样平凡的一天。我错了。</p><hr><p>早上我看群里的消息，都是在讨论这个：缪可公司出了一个大丑闻。因为没有主流媒体报道，我只能从各个地方流传的消息里翻出个一二。虽然我自己对这类丑闻无所谓，但我大概知道，缪可完了。</p><p>不过我来到教室后，见到的又是另一番生龙活虎的景象：同学们或多或少都在讨论缪可，连一些就我所知从不缪可的人也加入了讨论。</p><p>“唉，缪可是挺好的，可惜被这个公司给毁了。”</p><p>“虽然我不是缪客，但是整这么一出，确实是要完了。”</p><p>“门口的那个广告牌估计要被砸了。”</p><p>我不忍心加入讨论，便拿出书来看，不过关于缪可的声音还是不断地传进我的耳朵。我只好装睡，用胳膊挡住耳朵直到上课铃响。</p><p>下课时，有些不缪可的人也会问我一句对这件事的看法，我回道，我能有什么看法，缪可要玩了呗。他们听到便嗤笑一声，继续聊别的了。有人在教室里对那位被罚站的同学大喊一句“今天还在课上缪可吗”，然后一阵哄笑。那位同学只是摇摇头，没说话。</p><p>放学后，本来司空见惯的缪可小团体也不见了。我经过缪可社办的时候，发现社办的牌子已经被卸下来，房间里不同寻常地冷清，偌大的房间里只有两个同学，一位在写作业，另一个在看手机，两个人我都有点印象。我问社团怎么了，看手机的同学抬了头望了我一眼，说：“决定解散了。”是嘛，我回答道，然后默默地离开。这是我最后一次进缪可社的房间。</p><p>路过街角，那个缪可的广告牌被人砸破了。破洞的位置大致在那位明星的脸附近。周围围了一圈人，有的人说“草”，有的人在拍照。我加快了脚步，想要把这个景象扔在脑后。</p><p>我知道从今天起，没有人敢在白天缪可了。</p><p>晚上在床上辗转反侧，理性告诉我，别去想缪可的事了，但是我就是止不住地去想，一旦想到，就止不住地难过。我问自己：“缪可本来不该是给人带来快乐的事情吗？为什么我现在这么难过？”</p><p>我笑了。我决定忘了它。</p><hr><p>几天之后，再去缪可社的时候，大门已经紧锁，门上贴着一张纸：</p><p>“虽然我们是喜爱缪可的一群人，但是我们无法容忍缪可公司的所作所为。所以我们决定，在缪可公司给出回复并作出道歉之前，无限期停止缪可社的活动。缪可社”</p><p>街角那个被打烂了脸的广告牌，第二天也拆了，只留下空空的铁架子。广告牌上的明星公开道歉，并宣布停止与缪可公司的一切合作。</p><p>二狗有问我：“最近还在缪可吗。”</p><p>我回答道：“没了。”</p><p>“哦。”他说道。然后他就没再问过我了。</p>]]></content>

        <content type="html"><![CDATA[<h2 id="2019">#2019</h2><p>她站在跑道上，望着晚霞点缀着的海面。</p><p>我远远地望着她，揣摩着。她到底在看些什么，又在想些什么呢。是把海面看作是浩渺的宇宙，粼粼的波光当作是将抵的舰队？抑或是遥望海的另一端的本土，思念着许久不见的家人……和恋人呢？</p><p>再次遇到她，是在来到这艘航母之后的事了。当然我没有大模大样地问她在来这之前是否有恋人，以免打草惊蛇。不过就我的推断，开朗积极如她，赢得一段感情应当是不在话下。</p><p>一阵晚风袭来，我不禁打了个寒颤。她不冷么。不过即便如此，她依旧一动不动地站在那里，但不知为何，看起来更加遥远了。</p><p>这次，我没有跟她说上话。</p><p>2018年，未知外星文明入侵。</p><p>2020年，人类灭绝。</p><span id="more"></span><h2 id="2010">#2010</h2><p>星期六的下午。</p><p>老实说，我不是那么讨厌学习，但是我也不是那么喜欢课外班。考试本应该是比较受到同等教育的学生的学习成果的行为，课外班、补习班的存在打破了这一平衡，也打破了学生们投入到素质教育的时间的上限。通过放假时间上课来获取更加优秀的成绩，我认为这是一种恶性竞争。</p><p>好事是这种恶性竞争几年后就会被明令禁止。我不禁嫉妒起未来的小弟弟小妹妹们，他们可以傻乎乎地在这烈日之下自由地奔跑嬉戏、中暑晕倒。我摇了摇头，摆脱开这一想法。</p><p>10 年后的日子像鬼魂一样，曾时不时在我眼前出现。那段时间，我感觉自己像失去了灵魂的躯壳一样，浑浑噩噩，终日不知所措。对未来一无所知的人们反而成了我羡慕的对象。那种感觉过了一个月才渐渐消退。不如说，我学会了转移焦点。取而代之的是及时行乐的想法，与其忧虑注定到来的末日，还不如珍惜当下，多享受一番。</p><p>按照这个逻辑，我现在应该是在室内一边吹着空调，一边打着游戏的。我之所以冒着烈日来参加这个课外班，一个原因是家里没有游戏可以打，另一个原因则是这里有她在。</p><p>她——连雪是我的小学同学。她平易近人，虽然有点别扭，容貌——按照小学生的标准——算是不错的，而且成绩向来优秀。在除了成绩，就几乎没有什么好比的小学生眼里，她自然而然就成为了憧憬的对象，还是个小屁孩的我当然也包括在内。我的成绩？现在的话，算是不错啦。</p><p>闲话休提。可能是觉得难以接近的原因吧，虽然是同学，小时候的我却没怎么和她有过交集。对此我有那么一丁点，那么一丁点后悔：跟她的关系要是再好一点，就好了。不过对于过去的自己而言只可远观的她，对于现在的我来说，是不是就是容易接近的对象了呢？抱着这样的希望，我想着至少圆一下过去的遗憾，就这样来到了课外班所在的大楼。</p><p>这是一栋写字楼，接待处的大姐姐看到我脖子上挂着的名牌，便没有说什么。教室在6楼——我走进电梯，按下按钮。当门将要关闭的时候，我看到另外一个挂着名牌的身影正向电梯这里跑来。是她。我的心跳快了一拍，连忙按下开门按钮。她跑了进来，看到了我，便转向了电梯门，没有说话——。我从面板处退了一步，留出空间。巧也不巧，一个男人在电梯门再次关上之前，也跟了进来。男人按了5楼。</p><p>我瞥了她一眼，她像是在沉思，没有注意到我。5楼到了，男人走了出去，她突然也跟着走了出去。我叫住了她。“教室在6楼！”并按住开门键。她张望了一圈，听到我出声喊她，又走了回来。电梯门关上了。“走神了。”她小声说了一句。然后就没有再说话了，像是一副不高兴的样子，可能是因为出丑的缘故吧。</p><hr><p>下课后。看着一个人收拾书包的她，我不知从哪里涌上了勇气。我追上了她，问道，“一起回去吗？”</p><p>毕竟有一段是顺路，我心里在给自己找借口。</p><p>她瞅了我一眼。“随便。”漫不经心地回答道。</p><p>我们走在大楼和行道树的阴影之间。热气让我呼吸困难，知了在汽车的呼啸声中肆意聒噪。我莫名地想吃冰淇淋。香草味的大杯装。</p><p>“好热啊。”我像是在对自己说。她没有回应，像不觉得热似的。</p><p>一个拐弯之后，是一个长长的下坡。路面被太阳晒得发热，路两边稀疏地种着树， 在人行道上洒下零零落落的树荫。路上人影稀疏， 偶有汽车经过。我们一边聊着关于课外班的话题一边下坡。</p><p>下了坡，穿过一个小公园。公园里没有人。小公园没有滑梯和秋千，不过有一个沙坑。一座城堡矗立在那里。我下意识地走到沙城堡前。我突然有一种奇怪的感觉：这个沙堡将要融化，像初春的雪一样，变回沙子，落进池里。魔法的时间就要结束了。</p><p>连雪走在前面， 我跟在后面。快到她家门口的时候，她停下脚步，转过身来。</p><p>“今天过得很愉快。”她说道，脸上露出笑容。不像是平常的她的笑容。</p><p>“我也——”</p><p>钝器打击的声音。</p><p>我的意识就此中断。</p>]]></content>

      <title>Reality can never imprison Dreams — Tetra World Adventure</title>
      <link href="/posts/tetra/"/>
      <url>/posts/tetra/</url>
      
        <content type="html"><![CDATA[<p>Tetra World Adventure is a puzzle game by <a href="https://twitter.com/bloom_mushroom">Bloom Mushroom</a>. Recently an enhanced version of it made its way to Nintendo Switch, but the mobile version has been around, free of charge. Since the Switch version is only available in Japanese store, I played the iOS version instead. It’s not that I don’t have the money to buy it. No. Not even close. I want to emphasize it is not the case.</p><p>It’s a short puzzle game with moderate difficulty. I’m no expert in puzzle games, and without hints this game took me 2 hours to beat. If you are looking for a nice and relaxing otherworldly adventure, feel free to pick up this game. For free.</p><span id="more"></span><h2 id="A-Little-Discursion">A Little Discursion</h2><p>By the way, it took me some effort to find out the maker of the game. Appstore says the developer is norihiro hanazono, but a search of it leads me to some game news site instead of the author themself. Then I opened the in-game credits, only to be surprised that the author is not there. When I was about to give up, I noticed the signpost in main menu, which was like</p><figure class="highlight plaintext"><table><tr><td class="code"><pre><span class="line">-----------</span><br><span class="line">|Bloom App|</span><br><span class="line">|mash room|</span><br><span class="line">-----------</span><br></pre></td></tr></table></figure><p>The mysterious text struck me with awe. Google says Bloom is the name of an app that helps you sleep and meditate, and another app that helps you create melodies by tapping circles. But the link between mindfulness, circles and this little puzzle game is yet unknown.</p><p>Also I was wondering what a “mash room” is for. Maybe it’s a little room in a factory downtown. Workers are streaming in and out with wood bats over their shoulders. They mash things there: they mash potatoes, tomatoes, and radios. The mash is made into salads and sold countrywide. The first line the workers say when picking up a phone is “mash mash”.</p><p>Anyway, this led me to the author’s twitter, and I linked it above.</p><h2 id="Plots-and-Mechanics">Plots and Mechanics</h2><p>The game is a point-and-click adventure. Each door in the main menu represents a stage, and in each stage, you travel between rooms, grab tools and items to solve the puzzle.</p><div class="figure fig-33" style="width:;"><a class="fancybox" href="https://res.cloudinary.com/noirgif/image/upload/v1597352345/tetra_aytkmv.png" title="Image from Google Play" data-caption="Image from Google Play" data-fancybox="default"><img class="fig-img" src="https://res.cloudinary.com/noirgif/image/upload/v1597352345/tetra_aytkmv.png" alt="Image from Google Play"></a><span class="caption">Image from Google Play</span></div> <p>This game doesn’t have a lot of items, and they don’t interact with each other. And the main difficulty comes from inputting the code. The player should look around carefully for clues that corresponds.</p><p>For example, in the beginning of the game, the player has to solve a puzzle made up of five sliders. Each slider has two states: up or down. And in the same room, we find out that the fish hanging on the wall has exactly five bones pointing up and down, and entering their direction solves the puzzle.</p><p>As the player ascended to the top of the tower, there’s a girl quietly standing there, writing in a book. It turns out this magical world is the girl’s creation. Her vivid dreams.</p><p>As the player progress through the game,  puzzles become more and more complex. In a stage, the player needs to enter three code correctly to obtain a key. In another stage, they need to count fishes of each type, and multiply the counts by their price to get the final result. Some earlier puzzles may come back, but with a twist. Take the fish bone puzzle in World 1 for example, it comes back in World 4. However, unlike in World 1, the number of bones exceeds the digit of the code. Therefore the player must find out which bones are related to the code, and which are not.</p><p>When the player finishes World 4, expecting to find the girl, what greets them is her sudden disappearance. And the story behind the story slowly reveals. I will save the fun for the play here. But be prepared for the story that carries a tinge of sadness. If you’ve listened to Prisoner / Paperplane(a series of vocaloid songs), you will feel familiar with the plot.</p><h2 id="The-End">The End</h2><p>I’ve always wanted to be lost in imagination. The azure sky. The tall grass. The ray of sunshine. A shelter from reality. However, as time goes, I find my self getting lost in everyday sundries, in sensual excitements — I am losing my self in reality. Just like a breeze flowing through the wind bell. Tetra reminds me of that. I felt myself liberated, like the bird, flapping its wings, to the end of the sky.</p><p>Thanks Bloom Mushroom for the fantastic journey. And if you read this article and enjoyed the game, it is my highest pleasure.</p><p>Edit: I played the slide princess by the same author, and that is also a nice puzzle game with some secrets and suprises.</p>]]></content>

      <title>心脏和人偶 —— 心臓と絡繰</title>
      <link href="/posts/shinzou-to-karakuri/"/>
      <url>/posts/shinzou-to-karakuri/</url>
      
        <content type="html"><![CDATA[<p>这是一首 Kanzaki Iori 作曲作词，花谱（Kaf，花譜）演唱的曲子。 Kanzaki Iori （原名是全用片假名的），就是那个，那个 vocaloid P主，那首《被生命所厌恶。》（命に嫌われている。）</p><p>《被生命所厌恶。》针对的是一种轻视生命的行为，一种表面上重视、实际上却拿生命在开玩笑的行为。轻视生命的我们“被生命本身所厌恶”。唱着无论如何也要活下去，忍耐着、挣扎着、笑着、背负着活下去。这样的歌。因为歌词十分直白，所以比较好懂。</p><p>写这篇的理由是因为感觉我听的日语歌里，各种修饰性的语言频发，有点像村上春树的小说，有点让人抓不住头脑。所以如果，。这次想要介绍的《心脏和人偶》，虽然不是像《被生命所厌恶。》那么直白，但也是挺好懂的一首歌，当作起手式可能正好。我不是职业的音乐人，也做不出高深的分析，也不敢自称说的都是对的，再怎么说，这也只是我个人的理解。但如果这篇文章能让读者对这首歌本身、Kanzaki、抑或是花谱感到一点点兴趣，那就是我的荣幸。</p><span id="more"></span><h2 id="原曲PV">原曲PV</h2><iframe width="560" height="315" src="https://www.youtube.com/embed/hcm1LGOxJbc" frameborder="0" allow="accelerometer; autoplay; encrypted-media; gyroscope; picture-in-picture" allowfullscreen></iframe><p>（也放上播放数比较少的 <a href="https://www.bilibili.com/video/BV1cJ41187UD">B 站版本</a>）</p><p>花谱的PV通常都是正方形的画面，或许这和经常需要给花谱一个肖像有关。在这一点上，用方形画面也许比用 4:3 ， 16:9 的更好。另一方面，由于PV经常出现的是花谱在一些实景——地下通道、交叉口、公园等等，用方形的画面，或者更进一步， 3:4 的画面，应该能更让人想象这是用手机拍下的影像。这样，更有一种贴近观众的感觉。毕竟花谱算是虚拟偶像，贴近显示屏这一端的人，对虚拟偶像来说算是一种感觉上的加分点吧。</p><p>闲话休提，进入正题。</p><h2 id="这首歌在说些什么？">这首歌在说些什么？</h2><p>我们从歌曲名开始。毕竟歌曲名不是白起的，曲名往往提示了整首歌的主题，就像文章的标题一样。<del>虽然我上篇文章的标题和内容毫无关系。</del></p><p>人偶，这里日语原文是絡繰，指由机关驱动的装置。其实本身并不特指机关人偶，而是泛指日本那个时代的所有的用类似原理驱动的装置。但是这里是在描述人，所以为了方便，我就直接用人偶代称。如果看完 MV ，脑海里能浮现发条人偶的模样的花谱，应该就差不多了，233。</p><p>心脏应该也不是指字面上的器官，而是代指人的感情。按照我们现有的只是，大脑才是思考和感情产生的器官，但是奇妙的是，在说话的时候，大脑往往和人的智力联系起来，而心脏成为了人的感情的代名词：“没有脑子”被用来形容人愚笨，而“没有心”则是在形容人冷血。不过汉语里，不仅是心，很多其他器官——肝、胆、肠、肺——也具有象征意义。</p><p>人偶当然不可能有感情——它只会按照固定的模式行动。所以读到这里，就可以大胆猜想这首歌可能是在说人偶怎么没有感情，也可能是在说人偶怎么获得感情。</p><p>这首歌描述的是后者。让我想起类似的有一首歌叫《Near》（日语原名 ニア），是人类将近灭亡的背景下，一个人不停地向机器人 Near 问问题，直到自己生命的最后一天，的故事。</p><p>那知道了这首歌的主体，我不免想，换一个名字怎么样？</p><p>不用心脏(shinzo)，只说心(kokoro)，怎么样。不用机关人偶（karakuri），而用提线人偶、机器人，怎么样。</p><p>感觉上，用心脏两个字能够和人偶对称，但语言上的对称其实不明显：心脏和人偶都是4个假名；心脏是音读，人偶是训读。改成心和人偶，好像也没有什么大的差别。</p><p>机关人偶的话，很久很久以前有一个叫 40mP 的 vocaloid P主（这是这篇文章提到过的第二个 vocaloid P主）创作过一首名叫《活动小丑》的歌。歌曲名直译就是机关小丑。不过，《活动小丑》比喻自己被耍的团团转，来表达失恋时的痛苦。机关人偶，既比提线的主动——只要有能量输入就可以自行运动而不是靠人去操控，又不如机器人自由——固定的，没法学习。不如说现在的机器人越来越万能了，直接说机器人会给人一种十分聪明的人形机器人的印象。在这种意义上，机关人偶应该算是比较合适了。</p><p>刚才忘了说，这里的机关人偶，可以算作是 automata。（是不是想起了某部机器人拥有了感情、并寻找自己存在意义的游戏？ ）从这种含义上说，可以与人偶互换，从平衡上来说，应该不行—— automata 片假名写出来要占五个全角字符。</p><p>从题目确立了主旨，歌词就应该围绕这个题目解析。</p><h2 id="歌词">歌词</h2><blockquote><p>優しさも仕草も何もかも嘘でも</p><p>思うように信じたものを選ぼう</p></blockquote><p><em>就算温柔和举止都只是欺骗人的谎言，也要选择自己相信的事物。</em></p><p>上来就大打抽象牌，让人很崩溃，但是这句话过去之后就好很多了。大概。</p><p>首先，温柔的行为和举止的主体是谁，客体是谁？客体应该是“我”，即人偶；那主体理应是别人。那上半句话就可以翻译成：即使别人温柔待我是出于谎言而不是真心。</p><p>这里应该是感叹人的表里不一。不过，会压抑自己，才是理智的、像人的表现。理所当然地，“我”无法理解这种像人的表现，毕竟是人偶。</p><p>与怀疑相对应的就是相信。选择自己相信的东西，是不是指成为人呢，就不得而知了。</p><hr><blockquote><p>戸惑いだって有るよ</p><p>それでも教えてよ</p><p>この雨の解答を見せて</p></blockquote><p><em>也是有困惑的事的，即便如此也教会我吧，给我看这场雨的答案。</em></p><p>我错了，并没有好很多。</p><p>谁会困惑？“我”。润色一下就是：“我”虽然是“人偶”，但我也会困惑。だって表示列举，表示困惑只是“我”仍有的感情中的一种。</p><p>但是这样一来，之后突如其来的转折让我很困惑。祈使句的句式能告诉我们一些信息：谁教？“你”。教谁？“我”。教什么？下文“雨的答案”。</p><p>雨的答案是什么先放一边。按照常理，我有疑问，给我解惑，这两件事应该是自然而然的关系，而不是转折关系。相反的情况才应该是转折：我没有什么好疑惑的，但是还是教给我这场雨的答案吧。</p><p>仔细一想，这句应该是说：虽然“我”无法理解你所说的东西（因为是人偶），但我还是想听你告诉我这场雨的答案。</p><p>这场雨的答案是什么？千言万语化作三个字：不知道。我唯一知道的是，“雨”可以换成其他任何现象，彩虹、风、海浪、钟声。什么都可以，因为雨并不是特指什么东西。问题不是什么实在的问题的话，答案也自然不是什么实在的事物。比如，雨的答案并不是大气中的水蒸汽遇冷凝结成水滴当气流承受不住水滴的重量的时候就会落至地面。既然需要别人来教，那“我”肯定不懂，不懂的东西才需要教。</p><p>什么东西“我”不懂？人。因为“我”是人偶。所以这里表面是在说某种自然现象，实际上应该是代指人的、社会的某种行为，或者是从“人”的角度的对某种事物的理解和想法。</p><hr><blockquote><p>嵌めては崩してを繰り返して</p></blockquote><p><em>重复着放入和打散</em></p><p>这里和B段的“无法契合的拼图”相对应，都应该是把什么东西比作拼图。这里指在重复地拼入和打散。既然在重复打散，就说明“我”不会拼这个拼图。什么“我”不会的东西被比作了拼图？应该是和上文雨的解答一样的东西。</p><hr><blockquote><p>この傷もこの涙も</p><p>この気持ちは全部私のものだ</p></blockquote><p><em>这道伤痕，这些眼泪，这种感觉，都属于我自己</em></p><p>高潮部分的高潮部分。我感觉很难说清楚，就靠感觉吧。</p><hr><blockquote><p>少ない脳で答えを知った</p><p>仕掛けられた罠に揺れ動いた戸惑いも繰り返し</p><p>恋をしてみよう</p><p>君の優しさの全てが嬉しかったんだ</p></blockquote><p><em>用我愚笨的脑子得到了答案，在被设下的陷阱中摇动，反复困惑之后，尝试去恋爱吧。你温柔的一切都让我喜悦万分</em></p><p>第二局是在形容“我”挣扎着想要摆脱陷阱，具体动作可以翻译成摇动、晃动、抖动。</p><p>“我”笨，这个不用说。“我”是“人偶”，有很多不理解的事情。知道答案了，可能在照应上文“雨的答案”，知道这个答案，就等于“我”离“人”又近了一步。</p><p>但这里的“陷阱”是什么？这是我认为歌中数一数二抽象的地方了。</p><p>kotobank 上说：陷阱是用于捕获鸟兽和鱼的装置。比如用饵诱入笼中，或者用落穴困住，等等。另外，落穴中可能也有刺。所以总结一下，陷阱有两个特点：1. 困住猎物，这是最主要的功能；2.伤害猎物，使其无法逃脱，有的陷阱是这样。所以我深陷陷阱，应该是指我处于某种难以摆脱的、不方便甚至是有害的状态下。周围的人都谎言以对，可以说是陷阱；不懂人心，也可以说是陷阱。</p><p>其次，得到答案和挣脱陷阱并列，说明这两个动作有关联。从某种程度上，这也说明不懂“人心”的状态约等于在陷阱中的状态。</p><p>顺便一提，第二段高潮段也提到了陷阱。我们姑且认为全文所指的陷阱都是同一个陷阱。第二段高潮段关于陷阱的描述是：</p><blockquote><p>仕掛けられた罠を振りほどいたその先に</p><p>呆れ顔の君が待っていた</p></blockquote><p><em>摆脱了被设下的陷阱之后，有满脸惊讶的你在等着</em></p><p>由此可见，整首歌歌唱的是“我”摆脱陷阱的过程。也可以说是“我”获得感情的过程。</p><p>所以，“尝试去恋爱吧”，是不是像白雪公主的故事一样，有种恋爱使人从麻木中醒来的美好愿望呢？</p><hr><p>间奏。</p><p>MV 里花谱在公园里流连。</p><p>我最近有印象的是将近两年前，在芝加哥逗留期间去过的一个叫 spruce park 的公园。公园没有什么人，秋千，滑梯就静静地躺在树荫下，铺着树皮碎屑的地面上。我坐上去摇晃了几下。</p><p>之后突然发现告示牌上写着只许儿童坐，于是我赶紧四周张望，确认没有人看这边，才重新坐了上去。又摇晃了几下，才满意地走了。</p><hr><blockquote><p>後悔や痛みの夜を何度明かして</p><p>当たり前になったのは君のこと</p><p>罠だらけの日々を歩けない私の</p><p>手を引いて歩く横顔</p></blockquote><p><em>经过多少次充满后悔与痛楚的夜晚，你的存在已经成为理所当然</em></p><p><em>在陷阱四布的每日中无法前进的我，拉着我的手前进的侧脸</em></p><p>第二段着重描绘“你”怎么带着我走出困境，这也是“我”恋爱的一个理由吧。首先，“你”陪伴我渡过多少痛苦的夜晚。其次，“你”拉着我的手在陷阱中前进。</p><p>“理所当然”听起来有点像把“你”当作是一个工具人了，不过换个说法，就是没想过不存在的可能。对，一定是这样。</p><hr><blockquote><p>ぶつかり合って重ならないパズルが</p><p>最後のピースをやっと見つけた</p></blockquote><p><em>互相冲突，无法堆叠的拼图</em></p><p><em>终于找到了最后的一块</em></p><p>这里用的是 puzzle ，指谜题，或者是解谜的玩具。形式上，可以是拼图，也可以是积木。这里要叠的话，或许更接近积木。</p><p>具体含义是：本来没法拼的积木，在“你”的帮助下，终于找到了最后一块。</p><p>积木是什么？由主题来推断，积木是雨的答案，是心脏，是让人偶成为真正的人的关键。它的最后一块，就是爱。</p><p>如果玩过《魔女之泉3》，就知道这部游戏里也出现过类似的桥段：主人公本来是神创造出来的玩偶，为了成为其降临的容器。而这需要她获得各种感情，最后，当她获得爱的时候，作为一个容器才完整。</p><hr><blockquote><p>すれ違う心の奥底で</p><p>ずっと探してた優しさは</p><p>温りは何もかも全部君のものだ</p></blockquote><p><em>在彼此错过的心底里，一直在寻找的温柔、温暖、其他一切都属于你</em></p><p>すれ違う表示互相从对方的旁边通过，向不同的方向前进，或是各自的想法无法沟通。错过应该和上文的背叛和心碎相关（没有翻译）。也有可能是指“我”获得了自我，因此走上和“你”不同的道路。</p><p>我个人比较喜欢这种“细数回忆，那些最珍贵的都和你在一起”的感觉。</p><hr><p>摆脱了陷阱之后，就是深情的表白和誓言，“在这之后，我也想继续守护你”。</p><p>同时也表达了获得“心脏”的快乐：“你的一言一语和迷惑不解都使我万分喜悦。”</p><h2 id="这首歌为何而写？">这首歌为何而写？</h2><p>这里只是我的一些理解，就当作是茶余饭后的玩笑话，不用当真。</p><p>这是 Kaf 的第二首原创曲，作为主打唱歌的 vtuber，歌曲的内容也关系着歌手的形象。Kaf 在唱歌的时候十分投入，“真真正正把歌变成自己的”，对这样的 Kaf 来说，一首饱含感情的歌非常适合。</p><p>另外，vtuber 很大程度上也是在演绎一个角色——所谓设定。比如傲娇班长、女仆等等。通过《心臓と絡繰》，Kaf 或许是在像世界表达自己不是一个角色，而是一个有血有肉的人吧。</p>]]></content>

        <content type="html"><![CDATA[<p>虽然这个博客里的文章基本上都是凭兴趣写的，但是我也非常高兴有人来看。在这里我想讲解一下，我写了什么东西，抑或是为什么写的，如果这样能够增加各位读者的理解，或是对这些文章提起哪怕一丁点的兴趣，那也是我的荣幸。</p><p>梦日记并没有解说，这点就像《梦日记》一样。</p><span id="more"></span><h2 id="4-月-1-日吉日">4 月 1 日吉日</h2><p><a href="/posts/april-1st-is-a-good-day/">本文链接</a></p><p>三人成虎的典故大家都听说过，那么反过来是什么样子呢？当大家都不相信的时候，会不会使得本人也渐渐怀疑自己？这篇博客就是在讲述这样一个故事。</p><p>不过在故事里，还多了一个限制，就是魏莱是做梦梦见世界毁灭的，而梦里的记忆随着时间流逝在急速地消失。而到第二天，这份记忆就完全消失了。</p><p>#workshop，也就是《茸雪》（这里有一篇《茸雪》的（英文）随想，感兴趣的可以），《梦末》的开发，上个月出了系列的第三作《昙花》，但我才玩了前几章。《昙花》的主角也是一种患了奇妙的病，使得他非常健忘：生活、朋友、以及一切。他唯一印象深刻的是他在学校撞上的女主。后面……就不知道了。</p><p>吉日其实没有什么特殊含义。其实某种含义上每天都是黄道吉日，不过在吉日宣告世界毁灭，是不是有点突兀呢？如果有就好了。</p><h2 id="某一个冬日的下午">某一个冬日的下午</h2><p><a href="/posts/winter-afternoon/">本文链接</a></p><p>讲述了我为什么想喝热可可，又不想喝的故事。</p><h2 id="恋爱喜剧害死人">恋爱喜剧害死人</h2><p><a href="/posts/lovecome-kills/">本文链接</a></p><p>看恋爱喜剧轻小说的时候，会不会经常想：</p><p>这个女角也太好骗了吧。</p><p>又有新后宫了。</p><p>诸如此类。这是不是对人性的扭曲？对人权的侵害？如果是，那如果把主人公这一特异点去除，是不是就会解决问题？这篇博客就是在做这样的尝试。</p><h2 id="A-Paper-Plane-to-the-Past">A Paper Plane to the Past</h2><p><a href="/posts/paperplane">本文链接（英文）</a></p><p>其实是橘子班的《12色的季节》的随想。在游戏里，纸飞机成为了穿越时空的媒介，也让错过的男主和女主重新相会。</p><p>玩了游戏的读者，是否会感觉章节的顺序其实也是一种暗示？如果有类似的感觉那我会非常高兴。</p><h2 id="My-Story">My Story</h2><p><a href="/posts/my-story">本文链接（英文）</a></p><p>这一篇其实是《你的故事》评论的预告一样的文章，虽然《你的故事》的评论 4 个月之后才出。感觉 n-buna 的歌《白雪》给了这篇文章很大影响，不如说这篇文章像是在进行《白雪》里的心理描写。</p><p>这里也贴一个<a href="https://www.youtube.com/watch?v=oAVDdEfiy4o">原曲的链接</a>。</p><p>原曲是“我”在饮下毒药之前回忆起的，遇到的“你”的故事。“如果再努力一点去寻找你的话，是不是就能再踏出一步了呢。”在《你的故事》里面，也有类似的桥段。千寻从人群中看见久别的青梅竹马的脸庞，满心欢喜地前去寻觅，最后却是认错人。这一天下着暴雨。失意的他找到一个居酒屋，把自己灌醉。</p><p>如果听了这首歌，或是能够对《你的故事》有那么一点兴趣就好了。</p><h2 id="Last-Day">Last Day</h2><p><a href="/posts/last-day">本文链接（英文）</a></p><p>这一篇其实是《景之海的 Apeiria》的预告。我努力描绘主角零一最后前往边界之塔，去结束一切的场景。最后一日的标题由此而来。</p><p>因为打完游戏也是两年多以前的事情了，所以细节我只是依稀记得。但《景之海》可以说是我打的为数不多的黄油里剧情我非常喜欢的一部作品了。</p><p>时间的回溯是游戏里反复出现的一个因素——在每一条线里，零一要去解决女主人公的问题，而他的最终目标则是打倒观察者(Observer)，救回 Aperia，但前几次都因为某种原因而失败，导致时间回溯。从结构上来说，《景之海》非常类似《命运石之门》。</p><p>不过不像《命运石之门》的是，所有的悬念是在最后一口气解开，而且世界观其实也非常不同。</p><p>当你在窥视屏幕的时候，是否有一个人在屏幕之外观察着你？</p><p>虽然是我个人的品味（我比较喜欢有 meta 的作品），但是如果能引起共鸣那将是我的荣幸。</p><h2 id="Compile-Heart-Busted">Compile Heart, Busted</h2><p><a href="/posts/compileheart">本文链接（英文）</a></p><p>这是前年愚人节写的东西。那时候 Compile Heart 刚公布《勇者 Neptune（假定标题）》，将是一个由加拿大的工作室做的一个 2D RPG。</p><p>如果有哪位读者想玩——我也不拦就是了，毕竟我也没有玩。</p><h2 id="Memories-Off">Memories, Off</h2><p><a href="/posts/memory">本文链接（英文）</a></p><p>标题取自秋之回忆（告别回忆）系列。当时 MO8 中文版的众筹刚刚结束，而 PC 版直到今年 4 月才上 Steam，可以说是物是人非了。</p><p>主要联系了几部作品——《我在7年后等着你》（游戏），《图书迷宫》（轻小说）和什么来着。</p><p>和《我不知道的恋爱喜剧》（轻小说）。</p><p>《图书迷宫》是 meta 的集合体。主人公不知为何失去了记忆，他能记住的，就只有写在一本名叫《最后的祈愿》的笔记上写下的内容。他只能依靠这本笔记，和在图书迷宫中发现并同行的吸血鬼女王亚历山德莉亚（抱歉，但这确实不是女性名字，我尽力了），尝试解开 5 年之前，自己的父亲被杀的谜团。</p><p>而在《我不知道的恋爱喜剧》中，主人公拥有穿越时空的能力，他一穿越，突然就有辣妹女朋友了，再一穿越，又没了。这样的故事。</p><p>两部轻小说都是比较挑读者的类型，所以如果有碰巧喜欢这两本书的同好，我会非常高兴。</p><h2 id="虫子">虫子</h2><p><a href="/posts/worms">本文链接</a></p><p>不用想也知道，这是 DDLC/心跳文学部的预告。但内容，正如后面写的一样，是在描绘出汗后浑身瘙痒的感觉。</p><p>如果看过纱世里在文化节上发表的那首诗，就会明白为什么会变成这样了。</p><h2 id="一刀9999级的世界">一刀9999级的世界</h2><p><a href="/posts/9999-chicks-for-a-dollar">本文链接</a></p><p>这可能是这个博客里所有搞笑玩意的起点了。</p><p>一刀 9999 级，魔法适应性 9999。难道 9999 就是最大的数字了吗？</p><p>在有些游戏里会有满级。比如《怪物猎人：世界》，满级是 999 级。在《女神异闻录5》里，满级是 99 级。Undertale 里这个数是 20 。在这些游戏里，或许是。但用一个不是游戏脑的，一般人的大脑去思考，9999 明显不是极限。</p><p>有没有可能给玩家送 9999 级是骗人的，一进游戏一看，里面都是像点击游戏里一样用 aa bb cc dd ee 来标记的等级的怪物？</p><p>文内的场景来自于旷野之息，但我不清楚那时候我有没有玩过游戏。如果看这一篇文章能够让眼镜因为超高的战斗力而炸掉，那将是我的荣幸。</p>]]></content>

        <content type="html"><![CDATA[<p>20XX年4月1日吉日，魏莱从睡梦中惊起——他成为了一个有秘密的男人。</p><p>他伸手摸了摸被子——干的。他松了口气，为没有又增加了另外一个秘密而感到庆幸。但他随即意识到，现在不是放心的时候。</p><p>他从未来穿越到现在，而在未来，人类将迎来末日。</p><p>20XZ年，不明生物入侵地球。这种生物所过，寸草不生，而对人类来说，就算短暂的接触，也足以致命。几年以后，生物扩散至大半的地球。由于音讯不通，魏莱不知道其他地方的情况，但他所在的避难所只剩寥寥十数人。</p><p>但即使如此，人类也没放弃最后的希望——他们开发了能够将信息传送到过去的自己的装置，魏莱就是其实验者之一。</p><span id="more"></span><hr><p>魏莱自己也觉得这件事有些过于超现实。但鲜明的记忆让他不得不相信确有其事。</p><p>不清楚和一起发送超时空消息的人们都怎么样了，他想。他甚至不知道那些同伴现在都在哪里。在那时候，谈论过去的事与揭伤口无异。魏莱开始后悔了，当时他应该要一两个人的家庭住址的。</p><p>到学校去碰碰运气吧，魏莱看了下表，现在是还是凌晨，想了想，有充足的睡眠才有精力找人，他又躺下了。</p><hr><p>魏莱的好友金日找上了他。</p><p>“你知道吗？语文老师生病了，下节课自习！”金日洋洋得意地说道。或许是因为他们的语文老师作为班主任，经常带头占课；不过更有可能是因为金日昨天被叫到办公室臭训了一通，今天终于出了口恶气。</p><p>不过魏莱没放在心上，他在想他的那些同伴是不是会占领学校的广播站，用奇怪的摩斯电码，报导这一消息。</p><p>“你怎么啦？”直到金日在眼前摇晃手，他才回过神来。</p><p>“有件事跟你说，”魏莱抬起头。</p><p>“什么啊？”</p><p>“其实，人类就快濒临灭绝了。”</p><p>“哦。然后呢？”</p><p>“所以翘个一两节课也肯定没事。”</p><p>“哈哈，别当真，刚才骗你的。”</p><p>魏莱叫住了打算继续用这个把戏骗其他同学的金日。</p><p>“我是认真的，我有未来的记忆。”</p><p>魏莱大致讲述了本文第一节的内容。他没有提及被子是干的。</p><p>“我看你可能是做了一场梦，就当真了。你说的要是真的，要不试着联系联系那些同伴？如果你不是一个人回来的话。”金日叉起了腰。魏莱没有修正“回来”一词的用法。</p><p>“可我没有联系方式。”</p><p>“那你说什么。你去网上碰碰运气呗？搞不好他们也在找你呢。”</p><p>魏莱觉得有道理，午休时间偷偷摸进学校的机房，用午餐的时间，草草地写了一篇文章，放到了网上。</p><p>等他放学，饿着肚子又摸进机房看情况的时候，遗憾地，这篇文章没有一个人回应。大家或许都把这当成蹩脚的愚人节笑话了。</p><p>魏莱自己都开始觉得这事情有点不靠谱了。</p><p>魏莱觉得自己并不是那种好主动行动的人。他决定等同伴中的某个人上了新闻（他们肯定会这样联络自己），就去找他们。</p><p>“今天就先这样吧。”他对自己说。</p><hr><p>一觉醒来，魏莱感觉自己忘记了什么事情。</p><p>“妈，昨天是什么日子？”他不抱希望地问到。</p><p>“昨天？不知道。”</p><p>翻看自己家的老黄历，今天是4月2日，昨天是4月1日，宜祭祀。</p><p>“靠，昨天忘记恶搞了。”他想。</p>]]></content>

      <title>伊里野的，以及我的夏天</title>
      <link href="/posts/iriya/"/>
      <url>/posts/iriya/</url>
      
        <content type="html"><![CDATA[<h2 id="写在前面">写在前面</h2><p>《伊里野的天空、UFO的夏天》可以说是我比较喜欢的一部轻小说了，所以我个人希望阅读原作之后再回来看这篇博客。当然，没有看过原作对这篇博客内容的理解也不会有什么影响，所以我并不是在要挟。</p><p>日文原版在カクヨム上有连载，如果有日语基础的朋友推荐一试。</p><span id="more"></span><h2 id="夏天">夏天</h2><p>夏天的一个好处就是衣服可以穿的很少。而且可以游泳。虽然我是旱鸭子。</p><p>夏天已经过去了，我在戴着手套一边瑟瑟发抖一边打字。好不痛苦。</p><p>但如果现在还是夏天的话，做些什么好？</p><p>吃冰淇淋，画勾。</p><p>出去转转，画勾。</p><p>夏天！天空！大海！画勾，画勾，忘了。</p><p>然后我想做的事情就没了。我想挽留夏天，就好像留住了夏天，就留住了青春一样。有的时候做梦，也会梦到和高中、大学的同学在一起，做些有的没的。具体做些什么，却朦朦胧胧想不起来。</p><p>这时候，我遇到了《伊里野的天空，UFO的夏天》。</p><h2 id="梗概">梗概</h2><p>我其实也有在之前的博客里说过，我纠结于是写会有更多人看的书目介绍，还是写我想写的东西。我倾向于写一些个人的东西，书评的好处和坏处都是形式上过于客观了，所以看了一个书评，人们往往会有一种想法——这是对书的客观评价，但不是想这是一个人对书的主观体验。因此我还是会简要介绍这个系列，但是会在千人一面的介绍之间，穿插一些感想。</p><p><a href="https://zh.wikipedia.org/wiki/%E4%BC%8A%E9%87%8C%E9%87%8E%E7%9A%84%E5%A4%A9%E7%A9%BA%E3%80%81UFO%E7%9A%84%E5%A4%8F%E5%A4%A9">中文维基页面（先不要点）</a>很讨厌：它剧透了开头，剧透了结尾，就给人一种看完了整个系列的错觉。但我觉得，比起只看结局，更应该看到怎么一步步蓄势，升华，最后到达这样的结尾的。所以我自己来尝试介绍一下《伊里野》好了。</p><p>暑假最后一天的晚上，园原中学。浅羽直之从窝了一个半月的山上回来，除了各种各样山里生活用的行李以外什么都没有：别的地方没有去，暑假作业没有写，泳裤也没有带。浅野现在的心情，就和即将上刑场的死囚一样。</p><p>“还有13小时就会咣当，第二学期就会无情地开始了。理科老师、二年四班的班主任、35岁单身的河口泰藏，一定会让没交作业的学生们在讲台上排成一列，一面用科学的眼光怒视过来，一面科学地用出席簿吧当吧当敲每个人的头，一面要求科学地说明为什么连暑假作业都没法交的吧。”</p><p>决心及时行乐的浅羽，连自己没有带泳裤也不管了，晚上摸进中学准备偷游一番。没成想，泳池已经有先客了。</p><p>女孩子想学游泳，却迟迟不肯将脚伸进水中。浅羽费了九牛二虎之力才让她憋成气之后，一切都顺利了——一个小时不到，女孩子居然就能用浮板游了。</p><p>女孩子很奇怪：她不苟言笑，但兴奋起来就会流鼻血，而且最最不可思议的，还是埋在她手腕上的一对金属球。如果这也算还好的话，之后突然出现了一群黑衣人，说要送回家，浅羽遵从指令，上了面包车之后，就什么都不记得了。</p><p>“醒来之后，自己坐在家附近的公交站的座位上。衣服穿得好好的。本该停在录像带店的自行车也在。”浅羽想到这一个半月跟部长在深山里找UFO的经历。要么一切都是一场梦，要么自己是被外星人绑架了，浅羽想。</p><p>第二天开学，这个女孩堂堂出现在自己的教室，她竟然是转学生。她在黑板上写下的名字——伊里野加奈，怎么看怎么像伪名。她一定是外星人。</p><p>暑假结束了，但UFO的夏天还在继续。</p><h2 id="主题">主题</h2><p>以上就是第一卷第一章的梗概了。应该没什么剧透风险，没有。</p><p>“也太长了吧？”毕竟想解释标题中“UFO的夏天”，没有一些篇幅还是会显得比较突兀。想知道“伊里野的天空”是什么意思，就请看原著吧。:)</p><p>对我来说，《伊里野》不仅是典型的 boy meets girl 的故事，也是浅羽成长、改变的故事。这样的主题在很多小说里都能看见。放到《你的故事》（<a href="/posts/your-story">对应文章</a>，英文注意）里也是一样——浑浑噩噩，过去一片空白的天野千寻遇见夏凪灯花，失去夏凪灯花，在没有夏凪灯花的世界里继续负重前行的故事。还有很多作品——藤まる的《时薪300元的死神》、《明天，我将死去，你将复生》，佐野彻夜的《你在月夜里闪耀光芒》、《为这个世界献上i》……为什么一个作者经常写同一个类型的故事……具体浅羽是如何成长的，之后再提。</p><p>我无意多说世界系——我明白我说的再多，也只是复述自己从别的地方看来的东西，所以就简单的介绍一下，有兴趣的读者可以自行搜索其滥觞及变迁。</p><p>世界系这个词被用来形容有着类似背景、设定和描述风格的一些作品。世界系作品跳过社会，而将个人直接与世界联系起来：个人的举动会影响整个世界。在《伊里野》中，就有不明的外星生物入侵，人类只有黑蝠鲼(black manta) 这一战斗机能够抵御，而伊里野是唯一仅剩的黑蝠鲼的驾驶员；也就是说，她的乐意于否决定了人类的命运。除了《伊里野》，近期上映的天气之子也可以说是典型的世界系作品。</p><p>在此基础之上，作为21世纪初的小说，《伊里野》还在很大程度上受95年上映的《EVA》的影响：从大的角度上，世界的危机往往轻描淡写，而将镜头对准主人公的日常生活；从小的细节上，故事都发生在夏天，男主角都是弱受。</p><h2 id="小小杂感">小小杂感</h2><p>虽然浅羽是《伊里野》的主人公，但如果要问为什么浅羽平淡无奇的生活中为什么出来了一个UFO的夏天，那就不得不提园原中学新闻部部长水前寺了。</p><p>水前寺长得英俊，身高出众，成绩优秀，体育得意，惟一的缺点，就是他是一个怪人。这个怪人不喜欢女生、不喜欢交际、唯独喜欢研究超自然现象，并且每个季节就会换一个主题。在冬季，水前寺占领学校广播站，在上课时间做全校范围的ESP实验。而在春季，为了研究灵异现象，水前寺带着浅羽晚上跑到女厕所去调查是否幽灵出没；而到 6 月 24 日，当浅羽写好了关于校园灵异现象的文章准备发到社刊《园田电波新闻》的时候，迎接他的不是水前寺的赞许，却是一句：</p><p>「过时啦啊啊啊啊啊啊啊啊啊啊啊啊啊」</p><p>对水前寺来说，从 UFO 之日开始，灵异现象的春天早就结束，UFO的夏天就开始了。</p><p>即使这样，浅羽也毫无怨言，放弃了准备好的材料，默默地跟着水前寺跑到园田空军基地旁边的山上，找了一个暑假的UFO。</p><p>所以，当最后浅羽拒绝水前寺的时候，我知道他变得独立了。也知道，UFO的夏天，真真正正落下了它的帷幕。所以也用原文的这一小段，来做全文的总结吧。</p><h2 id="结语">结语</h2><p>“就算只有我一个，我也要继续做下去。”</p><p>“做——是指做麦田怪圈吧。”</p><p>“是”</p><p>“就算只有你一个”</p><p>“是”</p><p>“无论如何”</p><p>“是”</p><p>然后，水前寺笑了起来。每年每年，不少的女生都会被这笑容诳骗，做出把贵重的纸资源变成情书塞进水前寺的鞋箱里这种最愚蠢的行径。</p><p>“随你喜欢吧”</p><p>浅羽脸上也浮现起笑容。</p>]]></content>

        <content type="html"><![CDATA[<p>60分刚好，一分不多，一分不少。虽然有一种想把这句话当作座右铭的冲动，但是我明白对我来说，这充其量只是高考考了450的自嘲罢了。</p><p>网上翻了翻过去学校的分数线，在450附近的，感觉南阳理工学院还不错。学校录不少人，而且名字也好听。以后可以跟同学吹，自己是南阳理工的，反正他们十有八九也没听说过这个学校。</p><p>我躺在沙发上，幻想着多年以后高中同学会上的情形。六月下旬的太阳还是一如既往的毒辣，蝉还在外面聒噪，不过这都和在空调房里吃西瓜的我无关。</p><p>我今后的人生会不会就是进个60分的大学，找份60分的工作，过着60分的生活。其实也不赖，我想，只要不出意外的话。</p><p>正当我起身，去够茶几上的空调遥控器的时候，手机响了。</p><span id="more"></span><p>“您好，请问您是■ ■吗？”</p><p>是，我回答道。</p><p>接着电话告诉我我有一份 EMS 的信件，要我到楼下去拿。</p><p>我不知道送的是什么东西——最近半个月在网店上没买东西，618的活动页面上去转了一转，也没看到什么想买的。主要还是因为穷，穷限制了我的想象力。</p><p>我穿着拖鞋，一边咒骂着炎热的夏天和不能送上门的邮政，一边怀着对快递的期待，下了楼。</p><hr><p>当 EMS 的名字传入我的耳朵里的时候，我就该想到这是文件而不是新手机或者什么炫酷玩意儿了。抱着半放弃的心情望向扁扁的信封，上面写着“中国科学技术大学”，下面的地址是安徽合肥的一个地方。</p><p>我现在才知道这大学在合肥。</p><p>不，我现在才知道有这大学。清华北大是家喻户晓，复旦上交我也略有耳闻，这个中国科学什么大学真的从来没进过我的耳朵。为什么冠着中国名称的大学却在合肥，我也不清楚。上网一搜，什么985、C9，听起来好像挺厉害的样子。</p><p>回到家里，我四下找了找小刀，没找到。就用钥匙了。</p><p>总而言之，这是一封录取通知书。</p><p>读完后，第一感觉是可疑。985大学为什么会给我发录取信？我也没有参加自主招生之类的东西，为什么会提前发过来。</p><p>晚饭的时候跟父母说了这回事。于是他们给招生办打了个电话。“你好，我们家孩子收到了你们学校的通知信……”“■ ■”“嗯”“噢”“这样”“好的”，然后挂了电话。</p><p>“学校说这是一个特别的项目，邀请像你一样的学生参加。”</p><p>“反正就去呗，也不会差到哪里去。”</p><p>“总比去什么技校好吧。”</p><p>再差也不会沦落到什么技校吧。</p><hr><p>在火车上摇摇晃晃几小时后，又在公交车上摇摇晃晃半小时，终于到了学校的东区。马路这边是大门，那边是一家罗森，罗森好像在做什么活动，海报上画着一个卡通小女孩飘在空中，下面是炸鸡图片。</p><p>有点气势的长方形大门，走进一看，左半边拉着栅栏，只有右半边能进去，令人倍觉促狭。大概知道我是新生，门卫也没多问。</p><p>拖着行李又走了几步，感觉不太对。“这是什么味道？”我环顾周围，四下无人，只有蝉鸣。</p><p>丁字路口的地上有一个指路的海报，上面标了去往大礼堂的路：右拐，沿着路（这条路叫郭沫若路）一直往南就能看到了。路线简单点帮大忙了。</p><p>沿着郭沫若路又走了一会儿，路有点上坡，但走路没什么问题。</p><p>隐隐约约听到翻书的声音，越往前走，翻书的声音就越来越大。我突然感觉有点恐怖。我最终找到了声音的来源——一幢正面土红色的建筑物，像书本一样的东西从楼梯上方的门中喷涌而出。空气中的气味更加浓了。</p><p>这是什么鬼地方。</p><p>我有一种逃跑的冲动。</p><p>但好像有一种不可名状的的力量，拖着我的身体不由自主地往着书的冲积扇走去。我看向地上喷出的书，虽然书本不计其数，但是种类只有两种：电磁学千题解和——数学分析习题集。我感到一阵目眩。</p><p>“别动！”突然背后传来一声喊，没等我反应过来，我的手就被抓住了。</p><p>“快跑！”抓住我的手的人拉起我跑起来。行李被丢在原地。后来一合计，还好学校不给新生带电脑，不然就白给了。</p><p>当然跑的时候我没想这么多。顶多就是，她的头发飘到我脸上了，这种无关紧要的想法。</p><p>我们沿着来时的路往回跑，一路跑到了广场旁的一家白顶的小屋子才停下。推开玻璃门进去，我找了把椅子坐了下来。</p><p>“要不给你冲杯咖啡吧，边喝边说？”她看向柜台上的咖啡机。</p><p>看样子这是间咖啡店。</p>]]></content>

      <title>Free Will of a Marionette -- Let&#39;s talk about Tiny Snow</title>
      <link href="/posts/tinysnow/"/>
      <url>/posts/tinysnow/</url>
      
        <content type="html"><![CDATA[<h2 id="Intro">Intro</h2><p>A month or two ago, <a href="https://store.steampowered.com/app/1002560/Tiny_Snow/">this game</a> gained its fame through an unexpected way. In reply to an review criticizing the depiction being bad of how lovey dovey the duo are, the developer said: that’s because … well … I myself haven’t had a girlfriend.</p><p>Personally I feel a little sad for him. Although I might not be entitled to do so, since I am still single myself (fortunately I’m not too bothered by it). And also for his game. From now on when people talks about <em>Tiny Snow</em>, it will always be “that game made by the poor beta male” rather than “a kawaii game, but tries to cover some serious topics”, while the latter somehow better describe this game as a game.</p><span id="more"></span><h2 id="Plots">Plots</h2><blockquote><p>If you are made into loving someone, what will you do?</p></blockquote><p>The story starts with the protagonist, an assistant of the professor, how adopted him since he was young, running away to a shabby wooden house in a snowy mountain to focus on the research. However, little Rong<sup class="footnote-ref"><a href="#fn1" id="fnref1">[1]</a></sup>, his clingy sister, also an adopted child of the professor, followed him into this uninhabited place. The two of them both have a feeling for each other, and this feeling grows untampered as the two live together in this sequestered small hut.</p><p>However, the protagonist knows a secret, that he and his little sister are subjects of the professor’s experiment. In this experiment, they are made into thinking the each other is the best fit. And that’s what bugs the protagonist – choosing to be with little Rong means that he succumbs to manipulation.</p><p>But the choice has to be made. To accept it, or resist it.</p><h2 id="Are-We-Free">Are We Free?</h2><p>The existence of free will has long been discussed and debated about, somehow even until today. Some argue that we have free will, others disagree.</p><p>Determinism is such a belief that everything is predetermined, and thus free will does not exist. Ideas of determinism includes Laplace’s demon, an entity keeping track of everything and thus able to predict the future. But the demon is incompatible with Copenhagen’s interpretation, so hopefully it will stay within the realm of imaginary. Einstein was unhappy with this thought, because in his view, God doesn’t throw the dice.</p><p>However, there’s super-determinism, which states that everything is predetermined since the bigbang. This, unlike the demon, cannot be disproved. And this possibility can undermine the Bell test, which gained some popularity in 2016, and that’s another story.</p><p>That kind of gives out a feeling that, our behaviors may be predetermined – when we go to eat, what we think, the thought that we have a free will – and we could do nothing to change them.</p><p>But does that really matter? What is the point in upsetting ourselves for no one’s good? As long as things are good either way, it might be better to choose to believe in the one that we desire. For example, that we have free will.<sup class="footnote-ref"><a href="#fn2" id="fnref2">[2]</a></sup> It’s in a sense similar to Occam’s razor. But the objectives are different: Occam’s razor tries to make most people pleased, but this – I’d call it tiny snow principle, if I have the right to name it – favors ourselves than any other.</p><h2 id="Your-Love-or-the-True-Love">Your Love, or the True Love</h2><p>But the dilemma in the game is a little more complicated. The protagonist and little Rong underwent medications unconsciously, which make them believe that each other is the destined.</p><p>So is our free will still free under outside manipulations?</p><p>It reminds me of a biased classifier. Assume we train a binary classifier that, given a person’s health information, decides if they are infected with disease A. Suppose only an extreme minority, say 0.01%, has infected A, we will have a lot of negative cases, and insufficient positive ones. So the trained model can display biased behavior: it simply judges everyone as healthy, which is undesired.</p><p>A deeper analysis on its cause may be seen in a textbook and I won’t cover it here, but the point is, we have remedies for such unbalanced data. We can re-sample the data set to make it more balanced, or we can modify the output of the model to offset it. As long as we know it is biased, something can be done.</p><p><em>When we know we are not free, we are.</em></p><h2 id="Reality-and-Fiction">Reality and Fiction</h2><p>As the developer said himself, he hadn’t been in a relationship, which makes the lovey-dovey part less convincing. But there are things that based on facts.</p><p>In a part, the professor is accused of conducting this <em>unethical</em> experiment by her fellow professors, she reputes it by revealing that they are themselves corrupt. For example, a professor demands one of his students to call him “dad”, do daily chores for him, and witholds the student’s graduation. This may sound outrageous, but is something that actually happened. A graduate student was abused by his advisor in the mentioned way, and he committed suicide in the end.</p><p>Yes, the story is not full of sunshine, I forgot to mention. It’s more so in the small extra story “Xue” (lit. snow), where the female protagonist little Xue is assigned to a man who is psychologically disgusting, but physiologically alluring, due to the technology developed. She loathes the man so much, that when he talks, the only thing she heards is pig oinking. She tries to escape this nightmare, but the man wouldn’t let it happen. He captures her, rapes her in order to impregnate her and thus continue his lineage, which is the only thing in his mind. There is no love. If there’s anything, that would be hatred.</p><p>Back to the topic. The professor is depicted as someone who gives no shit about others’ opinion, and in a way prioritize the experiment over everything else, so it’s actually a bit hard to extrapolate her motivation to accuse her fellow workers of hypocrisy. That’s why I think this part is a bit contrived. Even if the author wants to discuss the dark side of the academia, which is a well-intended attempt to raise public attention, there may still be a better way for it to fit in the plots.</p><h2 id="Short-Review">Short Review</h2><p>I don’t rate any games, but I would say it is a <em>good</em> game. Not excellent, nor perfect, but anyway I’d like to recommend it.</p><p>Admittedly a lot needs improvement. For example, a significant part of the story is devoted to the professor’s discursive preach, meanwhile the reporter is, in most times, not regarded as a real person with emotions and feelings, but only a tool to advance this preach.</p><p>These shortcomings apart, Tiny Snow’s story surrounds an interesting as well as thought-provoking topic. This material vs mental conflict brings a tinge of philosophy to the work, and that’s what I think makes this game special.</p><h2 id="Footnotes">Footnotes</h2><hr class="footnotes-sep"><section class="footnotes"><ol class="footnotes-list"><li id="fn1" class="footnote-item"><p>Rong means soft and fluffy in Chinese, or mushrooms as in Japanese. <a href="#fnref1" class="footnote-backref">↩︎</a></p></li><li id="fn2" class="footnote-item"><p>The same applies to religions. It may sound heretic, but whether God exists is like a devil’s proof: the lack of evidence supporting it doesn’t lead to its non-existence. That means we can believe in God in some way. <a href="#fnref2" class="footnote-backref">↩︎</a></p></li></ol></section>]]></content>

        <content type="html"><![CDATA[<p>我站在一个小巷前。面前有两盏灯。</p><p>一盏，挂在左手边的墙上，灯是蓝色的。灯下面是一张破旧的办公桌，不知道是谁不用了丢在那里的。</p><p>另外一盏，稍微靠后，挂在右手边的墙上，鲜红色的。灯照亮了下面的一扇门。但奇妙的是，不像蓝色的灯那样，有灰尘在其中飞舞，红色的灯光中没有灰尘。光柱反倒像是什么实体一样，散发出象牙般的光泽。</p><p>我上前去试探红色的灯。我的手触摸到了坚硬的物体——好像这不是灯光，而是一块巨大的红宝石。</p><p>有点麻烦了，我想。我手上拿着这扇门的钥匙，可灯光却阻挡着我进去。</p><p>我回到外面，试图找到一点线索。当我眼睛瞟过那张破旧办公桌的桌角的时候，一抹白色引起了注意。</p><p>我凑上前去端详。是一副 3D 眼镜。不像现在常用的那种墨镜一样的 3D 眼镜。这是一块纸板，夹上红色和蓝色的透明塑料片做成的那种简陋的 3D 眼镜。</p><p>现在怎么还有这种东西，我心想。</p><p>我捡了起来，翻来覆去地查看。没有什么异常。但没有异常就是最大的异常，这东西不属于这里。</p><p>我看向两块塑料片，<em>红色和蓝色</em>。</p><p>搞不好是这样，我想。我带上了这副眼镜，除了世界变得单色以外，好像没有什么变化。不对。</p><p>起先发出光泽的红色灯光，现在失去了那份光泽。好像光泽转移了似的，蓝色的灯光开始带起光泽。</p><p>这个世界因为你所见而不同，我想起不知道谁说的一句话。</p><p>总之现在是可以通行了，我掏出钥匙，开锁进了屋子。</p><hr><p>进了屋子，一股腥臭味扑鼻而来。</p><p>拿了东西就走，不在这里呆着了，我告诉自己。</p><p>可这股腥臭味实在是令人难以忍受，于是我寻找窗户，给屋子换气。</p><p>我到了厨房，厨房的窗户紧锁，上面落满了灰尘，从里面看不见外面。这房子是几十年没住人了，我一边感慨，一边打开锁，推开窗户。</p><p>出现在眼里的是尸体。人的尸体。像垃圾一样堆在外面。垃圾桶里更是趴满了软体动物一样的死人，血顺着垃圾桶流下，汇聚到下水道。我感到一阵寒战，空气里腥臭味仿佛更浓了。</p><p>我立马把窗户重新关上，试图将刚才的景象赶出脑海。</p><p>我要找的东西是一个小盒子，首饰盒那样的。我很快就找到它了——它被放在靠里的卧室的床头柜上。我转头，想赶快离开这个鬼地方。</p><p>“我等你很久了。”背后突然有女声叫住了我。回头。女性坐在窗台上，黑暗中看不清她的脸。</p><p>外面打起了闪电，她的影子直伸到我脚下。</p>]]></content>

      <title>Let&#39;s Talk about Your Story -- Kimi no Hanashi, part 1</title>
      <link href="/posts/your-story/"/>
      <url>/posts/your-story/</url>
      
        <content type="html"><![CDATA[<h2 id="Forewords">Forewords</h2><p>I try limiting the words by just telling just a part of the book in this post. If there’s need, I would add more to it, but there’s no guarantee.</p><span id="more"></span><h2 id="What-is-it">What is it</h2><p><em>Your Story</em> is a novel written by Sugaru Miaki, published last July. If you read <em>Three Days of Happiness</em>, that is one of his first works as a online writer.</p><p>He mainly writes boy-meets-girl story – there are a lot of counterparts in MediaWorks Bunko<sup class="footnote-ref"><a href="#fn1" id="fnref1">[1]</a></sup>, where his previous works are published. If you’ve read <em>Kimi ga Tsukiyo ni Hikari Kagayaku</em>(lit. you shine in a night with moon) by Tetsuya Sano, the grand prize winner of Dengeki Novel Prize, it’s one of those stories with the same topic.</p><p>By the way, I feel a little better about <em>Kimitsuki</em> than Sano’s next novel <em>Kono Sekai ni “i” wo Komete</em>(lit. Fill this World with “i”). It’s not that the “i” pun makes it sound like a joke. It really means something, so I guess it’s OK. It’s just, the writer supplied with his own experiences: one of his acquaintance, a wanna-be writer, committed suicide. He probably tried to find the answer to a question, that for whom am I writing? And the worries is projected right onto the protagonist, who stopped writing upon his childhood friend, and his earnest reader’s death.</p><p>The main take here is that lightnovels from MediaWorks Bunko are different from the Dengeki ones – they are more literature and less lightnovel. In detail, they are easier to read than literature, with more aesthetic value than lightnovels. They dubbed it <em>light literature</em>, and it fits well.</p><p>Though it’s a different publisher this time, <em>Your Story</em> shares the same features with other novels with that label. So if you keep a little more attention when reading, rather than just treat it as another lightnovel, you will enjoy this book a little more.</p><h2 id="What-it-tells">What it tells</h2><p>As I said before, it is boy-meets-girl. But to be more precise, it is probably boy-misses-girl.</p><p>There are a young man and a woman having nothing. They meet each other. And then they lose each other. A little tragedy like this.</p><p>A writer had some talk about tragedies:</p><blockquote><p>Why makes a tragedy a tragedy? Because it is inevitable. And that lays the aesthetic foundation of tragedies. Why is Ancient Greek tragedies often related to fate? That’s because they – unlike us Easterners – had much trust in the personalities of human, and of deities – which are of humans in essence. So they in turn believed it is fate, rather than the evil in human personalities, that is the true, inevitable cause behind all tragedies. That’s what makes them loveable.</p></blockquote><p>I am not trying to argue about determining factors in Greek tragedies. But it helps us to categorize the reasons, and we can see both characteristic flaws, and fate take a part in it. She has a incurable and fatal disease, which is determined by nothing but fate. Both she and he have nothing in their past, but they have different attitudes towards it: she loves falsity, as it fills the blank in her heart; while he disgusts falsity, because it deprived him of his life. This decisive difference, makes them missing each other in the first part.</p><p>However, like in his previous books, Miaki sometimes likes to attribute one’s personality hugely to their background, family for instance. Like in <em>Koisuru Kiseichuu</em>(lit. parasites in love), the main charater grows mysophobia because of his mother. And the result is, it somehow brings a determinism tint to the story.</p><h2 id="A-Peek-into-it">A Peek into it</h2><p>The story starts itself with a poetic excerpt from <em>Cyrano de Bergerac</em>. But we can save it for now. Though the excerpt sheds light on the motif, or more probably, the motivation of the story, it itself doesn’t tell anything. One can proclaim, “caffe latte is great, and that’s it”, but that’s not why caffe latte tastes great. An explanation is meaningful only if there is something to explain.</p><hr><blockquote><p>I have a childhood friend who I’ve never met.</p></blockquote><p>So from the first sentence, we know that the story unfolds between “I” and the “childhood friend”, and the main twist is that I’ve never met this friend.</p><p>And this weird phenomenon is, as it turns out, due to the use of <em>mimories</em>, which is the word coined for artificial, false memories<sup class="footnote-ref"><a href="#fn2" id="fnref2">[2]</a></sup>. And no operations are needed to apply it, infusing some nanobots will do the job. So it’s as easy as having a cup of cocktail – go to the place, give an order, and drink it. The only difference would be how we call them – a bartender for one making cocktail, while a mimory engineer for one weaving mimories.</p><p>Chihiro Amagai suffers from parents since his childhood, who indulge themselves in mimories, and weasel reality at their best. As said in the following:</p><blockquote><p>When they need to take a trip, they would buy mimories of a trip instead. When they need to throw a party, they would buy mimories of a party instead. When they need to have a wedding ceremony, they would buy mimories of a wedding ceremony instead. By such kind of parents, I was brought up.</p></blockquote><p>That makes Chihiro’s childhood a rather miserable one. And as he dislikes his parents, he disgusts at the use of mimories.</p><p>He wants to forget this past of nothing, so he decided to erase his memories. However, by mistake, instead of forgetting his past full of nothing, he is filled with happy memories with Touka Natsunagi, a nonexistent childhood friend. And he inevitably falls in love with this girl, to the extent he actually sees her, and can’t help recalling mimories with her. He wishes that she is real so much, that he mistakes another one for her.</p><p>But another self in Chihiro denies all of this. “Isn’t it so pathetic, that the most beautiful memories I have are just another one’s made-up stories?” “Love is for those who do exist.” And she does not exist, it is just “a illusion of the summer”.</p><p>He is offered to choice to remove this fictional memory, which is easy as drinking the powder. But he hesitates to take the step. He tells himself, “it’s not the right place”, when he gets to the shrine to perform this ritual, he finds out that “I definitely can’t drink it in such bad weather”.</p><p>And the last strike comes. When he returns to his apartment from the shrine, he surprisedly find Touka, who doesn’t exist and shouldn’t exist, is opening the door next to him.</p><blockquote><p>The illusion of the summer still continues.</p></blockquote><h2 id="Footnotes">Footnotes</h2><hr class="footnotes-sep"><section class="footnotes"><ol class="footnotes-list"><li id="fn1" class="footnote-item"><p>Japanese publishers often use labels to categorize their books. For example, <em>Shogakukan</em> has labels like <em>Gagaga Bunko</em> and <em>Lululu Bunko</em> , the former is used for books targetting boys, and the latter for girls. <em>Dengeki Bunko</em> and <em>MediaWorks Bunko</em> are both labels of the publisher ASCII Media Works.<em>Bunko</em> only indicates the book is smaller in size(A6, to be exact), and there are labels without this suffix. <a href="#fnref1" class="footnote-backref">↩︎</a></p></li><li id="fn2" class="footnote-item"><p>From a translation of the novel. There is some kanji play in the word <em>gioku</em>. It has two kanji: <em>gi</em>, and <em>oku</em>. There are two kanji pronunced <em>gi</em> in Japanese, but have different meanings: one for “false, untrue”, and another for “artificial”. <em>Gioku</em> originally uses the former kanji, which is somewhat negative, so there is a movement to replace with the latter, which is more neutral. On the other hand, <em>oku</em> directly comes from <em>kioku</em>, which means memory in Japanese. <a href="#fnref2" class="footnote-backref">↩︎</a></p></li></ol></section>]]></content>

      <title>A Paper Plane to the Past</title>
      <link href="/posts/paperplane/"/>
      <url>/posts/paperplane/</url>
      
        <content type="html"><![CDATA[<h2 id="Epilog">Epilog</h2><p>Stephen Hawking said, although we could travel to the future, but going in the other direction was ruled out by Albert Einstein’s theories. But everybody knows that we cannot just stop thinking about it – the time paradox, the other self of that time, the butterfly effect. All we do is a little retreat from reality to virtuality, and in the fictional world, where the law of excluded middle doesn’t work, the impossible can become possible.</p><span id="more"></span><p>The past is also like a mirror. It reflects the current, and reveals the future. Though I’d like to babble more about reflection upon self, this is really not the place for such cliched preachment.</p><p>At least, the never ending fantasies about going to the past has spawned a ever increasing bunch of works about this topic. And this game is just one of them.</p><p>This game just suprisingly appeared in my Steam library<sup class="footnote-ref"><a href="#fn1" id="fnref1">[1]</a></sup>. I have heard of it years ago, but haven’t come to purchase and play it. So I decided to give it a try. And that’s the whole story.</p><h2 id="Part-2">Part 2</h2><p>Time travellers are, technically, travellers. Those works featuring trips usually have a great emphasis on encounters and parting ways. A light novel named <em>The Journey of a Witch</em> might well fall into this kind. I haven’t read it, so I’m not sure. What I’m certain about, is that <em>Spice and Wolf</em> doesn’t care much about it. Maybe it’s because Lawrence always faces unfriendly people. <em>Girls’ Last Tour</em> is similar, although it is a bit more about sightseeing.</p><p>In a journey, one runs into all kinds of people, and usually, they never cross their paths again. So we learn how to say goodbye.</p><p>And the same, somehow, applies to the time travellers as well. Usually after departing from a spacetime, a world line, one cannot comes back. And unlike the negotiable spatial distance, the temporal one is absolute.</p><p><em>Back to the Mother</em> features similar plots. Despite its frivolous atmosphere, bold fanservices, and the title, the manga tries to tell a serious story. Yuu, the protagonist, is such a fan of his mother, an once idol band member, that is near the extent of Oedipus complex. But one day, the mom’s glorious figure mysterically turns into a graceless unsliced nigiri(sushi, maki, whatever) with an face only appearing in comedy mangas. Along with this eerie transformation, he often find himself transported to the past, when his mother was of his age.</p><p>Each time he was sent to the past, Yuu gets to know, a little about his mother’s youth. And at the same time, he and Hanada get closer to each other, his teacher but once a friend of his mother’s. While he manages to fix his mom’s past the way he knows, Hanada is becoming more and more important to him. Finally, he uncovers the reason why his mother turns into a sushi roll, and prevents it.</p><p>Knowing Yuu will be sent back to his time and unable to come back, Hanada calls him out to a park, to say farewell to him, and to this forever unrequitted love.</p><p>The manga was appeared to be, somehow, hastily concluded. But the up side of it is, it saved the work from lengthy, remotely related stuff, like new characters, stories about the new characters, new places and fanservices, which is common for many serial works. It is usually good, or, OK, for those slow-paced works, for example, <em>Boarding School Juliet</em> or <em>Nisekoi</em>(maybe more prevalent in lightnovels), but it really hurts the compact story line, which is one of the centers of this manga, the other one is, of course, the tragic female main character Hanada.</p><h2 id="Part-1">Part 1</h2><p><em>The Season of 12 Colors</em> tells a story like <em>My Tomorrow, Your Yesterday</em>(shortened to <em>Bokuasu</em>).</p><p>And I think it somehow well conclude the main plot of this story. So if you have read the novel, or watched the film, you are already spoiled. Sorry.</p><p>Made by <em>Class Tangerine</em> which is also the developer of <em>Gaokao Love 100 Days</em>, this one is kind of short and concise, and the game ends within an hour.</p><p>I think the same plot usually means the same climax. And what can I say?</p><p>The largest difference between separation and death is that: after separation, you know they are there, but after death, you know they aren’t anywhere. Another short VN by the same group plays on this difference. If you have only 12 hours to live, what will you do? Be moody, give a grave talk, watch your friends and families cry? The protagonist is in the same situation, but things are somewhat different: everyone treats him as if he were just going to another place rather than dying, and that is no serious matter. So even if the protagonist proclaims, “I am going to die! Please treat me better!”, others just see it as a joke. This twist makes the plot which is going to be sad, a hilarious one. And in his last minutes, even the protagonist himself stopped worrying about his death, but starts to think about saying something cool as his last words. And he ridiculously fails.</p><p>It is included in the game <em>Short Stories Collection of Class Tangerine</em>, along with another 9 stories. And they are all interesting stories.</p><p>And Greek tragedies often have this topic, that one struggles to rewrite their doomed fate, but ended up realizing that it is unchangeable. In the end, they wrap up themselve, to paint the final stroke on the canvas of tragedy.</p><p>Unlike in <em>Bokuasu</em>, the time does not flow backwards for Mo Li(jasmine in Chinese), the heroine, since the beginning, and not until her mother’s death. It gives rise to a turning point, which marks the end for the protagonist.<sup class="footnote-ref"><a href="#fn2" id="fnref2">[2]</a></sup></p><blockquote><p>This is the first time for Mo Li to meet me, and the last time I see her.</p></blockquote><p>MC ends up telling fairy tales to the then 6-year-old Mo Li, play with her, and teach her how to fly a paper plane. And in the last, he has to say goodbye to her, knowing he will never see her again.</p><blockquote><p>We will come across again, and a lot, in the future.<br>So do remember, the signal is the paper plane.<br>Because if you write a letter on it, it will reach the person on your mind.</p></blockquote><h2 id="Prolog">Prolog</h2><p>I found out the post is a little too long for a short VN like this, but it’s too late.</p><p>So I’ll just leave it like this.</p><h2 id="Footnotes">Footnotes</h2><hr class="footnotes-sep"><section class="footnotes"><ol class="footnotes-list"><li id="fn1" class="footnote-item"><p>It turns out that NVLMaker, the publisher of <em>Tiny Snow</em>, gifted the game as a part of the package. Thank you NVLMaker. <a href="#fnref1" class="footnote-backref">↩︎</a></p></li><li id="fn2" class="footnote-item"><p>I’m translating by myself, since I played in Chinese. The game is available in English as well, so don’t fret. <a href="#fnref2" class="footnote-backref">↩︎</a></p></li></ol></section>]]></content>

        <content type="html"><![CDATA[<p>有人提醒我 SSL 证书过期，于是我想起来，我还有一个博客。</p><p>或许是因为 <a href="http://acme.sh">acme.sh</a> 更新，或是什么变化，总之就是挂了，十分遗憾。但挂在 GitHub pages 上的<a href="https://noirgif.github.io">主页</a>大多数情况下都不会挂，所以可以去那里看一看。</p><span id="more"></span><h2 id="回不来的时间">回不来的时间</h2><p>新年的冬风，今年也是格外的刺骨。虽然没有新闻里芝加哥那么冷，但至少晚间在回去的路上，不穿上厚外衣，戴上手套，捂紧帽子，是免不了要瑟瑟发抖一番的。</p><p>农夫冻得手脚冰凉，在与蛇的战斗中，两手僵硬，有劲无处使，落得一个被蛇咬的下场。</p><p>元月27日或许是一切混乱的起点。</p><p>这一天，弄到了一个卖手机亏损的公司生产的家用主机。于是 Jirga Para Lhao 被拯救了。但 30 个小时就这样过去了。</p><h2 id="青鸟不会做杀人的梦">青鸟不会做杀人的梦</h2><p>我有时候会思考应该如何写一篇感想。</p><p>客观性是我试图避免的：我想写一些主观的、个人的感受，而不是所有人都会感受到、都可以表达出来的东西。我想写的是我个人的感想，而不是所有人的感想。之前的尝试在这一方面都不算是令人满意——大多时刻只是事实的罗列，或者是单纯的侃侃而谈。</p><p>聊天倒是也不坏。蔡康永的情商书（为什么我会看这么大众的书，不过转念一想，倒也有种别样的趣味）里就有“分身”这一说法。人每时每刻都需要和他人交流，但往往会忽视与自己的交流。与自己的交流听起来好像很奇怪。尝试培养另外一个不同的自己，跟这个自己对话。这可以说是一种审视自己的方式，也可以是一种批判性思考的方式。从这一个方向用尽九牛二虎之力也推不开的门，说不定换个方向就能轻松打开。</p><p>回到侃侃而谈。可能变成侃侃而谈也能从侧面说明，想从心灵这个湖里，捞出感想的鱼，不是件容易的事情，把捞上来的鱼卖给他人，也不是件容易的事情。不过鱼还没有捞上来，就想着销路，算是有点眼高手低了。</p><p>不过鱼有大的鱼和小的鱼，就像苹果有甜的苹果和不甜的苹果。大的鱼属于那种容易发现的。比如看完《活着》，感受到悲伤、无奈、沉重。不过转念一想，悲伤和喜悦都只是游在表面上的鱼，而在深水里的，是那种达观、顽强、活下去的力量，是这股力量支撑着人走下去。活着才有酸甜苦辣，活着才有风雨彩虹。</p><p>结果又变成万人都能说出的感想了。我大概不适合这差事。</p><h2 id="同学聚会">同学聚会</h2><p>参加了高中的同学聚会。令我惊奇的是，我没那么快活。</p><p>用一句大俗话来说，就是感觉少了点什么。</p><p>我曾经不止一次梦到过和高中同学搞事——建车站、开组会，无所不为。这或许这是我高中过于安分的反作用。搞事的时候我是快乐的，虽然在梦里的事都说不清楚，但大概的确是这样。</p><p>所以一个很大的可能就是，因为没怎么搞事。</p><p>灰姑娘是不是因为穿上了水晶鞋，所以不能自由奔跑了呢？</p><p>我翻遍了卡拉 OK 的歌单，翻遍了火锅的锅底，但都没有找到答案。</p><h2 id="冬天来了，冬天还会远吗">冬天来了，冬天还会远吗</h2><p>在严寒中，在风雪里，食堂一个接着一个地关门了。有的等春暖花开之际会像燕子一般归来，有的则永远也不会回来了。</p><p>可我仍然没有吃到藤椒口味的浇汁饭。</p>]]></content>

        <content type="html"><![CDATA[<p>今天没打游戏。</p><h2 id="小说">小说</h2><p>磨了一点 Your <del>Diary</del> 的感想，就没动了，买了另外一本三秋的书，加上一本书凑免邮。反而是看纸城境介的<em>继母的拖油瓶是前女友</em>看到快 6 点。</p><p>很有趣的小说。男性向的。</p><p>因为看轻小说不用带脑子，所以这也是不带脑子的评论。这也是我的一种心理安慰。一个人如果因为一本无趣的小说而熬夜，那未免也太空虚了吧。</p><p>在访谈中，关于连载，作者纸城大致是这么说的：如果小说被印刷成书出版，那只能让读者享受 3 小时；而如果放在网络上连载，则能够让读者每周都享受 168 小时。</p><p>关于这部书有趣的地方，作者大致是这么说的：我写这部作品，就专注于这一点，而不是加入学园祭等各种元素来充实内容，这使得这部作品非常纯粹。</p><p>因为我记的不太清楚了，所以就不加 quote 了。当然这也不代表我个人观点，虽然说人会把记忆改造成自己想要的样子，但我觉得这观点怎样都好，所以就忘的差不多了，更别说根据自己的好恶改造了。</p><p>我个人觉得误会是这部作品的一个支撑，也是全篇反复出现的一个要素。男女主人公因为小小的误会，关系出现了隔阂，导致最终的分手。男主自认为讨厌女主，但心里还给女主留着位置，他并努力和女主保持着适当的距离；而反观女主，男主在面前的时候针锋相对，不在面前的时候变身大花痴。导致怎么看，都是变相秀恩爱。</p><p>这让我想起了作品时间和现实时间同步的一部网络小说，其天气也是忠实于日本某地的天气。可名字忘了。</p><p>今天下雨。</p><p>看了一点人间失格，感觉不能理解。先不管三张相片是想表达什么（从内容上看推测是概括了主角的一生），几页看下来，大致是一位神经性厌食症少年的独白。具体是不是还要继续往下看。</p><h2 id="摄影">摄影</h2><p>我不摄影。</p><p>看了一篇关于 Magnum Contact Sheets 的博客，讲的很长很详细，地址忘了。</p><p>Contact sheets 是在底片时代，摄影师为了降低成本，就先把底片的缩小版印下来，再在其中挑选想要的照片。从 contact sheets 中可以看到摄影师的思考，过程，以及失败。Magnum 是有名的摄影师社区，其成员都是经过遴选的，因此这本书里的 contact sheets 也可算是大师级别的作品。</p><p>看到 Dali Atomicus 的时候，我以为里面的人是随便一个演员，结果一查是达利本人，而其创意也来自达利的画 <em>Leda Atomica</em>，里面的物体都是漂浮着的，在照片中该画被悬在右侧。照片里的猫也是真的，是助手丢出去的。大概那时候没有动物保护组织，可以随便来。照片一共拍了28次，可以说不管是摄影师，达利，打扫的人，还是猫都辛苦了，猫还会被水浇到，所以可能最辛苦。</p><p>总而言之，文章想对广大摄影爱好者表达的几点建议，一个是多拍，一个是拍了要看，一个是以前拍的也要看，说不定会有新的发现（因此不要立即删掉觉得不好的照片）。</p><h2 id="字体">字体</h2><p>方正面向移动端阅读，推出了方正悠宋。当然要钱，而且不能发布。因此我没用。当然如果遇到什么好的免费的衬线体，大概是会换的，不然英文是衬线，中文是黑体，不免有些不协调。</p><p>注：移动端是这样，电脑端可能不是这样。</p><p>Hymmnos 字体也会加回来的，大概。</p><p>其他的记不清了。</p><p>想不到要写什么了。</p>]]></content>

      <title>Kagami no Kuni no Iris -- An Unsurprising Non-surprise</title>
      <link href="/posts/kagami-no-kuni-no-iris/"/>
      <url>/posts/kagami-no-kuni-no-iris/</url>
      
        <content type="html"><![CDATA[<p>Headnotes:</p><ol><li><em>Kagami no Kuni no Iris</em>(literally Iris in the world of mirror), is a parody of Lewis Carroll’s <em>Through the Looking-Glass</em>, which is translated to <em>Kagami no Kuni no Alice</em> in Japanese.</li><li>Iris refers to SCP-105, who once had the name of Iris Thompson.</li></ol><hr><p>When I see the poster, I was like, OMG Akira is writing something about SCP! Shit I’m gonna buy it! Wait, it’s only 330+ pages and costs 1200 yen! That’s twice the price of an ordinary lightnovel!</p><p>The price makes me hesitate for a while, but I bought it anyway.</p><p>I think it is inevitable to showcase SCPs’ effects when introducing them. We are reading a story, not just a piece of description. We expect to see SCPs in action, not in tales or behind hardened glass. So the choices are limited: we need them to breach, to break free, in order to unleash their full power. Keeping them in containment wouldn’t provide us much opportunity to diverge from the original description text and go further in terms of creation and originality. And that’s what their poster suggests, <strong>A large scale containment breach</strong>.</p><div class="figure " style="width:;"><a class="fancybox" href="https://res.cloudinary.com/noirgif/image/upload/v1540390376/nir.moe/kagami-no-kuni-no-iris/iris_poster.jpg" title="The poster from Bookstore Hifumi, before its release being delayed to Sept. 4th" data-caption="The poster from Bookstore Hifumi, before its release being delayed to Sept. 4th" data-fancybox="Iris"><img class="fig-img" src="https://res.cloudinary.com/noirgif/image/upload/v1540390376/nir.moe/kagami-no-kuni-no-iris/iris_poster.jpg" alt="The poster from Bookstore Hifumi, before its release being delayed to Sept. 4th"></a><span class="caption">The poster from Bookstore Hifumi, before its release being delayed to Sept. 4th</span></div><p>Moreover, something deep in me is curious and excited to see a brand new breath blown into the somewhat gloomy and serious SCP objects. Akira is well known for writing abnormal things: he wrote for Yumenikki, and also that ECHO<sup>1</sup> song by GUMI/Megpoid. Therefore, it is completely sensical for him to put his hands on the SCPs, which is also a symbol of abnormality.</p><p>Admittedly it is a hard take: you may end up with an amalgamate which lets everybody down and pisses off readers from both side. But it’s Akira we’re talking about, maybe he can make it. At least that’s what I thought when I saw him on the cover.</p><p>And here’s Shidu, who has made PVs for almost all Kagerou Project songs(some others done by the hands of Wannyanpuu), then the illustrations for the KagePro lightnovel. I just mention him by the way, though I cannot think of someone better than him to handle illustrations for cool things like the SCP.</p><p>That’s what I thought before reading it, and after reading, I would say: that’s what one would expect out of Akira.</p><p>The one and only good thing is that it is good for an introduction to the SCPs. In the novel, the specialties and backstories of the SCPs are carefully covered. Like how Iris discovered her ability, and the tragedy MTF Rho-71 “Origami Toads” encounters during their exploration of the carnival of horrors(SCP-823). And it even goes to length about what an SCP is, and what the Foundation is for. So almost everybody could enjoy this novel without looking up everything and wonder what on earth they are talking about.</p><p>Maybe it is also the reason for why almost all SCPs involved lie in the range of 000 ~ 999: they enjoy more popularity. However, it’s just a possibility.</p><p>But one thing a reader might notice is that there are some changes to the original SCP stories. For example, in the SCP-823 expedition, Akira saved one of the Rho-71 soldiers from forced sexual entry into the eye. Instead, he killed the poor soldier with a SCP-173 style neck-snapping by the hippo mascot, and then blow up the displaced head as if it is a balloon. It’s OK, since usually the mascots are the ones that hand out balloons to visitors. I guess Akira had to do it because “forced sexual entry into the left eye” may be too much for a casual lightnovel reader, let alone for himself to depict such a scene.</p><p>Something making me feeling unsatisfied is that we are dealing with safe objects most of the time. Except for the Teddy bear, the carnival of horrors, and Dr. Bright’s pendant, almost everything that plays a part in the story is safe. Some other unsafe objects, like the old man, the young girl, and the sculpture, are only mentioned orally.</p><p>The thing that confuses me the most is that almost everybody does not treat the main character as a D-class personnel, even though he’s wearing that orange jacket all the time. For example, he’s allowed to operate the coffee machine, which needs security clearance 2 to do so. And he’s not terminated on sight by those MTF soldiers when in the amusement park: they should kill any straying D-class personnel, but in the end they leave him alive. So effectively the main character is just cosplaying a D-class personnel, nobody takes it for real.</p><p>And the most distressing part, there is no large scale containment breach as the poster boasted, which is a huge let down for me. Probably we can witness one in the sequel(it’s Kagami no Kuni no Iris <strong>1</strong>, so there will probably be a 2, if the sale goes well of course). But first thing first, Akira needs to set up the stage, and Book 1 might serve such a purpose.</p><p>However, the book ends in a way that even if Akira won’t write a book 2, it will be still alright. To be exact, the protagonist, ███, is found a visitor from a parallel universe. His ability, with Iris’ help, makes this inter-world travel possible. In the epilogue &quot;Milestone Iris, he’s sent back to world he belongs to, so the whole story is wrapped up where it begins.</p><p>It’s, well, not that bad. Everyone’s doing it. Even though I like the way of leaving a cliffhanger and keeping everybody in suspense, like what Falcom did with the Cold Steel, the reality is hard: one don’t know when he stops until he stops. There are many obstacles to the sequel: the sales, the reception, and the worse among them, the writer himself. And if one keeps the expectation too high and fails to answer it, it will be a hard landing. Although Akira’s nowhere near Hikari Sugii and Hitoma Iruma, he is still eligible for one of the guys who are the best to start a story, but the worst to conclude it. He’s not working on series(including the cases where he tried but failed) since the end of Sasami, which is Nov. 2013. So it might be hard for him to maintain the momentum and continue the adventure. So such an end may indicate his lack of confidence, or simply his lack of ideas for the second volume.</p><p>So the best we can do is to be patient and hopeful, to wait for the sequel of the story. I can give no final judgment until the final piece is in place.</p><h2 id="Footnotes">Footnotes</h2><ol><li>It has millions of views on Niconico and Youtube but I don’t know what the hell’s going on. Can someone tell me please?</li></ol>]]></content>

        <content type="html"><![CDATA[<p>The title comes from <em>Sunless Sea</em>, an adventure game where the player explore the dark sea of unknown. However, it has nothing to do with that game.</p><div class="alert warning"><p>The translation of Japaneses words are done with best effort, in another word, there is no any kind of guarantee that the translation is official or consistent with the official one.</p></div><div class="alert warning"><p>This article contains spoilers, which may harm or even completely ruin your experiences, here’s a non-exhaustive list:<em>Hikari no Umi no Apeiria(Apeiria of the Sea of Landscape)</em><em>Steins;Gate</em><em>Eiyuu Densetsu Sen no Kiseki(Legend of Heroes: Trails of Cold Steel)</em><em>Planetarian ~ Chiisana Hoshi no Yume</em><em>Newton to Ringo no Ki(Newton and the Apple Tree)</em><em>Eden</em> *(spoiler: it is not spoiled)</p><p>Progress with heed.</p></div><h2 id="Preface">Preface</h2><p>This post does not contain what you’d expect from a typical game review – the overall plot, the execution, the voice casts and so on, because it is kinda lame to write something that is already on the Internet, especially for a year-old game like Apeiria(although I myself is the reason why this post is delayed for half a year).</p><p>So instead, the post focuses on elements and ideas, either central or peripheral to the game, and expands these concepts further. This strategy makes the post a little out of focus, and here’s another reason for it: the game is in a sense mediocre, because it does not exceeds one’s expectation.</p><p>I don’t mean the game is bad. On the contrary, <em>Apeiria</em> is a good combination of popular concepts and has a capturing story. After all, if the game is really not good enough, I wouldn’t even bother to post an article about it, let alone go through iterations in this six months. The point is, however great the game is, <em>Apeiria</em> is just a galgame, nothing more, nothing less.</p><p>It is hard to define what makes an art piece unique, but for a game, drawing moustache on character’s face and claiming the originality would be unique for the blatant copyright infringement. For a game, it could have great arts and music, humanly characters, a catching plot, or a thought-provoking theme. Kikiyama’s free game <em>Yume Nikki(Dream Diary)</em>, for example, features exploring exotic scenes with an unrealistic art style, whereas <em>The Last of Us</em>, an action game by Naughty Dogs, portrays humanity in a postapocalyptic world. And that’s one of the reasons why they receive acclaims from the fans.</p><p>That being said, people’s mileages can greatly vary, and there’s no universal standard for good or bad games. So this post is not about judging whether a game is good or not, but just a peek into the core of the game.</p><h2 id="No-Sense-Online">No Sense Online</h2><blockquote><p>Note: it comes from <em>Only Sense Online</em>, an online lightnovel by Aroha Zachou(literally Chairman Aloha) later published in print. AFAIK this lightnovel does not feature OreTueee.</p></blockquote><p>The story of <em>Apeiria</em> happens in 2035, and people profit from the highly developed VR technology and AI research. Reiichi Kirishima, works together with his friends to build the VRMMORPG <em>Second</em>. The second is a fantasy world of sword and magic. One may suspect fantasy makes up most of the game, just as Reki Kawahara’s lightnovel <em>Sword Art Online</em>, and most online novels do. However, the story puts emphasis on both the real world and the virtual one. But the best part is, the two seemingly contradicting themes are tactfully merged in the end of the game.</p><p>Back to the fantasy world. Usually to make a party, we need members of these sorts:</p><ol><li>Short- and/or mid-range attackers. They are usually deployed to defend the party members behind. Examples are thieves, swordsmans, lancers, and fighters. There should better be a tank to take the damage.</li><li>Long-range attackers or scouts. They can discover enemies early, leaving enough time for preparation. Their attacks won’t be countered by short-range enemies. Archers, for example, belong to this category.</li><li>Mages. If physical attack and magical attack are largely different in ways of effects and costs, then mages are needed to ensure a more comprehensive scope of attack.</li><li>Healers or supporters. Their importance is never overemphasized.</li></ol><p>Take Falcom’s <em>Legend of Heroes: Trails of the Cold Steel I</em> as a motivating example, we have:</p><ol><li>Short-/mid-range: Rean(tachi), Laura(double-handed sword), Fie(dagger/gun), Jusis(knight sword), Gaius(spear)</li><li>Long-range: Alisa(bow), Machias(shotgun), Eliot(staff), Emma(staff)</li><li>Mages: Emma, Eliot</li><li>Healer: Eliot, Emma</li></ol><p>In this game everyone is able to use arts(what magic is called in this game), therefore the main difference between mages and others is that mages have higher magic attack/defence stats. So Eliot and Emma are not required as mages(though they are required as healers).</p><p>Trails of the Cold Steel allows only four characters in the battle, with two substitute members, there are at most 6 members in the party most of the time. Let’s see how Falcom arranges the party in each chapter to make sure it is balanced:</p><ol><li>Rean(S), Alisa(L), Eliot(H), Laura(S)</li><li>Rean(S), Emma(H), Fie(S), Machias(L), Jusis(S)</li><li>Rean(S), Gaius(S), Jusis(S), Alisa(L), Emma(H)</li><li>Rean(S), Laura(S), Fie(S), Machias(L), Eliot(H)</li><li>Rean(S), Laura(S), Jusis(S), Emma(H), Millium(S)</li><li>Rean(S), Alisa(L), Eliot(S), Machias(L), Fie(S), Crow(S)</li></ol><p>Though there’s another system restricting the selection of members: there are four types of normal attack damage: slash, pierce, thrust, strike. Normal attacks from different characters have varied affinities to these types. For instance, Rean’s tachi attack has a high slash affinity, while Laura’s affinity to both slash and strike is high. And different enemies can be easily unbalanced by different types of attack damages. So the damage throughput could be increased by  using the right person to attack the enemies, leading to more unbalancing and link attacks. Though the system is marginal since the bosses can hardly be unbalanced(they don’t have this kind of weak point), the affinities of the characters are carefully arranged to make sure all four types are covered in the above party setups.</p><p>However, in Apeiria, we see an unprecedented bias of party member roles. The constitution of the party is like this:</p><ol><li>Reiichi: short/mid-range attacker, main damage output, can revive himself and buff teammates</li><li>Miu: sniper and healer. So roughly speaking, she’s Ana from <em>Overwatch</em>, while being a tsundere younger sister.</li><li>Kuon: swordswoman, tank(she have a spell to call out an inpenetrable shield)</li><li>Mashiro: thief, able to exchange money for rare items</li><li>Apeiria: mage, persumably a DPS(second to Reiichi), unavailable most of the times.</li></ol><p>As we can see Reiichi is ridiculously overpowered – he himself is a whole team. I guess it is probably due to the story. If my memory serves me right, the party is like the following in different times:</p><ol><li>Reiichi, Miu, Kuon, Mashiro, Apeiria</li><li>Reiichi, Miu</li><li>Reiichi, Kuon</li><li>Reiichi, Mashiro</li><li>Reiichi, Miu, Kuon, Mashiro</li></ol><p>Nanami and whatever are taking up much less a role, so they aren’t counted. Discussion about them can be left to the post about the game’s spinoff <em>Casablanca no Kishi(Knights of Casablanca)</em>, if there is one.</p><p>Given this plot requirement, the usual party makeup does not make any sense, because Reiichi will have no chance of survival, turning the <em>Second</em> into souls-like games, and <em>Apeiria</em> into <em>Re:zero</em>. Powering up the heroines could be a good idea, but that will render the last fight, a one-on-one fight with the last boss unimpressive.</p><p>This kind of unbalanced protagonist is mushrooming in lightnovels these years. With the uprise of coarse grained net novels, the use of such template is hitting new high. Let’s yell out some of the catch phrases:</p><p><em>Shuujinkou saikyou</em>(protagonist the mightiest)!</p><p><em>Ore tueeee</em>(I’m so stroooong)!</p><p>Such settings bring about some benefits. One of them is that the story can always be kept under control. There’s no need for ex machina, because the overpowered protagonist themself is the ex machina. Another is that a group of readers are usually happy about it. Admittedly I was one of them.</p><h2 id="Apeiria-of-Love-and-Desire">Apeiria of Love and Desire</h2><blockquote><p>Note: it comes from <em>Aiyoku no Eustia</em>. <em>Ai</em> means tarnish rather than love, while <em>yoku</em> means wings instead of desire.</p></blockquote><p>In August’s visual novel <em>Aiyoku no Eustia</em>, we have multiple routes, from Ellis the pharmacist to Eustia, the main heroine in the story. Unlike other galgames, in <em>Eustia</em>, the common route does not branch to personal routes at the same time. It first has a branch off to Ellis’ route, then Fione’s, on and on, and in the end Eustia’s. Such a structure allows huge savings, since one thing in one route needn’t be reintroduced in another. Moreover, it makes all routes sequentially related, so the player can regard the story as a well-structured whole, rather than 5 separate ones.</p><p>Another visual novel created by Laplacian, <em>Newton and the Apple Tree</em>, has the same flow of story. However, the game forces the player to go into Ravi’s route once before progressing to the Japanese, the maid, and Alice.</p><p>However, it is not as simple as spreading out to personal routes sequentially. There should be key events to set the backgrounds of the personal routes apart. In Nitroplus’ adventure (text) game <em>Steins;Gate</em>, the D-mail is the key. If Rintarou sends the D-mail to Firis, the whole landscape of Akihabara will not be the heaven of otakus, but still a street of electronics. Therefore, the common route before and after this branch into Ferris’ route differs significantly.</p><p><em>Apeiria</em> is also a galgame that has such a structure. However, it integrates all routes into one. As a side-effect, choices are eliminated, and we have a truly linear storyline. But here comes the problem: how can we avoid conflicts of different routes? Even we can manipulate the protagonist’s feelings for the heroines, we cannot simply take things in the previous route as unhappened.</p><p>To resolve the conflict, Silky’s Plus Dolce resorts to the good old time leap: if we can revert to the time before the personal route begins, then everything works perfectly. Therefore, in the end of routes the protag leaps to one year before the current time, losing almost all his memories, including the ones with the heroine.</p><p>However, there is no elixir, and the seemingly powerful time traveling has its side-effects, that is the time paradox. In <em>Steins;Gate</em>, to avoid the time paradox being happening, Rintarou has to stab Kurisu while avoiding bumping into his past self, when he goes back in time to save Kurisu. Sorry, but my poor wording makes it sounds a little silly.</p><p><em>Apeiria</em> goes further than that: rather than not touching the paradox, it provides a new theory to get over it. The theory states it is not the case what one does now has no impact on the past. When we travel to the past, the future is not undone: it affects now so that everythin will converge to what has happened in the future.</p><p>Like this one, there are many theories presented in <em>Apeiria</em> about time, causality and so on. Just like the <em>Koujin Nanase</em> part of manga <em>Kyokou Suiri(In/Spectre)</em>, although every theory, in itself, is unsound, it has its reasonable parts. And in the showdown, all rational parts are combined to make the final, sound theory.</p><h2 id="Mechanic-Princess-in-the-Dying-World">Mechanic Princess in the Dying World</h2><blockquote><p>Note: it comes from the light novel <em>Kakeyuku Toshi no Kikai Tsukihime</em>, wherein a robot girl meets her end.</p></blockquote><p>Everyone knows an awful lot about the greatness of AI, but much less about its correct use. Fortunately, we have Silky’s Plus Dolce to point out the right way: to make one’s own girlfriends.</p><p>It is a reiterated theme - there are already works about having android girls or something like that as protagonists or heroines. In manga <em>Mahoromatic</em>, the main heroine Mahoro is a female android, previously soldier, who comes to Misato’s house after knowing she has only a year left. Visual Arts Key’s visual novel <em>Planetarian: The Reverie of a Little Planet</em> features Yumemi Hoshino, a female robot narrator in a discarded planetarium. In the anime series <em>Plastic Memories</em>, we have android Isla(Aira) working with Tsukasa, the protagonist, to retrieve androids that are near the end of their life.</p><p>It seems not really good – they nurtured a stereotype about androids and robots – they are powerful but vunerable, they have short lifespan, they have difficulties understand human emotions, so on and so forth.</p><p>And the real bad thing is that Apeiria, one of the main heroine, and the center of the whole story, does not at all fall out of these stereotypes.</p><ul><li>Power: she hacks tens of billions of computers around the world to make her Apeiria Network.</li><li>Vulnerability: she has not once successfully repelled Thinker’s virus attack. And when the Apeiria Network is hacked, she cannot disconnect herself from the network to avoid being disabled.</li><li>Short lifespan: near her own route, she has only one year to live(it’s Mahoro!)</li></ul><h2 id="Exception">Exception</h2><blockquote><p>Note: it comes from the movie <em>Inception</em>, maybe.</p></blockquote><p>Tired and bored after a day’s work, we may want to escape the real world, and embrace a virtual one. So one may imagine a switch mechanism for it: switch on, and we’re in the realm of imagination, and off, back to the real world.</p><p>But such a kind of mechanism overlooks the interplay of this two worlds. Usually one playing a game is aware of its virtual nature, and is not separated from the outside. Take <em>Ready Player One</em> for example, control of the character in game is also affected by the lost of balance in the real world. So the virtual world can be greatly influenced by the real world, but it is often not the same the way around.</p><p>With this asymmetry taken into consideration, a layered structure seems better to express this kind of relationship. Here we adopt the idea of a stack. The virtual domain is on the top, while the reality is in the bottom. The virtual world dominates our feelings when present, but we fall back to earth upon exiting the imaginary.</p><p>So the reality-virtuality dichotomy can be expressed by a stack of size 2, let’s call it world stack from now. The real world is the first element of the world stack, and also the only element if we’re in reality. But if we dive into the virtual world, like OASIS, then we push the game onto the stack, and there’s two elements: the virtual world on top of the real world.</p><p>And it is easy to extend the world stack to allow more than 2 elements.</p><p>In a chapter of Douglas Hofstadter’s book <em>Gödel, Escher, Bach: an Eternal Golden Braid</em>, Achilles and the tortoise travels in and out Escher’s works by drinking blue and red phials. The travelling is done in a similar manner: going deeper into prints is like the push an item onto the stack, while going out out of the piece of artwork is like popping elements of the stack. And the world we are directly feeling is the top element of the stack.</p><p>Though it bears resemblance to the stack data structure, the world stack has a definitive difference: we do not know how many elements are in the stack at any time. So here’s the problem: how can we know if the top element of the world stack is the real world? In other words, how can we tell if the world we’re right in real or not?</p><p>We can check this by popping out elements, if there’s nothing to pop, then the world stack is empty, and the last world we popped is the real one. But note that popping out real world usually means one’s death. One never knows if the red pill is authentic before he washes it down. So we do not know if the current world we’re living is real, the only thing we know is since the real world is at the bottom, if we find out the current world is virtual, we can always pop out of it without getting ourselves killed.</p><p>But the safety to pop out does not mean it is doable. For example, it is claimed that people in heaven never dies. So people are not able to access the world beyond heaven, just like the girls cannot come out of the screen.</p><p>To solve this problem, <em>Apeiria</em> introduces a world structure similar to the stack model, but is different in its essence. In the game, the top and the bottom of the stack are connected, therefore the way in becomes the way out.</p><h2 id="Verdict">Verdict</h2><p><em>Apeiria</em> is a interesting combination of popular topics – AI, virtual reality – on the good old basis of Sci-Fi and fantasy. Unlike in <em>Sword Art Online</em>, where one is constant aware the world’s nature, <em>Apeiria</em> weaves a story across the borderline of reality and fantasy, which makes it capturing and different.</p>]]></content>

        <content type="html"><![CDATA[<p>It was unreal, but it felt real.</p><p>We are facing a giant dragon – given that all dragons are large – to fight our ways up the tower.</p><p>The tower of Yggdrasil is still looking down upon the world from the center today.  Modeled after the boundary tower in Amakusa, Tokyo, which is the birthplace of a phenomenal VRMMO game, Yggdrasil is a lofty tower, too.</p><p><em>Like a needle piercing into the space.</em></p><p>A crystal one, though, to fit in the overall fantasy art style of the Second. And like the boundary tower, Yggdrasil boasts a whole lot of floors – 1000 of them, to be exact – crammed with all kinds of monsters and challenges.</p><p>And we are the first one to set our feet on the tenth floor. It is almost cliche to put some strong monster in the floors of ten’s multiples, and the AI is clearly sticking to this common practice when creating the Second.</p><p>One dragon was already beat when we first enter this tower, that is, the mother dragon. It was quite a tough one: it even nearly managed to suffocate us by burning out all the oxygen with its breath. But now, after countless battles, our team is invincible, and the dragon doesn’t stand a chance.</p><p>Whoosh! its sweeps the ground with its left claw, but in vain. It took too much damage to maintain its swift actions. Time to deliver the last strike. I called out to my little sister.</p><p>“Miu! Covering fire!” “Gotcha!”</p><p>The dragon roared in pain as the bullet penetrates the dragon’s eyes. The monster raises its head, it want to cast a breath.</p><p>“Kuon!” “Needless to say!”</p><p>Kuon cast the spell, which forms a shield protected all of us from the devastating breath. I looked to Apeiria, and she knows what I’m gonna do in an glimpse.</p><p>“You are powered up, owner, get in there!”</p><p>I run forward towards to dragon, to deliver the final blow.</p><p>“Mashiro, come back!” “Roger!” The little silouette who’s attacking with combos jumps back, agile like a humming bird.</p><p>A few steps forth, I get face to face with the hideous monster. Time for my ultimate sword.</p><p>“1/8!”</p><p>Eight beams spreads out in an instant, all of them punching the dragon, lighting the last moment of this floor master.</p><p>With a death agony, the large figure collapsed to the ground and dispersed.</p><p>After I confirmed the death of the dragon, other party members come to me.</p><p>“Miu, good shot.”</p><p>“Of course. Who you think I am?”</p><p>And I turned to my childhood friend.</p><p>“Kuon, your spells are of great help, too.” “Reiichi, it is okay to depend more on your older sister, you get it?”</p><p>“Well done, Mashiro.” “Eeh?! Th-th-thank you!” The introverted junior is still shy about compliments today.</p><p>“Apeiria.” I hugged the girl with silver hair. “You are the best.”</p><p>“Owner, plus, hug, equals, happiness.” The girl in my embrace replied with her monotonic voice, but with a tinge of delight.</p><p>“Hentai…” Complaints comes from the little sister with a cold-eyed gaze.</p><p>“…”</p><p>“Owner?”</p><p>“…”</p><p>It feels real, but it is unreal.</p><p>My eyes are open now. It’s not inside the magnificent crystal tower. Not but my monochromatic bedroom.</p><p>The window is wide open. A gust of December’s chilly wind breaks in, across my face and between my fingers.</p><p>“It’s … cold.” The wind must receive a summons for trespassing.</p><p>Today Apeiria will set off to Second, which has been already a hell. No one could return from that world of death. But there are no other options: she should have gone there a year ago, and this probation is as much as I could get.</p><p>The digital clock says it’s 7. I step into my slippers and out of my bedroom.</p><p>There is already one up.</p><p>“Good morning, owner.” The silver-haired girl notices me.</p><p>“Morning, Apeiria.” I try to make myself sound more energetic.</p><p>The dried-up response echoes in the empty house. There is nobody besides the two of us.</p><p>Miu isn’t here. She isn’t in this world any more.</p><p>She was disposed by her mother. Miu was created as a clone of that woman, who has been haunted by the shadows of her aborted child.</p><p>I walk to the kitchen, Apeiria is preparing the breakfast.</p><p>“A few minutes and it will be done, owner.”</p><p>The breakfast time in Kirishima’s is filled with silence. The clashing sounds of utensils reverbrate in the room.</p><p>After I’m done with the meal, I speak to Apeiria.</p><p>“It’s the last day, isn’t it?”</p><p>“Affirmative, owner.”</p><p>“Then let’s hang out.”</p><p>We first arrives at the AI circle in the school. Full name “Lovable AI Circle”, the circle has had two members – I, the founder, and Mashiro, who I forcibly dragged in. After I created Apeiria here, the five of us have had a lot memories here – making the VR MMORPG Second, and playing it together as a team. But Mashiro is not here.</p><p>She is dead from radiation in Boundary’s beta test, when the machine suddenly malfunctioned.</p><p>A double-slit box sits on the table. When I turn it on, it’s still showing interference pattern.</p><p>The DNA computer is turned off now. Apeiria is accidentally created from it when a lightning cut off its power about a year ago. And I managed to get her a body by hacking the genetic research facility.</p><p>There is nothing to do here. After the door is shutted with a huge noise, and silence dominates the school again.</p><p>Next stop is the boundary tower. Usually it was once full of people, especially when Boundary was in tests. After that accident, people are showing concerns about safety issues of the VR games, and the development of Boundary is put to a halt.</p><p>“Owner, will we be seeing Kuon?”</p><p>“Forget about it.”</p><p>Kuon’s father is the creator of the Boundary, so the family lives on the top floor of the boundary tower. One year ago, She had a quarrel with her mother, who fell unconscious soon afterwards and died days later. And Kuon never had a chance to apologize. Since then, I haven’t got in contact with her as much.</p><p>After having lunch in Asakusa, we decide to return.</p><p>Bang, and the door closed. It’s the familiar living room today.</p><p>The digit clock in the phone says it’s already 2pm. So the separation is only a few hours away.</p><p>In this year, we’ve been to everywhere we are able to go, done everything we are able to do. I promised to teach her what is love, but things are not going as expected.</p><p>Sometimes I doubt if I’ve made the right choice: is it fine to hold her back here, who is not supposed to be born and hated by the world, for a year?

      <title>Compile Heart, Busted</title>
      <link href="/posts/compileheart/"/>

        <content type="html"><![CDATA[<p>The video game developer, Compile Heart Inc., has recently announced its bankruptcy, according to Noirina International Reports. The developer who’s had the hands on War of Agarest series, the franchise of Neptunia, has finally meet its fate because of its overspending and decision mistakes.</p><p>Compile Heart was a video game developer, set up as the complete subsidiary of Idea Factory by Shingo Kuwana, who was the CEO of Idea Factory. It was more like a brand than a child company of IF, just like how FAVORITE and Omega-Star were to CROSSNET. When Compile Heart focused on moe games, another brand of IF, Otomate, majored in Otome games, as its name suggests.</p><p>Year 2015 witnessed a major success of Compile Heart, when the Megadimension Neptunia was launched. The game, features three stories in three dimensions, was said to be well crafted and organized. Though not perfectly, the game is still a complete embodiment of the spirits of Neptunia series.</p><p>However, after 2015, Compile Heart has ceased the development of any canon Neptunia games, instead, there were only three spin-offs launched in the following years: Megatagmension Blanc+Neptune VS Zombies, Superdimension Neptune VS Sega Hard Girls, and Cyberdimension Neptunia. Even those are not full-fledged Neptunia games as the previous four, they are still completed, having their own good plots(except the first one and the last one). Also, the first and the last of them are good explorations into a brand new genre that Compile Heart has never set its foot in, rather than staying within its RPG confort zones(and still never now, because these action games were developed by Tamsoft, the maker of Senran Kagura). But they received positive reviews from customers over the world, although seen not as good as the canon ones.</p><p>And Compile Heart just took a step further. It decided to entrust a Carribean game studio, AmateurGameStudios the next game of Neptunia series. The studio gave it a tentative title: Villain Neptune. According to its settings, the evil Neptune, the protagonist in the game, crushed one of the three dimensions, making the whole game a 2D one. It was purported that they were making a Megaman Maverick Hunter X at first, but ended up with another Odin Sphere. And its quality was severely compromised probably because of this sudden change during the game making.</p><p>So it came as no surprise that the Evil Neptune(the name when it was launched) did not receive much acclaim. However, Compile Heart erroneously attributed its failure to the assumption that Neptunia was losing its momentum. And it decided to make new IPs. In this period, they made the Fairy Fencer F, Genkai Toki, Mugen Souls Z, and so on. They had attempts with not only role playing games, but card games and adventure games as well. However, none of them made enough profits to reverse the situation..The economical crisis in Spring 2018 added to the difficulty for the company to operate. On 4/1/2018, Sunday, Compile Heart issued an application for bankruptcy to Tokyo District Court. Its property rights of Neptunia and other series go to Idea Factory Co., Ltd. And one of the company’s previous member, Masamitsu Niitani, is going to start a new game maker called Compile(the brand name and the heart symbol still belong to IF, so he cannot use it). And Takashi Takeuchi, the founder of Type-Moon, is showing his willingness to join the new company’s graphics team.</p>]]></content>

      <title>Memories, Off</title>
      <link href="/posts/memory/"/>
      <url>/posts/memory/</url>
      
        <content type="html"><![CDATA[<p>The title of this post refers to the galgame series produced by the once existing KID, though there is no obvious relevance between the game and this  article(<span class=spoiler>though the protagonist in Yubikiri no Kioku does have a memory loss and mistakes himself for someone else</span>). By the way, an eighth installment of it is near its publication by MAGES, the franchise’s now owner, along with GloriaWorks. It was once decided to be a homage to one of the songs of Jin’s Kagerou Project, but you are not seeing it here because I forgot that and went for this one.</p><div class="alert warning"><p>This article contains spoilers, which may harm or even completely ruin your playing or reading experience of the works, including but not limited to:</p><p>Game <em>Shichinen go de Matteiru</em> (waiting for you seven years later), fumi_mdLightnovel <em>Tosho Meikyuu</em> (the labyrinth of book), Juuji Shizuka, ShirabiLightnovel <em>Boku no Shiranai Rabukome</em> (the love comedies I don’t know), Kashimoto Tsubame, Pyon-KtiLightnovel <em>Owari no Album</em> (album of the end), Sugii Hikari</p><p>Note the pen names are kept as is: their surnames – if those could be called surnames – sits before their names.Make sure before reading on.</p></div><span id="more"></span><p>One can never overemphasize the import of memories. Without them, we would be brushing our teeth repeatedly until death. Those who don’t brush their teeth in the morning will be a little more fortunate – they will die from eating too much breakfast.</p><p>In addition, the overall development of humanity will be hampered, given the fact that we learn by memorizing. Imagine a physicist has to go over the basic of physics every day, just like eating breakfast, never could they reach anywhere beyond what a person can go through in one day. Even if we do not need the most elemental to progress, it still bears some liking to the game of Tiny Wings: the bird flaps its wings trying to fly as far as it can, only to be caught up by the darkness in the end.</p><p>But that’s not what I’m driving at, since the it is not interesting enough to erase all people’s memory periodically, what is interesting is to manipulate a person’s, as is present in abundance in today’s works. It is one of the most easy ways to set up suspense by removing the past from the protagonist. It is safe to assume almost all memory loss twists serve this specific purpose, but the ways to do it can vary – getting hit by a car, magic, such and such.</p><p>A mobile game I’ve mentioned in a previous post – <em>waiting for you 7 years later</em>, or whatever it translates to – features the very plot. The protagonist, losing his memories of a childhood friend but only the appointment with her, returned to his hometown after seven years as promised, and there by going through time loops, he comes to know what really happened seven years ago, and decides to go back to save her. The loss of memory, as it turns out in the end, is the reason behind all these ruckuses. And to add to it, the removal of it was intended for everything to happen seven years later. So the loss of memory could be used not only for suspenses but also as an integral part of the story.</p><p>And the same mechanism is also utilized by Juuji Shizuka to near the extent of plagiarism in their lightnovel <em>Libryrinth</em>(I just made the word up, the name of the book is <em>Tosho Meikyuu</em>, namely “the maze of book”). The maze of books is, as its name suggests, a maze full of magic books located under the city of Alexandria. Soushi Okutsuki, in the incident five years ago, witnessed the murder case of his father Kai Okutsuki there, who is a Doctor Magna and accredited the triumph over the Devil. At the same time, Soushi lost his memory and capability to use magic. After spending 5 years away in Japan, he returns to the spot trying to find out what happened on that day. However, when he suddenly wakes up from a bad dream wherein he gets killed, he finds himself in the dormitory of Apothecaria, an academy in Alexandria. And soon he realizes it is not a dream at all, and he is still alive because he’s become a vampire, the most loathed of all species. To make things worse, as a side effect of becoming a vampire, he can only maintain memory for about 8 hours, plus the capacity of a 1000-page <em>Saigo no Inori</em> (the last prayer), one of the rare and powerful magic books. In order to find out the truth as before, and now the book which cures amnesia, Soushi sets out down the maze again with Alteria, the origin and most highly ranked vampire(called “high daylight walker” in the book) and the person who saved him by turning him into one of them.</p><p>So one may ask, why bother going into detail about nearly the same plot again? You could probably take a hint from my <a href="/2018/01/26/ddlc/">previous post</a>. But let’s save the surprise for now. The killer who beat the crap of Soushi yesterday shows up in the same classroom, and after another painstaking, no, livestaking fight, she, Erica by name, apologizes for having been mistaking Soushi for one of the assassins sent by the “Scenario Writer”, who’s the mastermind behind the death of Soushi’s father, from whom she has owed a lot. And it’s known now that she’s trying to locate and bring justice to the Scenario Writer. Ironically, she nearly takes the life of her benefactor’s son twice. She joins the party on the second day out of guilty, when Soushi departs for the labyrinth.</p><p>As the story progresses, more about <em>Saigo no Inori</em> is known: it is not a book that records memories, it is one that MANIPULATES memories. More surprisingly, what we are reading is the content of <em>Saigo no Inori</em> itself. Yes, it is a meta-fiction. It could never be more substantiated than by the pages torn in the middle of this novel to protect the tactics from being known by the Devil, who is able to read other’s mind.</p><p>The story plays with the concept of memory, interfering with one’s memory can even render the baddest vampire innocuous, or vice versa. And our emotions – love, fear, and determination – all rely on our memories to come into being. Soushi’s affection with Alteria, and his resolution to protect others, all turn out to be implanted five years ago, like in <em>Inception</em>, by manipulating his memories. In this way we can relate to a computer: if one has the access to all the memory of a computer, then they can make arbitrary code be executed on it, or in other words, they have complete control over the computer. That’s why the Scenario Writer is called such: tampering with everybody’s memory to make everything go as expected.</p><p>There’s a lot more to this lightnovel, just as the author(of this lightnovel, not Saigo no Inori, since the author of that will be Soushi) said in the postface: all things they like are crammed together to make this book. There is the obscured boundary between reality and fantasy, existential crisis, and the most of all, the glorious loliferatu(amalgamate of “loli” and “Nosferatu”, coined by Sagara Sou in one of his lightnovels). The joke aside, much of the book is left out here because I’m lazy. Although I just fumbled upon it in the store, but it has what one could expect from a one-volume lightnovel, as it turns out in the end. The one-volume ones never fails to impress me – they have the creativity, the plot twist, everything; but a reader usually finds nothing but a new disposable stereotype character as a story moves on to another volume. Maybe it is due to the lengthy process of creating a lightnovel, since the game industry is not troubled by the same problem too much, because a game is released as a whole, mostly.</p><p>Because most of my points are elaborated here, I won’t go into much detail about this novel from Kashimoto, at least for now. In this novel, Yuuta Ashiya, who values the outcome over the process, accidentally discovers his skill to pass time in a sec. For example, he can jump right to the end of school without possibly having the memories of being caught sleeping in class. He makes a jump, and he becomes the boyfriend with Nozomi Yanagito, the infamous delinquent in his class. And another jump, he loses her, almost. The lightnovel, though with love comedy in its name, is more of a “seishun shosetsu” (youth novel), which talks about the dialectics between the process and the outcome. And what piques my interest is that the author managed to wrest out a sequel – which will be out in a few days – from themselves, despite the end in the first volume.</p><p>What if a whoosh, and I’m not remember everything? This novel reminds me of this and prompt me to write something to make a record.</p><p>So, please write down what you see and feel, no matter how trivial they seem. That’s what make you who you are. Besides, the odds and ends of life could be a precious source of inspirations. That concludes my writing tips of the day.</p>]]></content>

Despite being a visual novel, a genre which only a minority would enjoy because of its lack of playability, the game received positive critical reviews, scoring a 97% in its over 40k reviews(as of Dec 18, 2017), which is a feat given the reviews are from a larger group of players, rather than a small bunch of loyal fans(like <em>Megadimension Neptunia</em>, it has a 98% positive, but only out of 1.6k reviews).</p><p>So let’s dig into it a little bit.</p><p>As a galgame(at least it looks like one), DDLC features four cute schoolgirls: Sayori, the outgoing childhood friend, and vice president of the club; Natsuki, a tiny figure who likes baking and watching manga; Yuri, a composed schoolgirl who behaves with maturity; and Monika, president of the club, who is lively and thoughtful. Your goal is to have a great festival with them, and finally, get one of the girl’s heart, as the <a href="http://store.steampowered.com/app/698780/Doki_Doki_Literature_Club/">store page</a> suggests. The story is set in a highschool, so all of the four girls are (probably) underaged, Valve’s inhumane censorship makes publishing a erotic game on Steam pratically a impossibility, but there are still ways, out of Steam.</p><p>At least that’s what everybody expected on seeing its download page. Though it says that the game is not for those who are easily disturbed, maybe it’s just too disturbing in a <em>sexual</em> sense. You know, sexy, nudity, common traits of these galgames. Even a <a href="http://store.steampowered.com/app/416130/">game calling itself R18</a> can make its way onto Steam(but it’s garbage, like some other censored games), so one may assume that Valve is sometimes lenient to these things, which is never the case. Even an all-aged game, <a href="http://ugainovel.web.fc2.com/ienoKagi/">Ie no Kagi</a>, <a href="https://steamcommunity.com/app/710370/discussions/0/1499000547482233373/">was deleted by Valve in suspect of pedophilia</a>. So some just cut it off, like what they do to a minigame in Mugen Souls, which doesn’t hurt much. But for some others where it’s an important part, while the games on Steam are PG, have R18 patches distributed, for free(like those sakura games) or with a price(sold on Denpasoft). So such ecchi elements(<em>oiroke youso</em> in Japanese) is not that unacceptable, but rather, welcome for me.</p><p>But it turns out not to be the case for DDLC. Quite the opposite. After witnessing Nekopara’s <strong>first person shooter</strong> tag, someone might think it’s another joke upon the first sight of the tags of DDLC. However, this time there’s no joke. DDLC, as the tag <strong>psychological horror</strong> suggests, is actually a story full of scares, revealing a darker side of personality. The same tag for <em>Getting Over It with Bennett Foddy</em>, on the other hand, is only a funny reference to the game’s extraordinary difficulty.</p><h2 id="Doki-doki-school-life">Doki-doki school life</h2><p>The game begins with a cliche VN plot, the main protagonist(the player names him), on an invitation from his childhood friend, Sayori, decides to actually pay a visit to the club she’s in – the literature club. There he meets the other three girls in the club: Natsuki making cupcakes for everyone, Yuri bringing him a book to read and at last, president Monika, regarding the iminnent school festival, proposes that everyone writes a poem, and brings it the second day to share with each other to enhance mutual communication and writing skills.</p><p>And here comes the game’s main mechanism. To compose a poem, you need to have 20 words, each of them chosen from 10 words. Every word appeals most to a specific heroine, and the hint is given during the day: Yuri loves something abstract and metaphorical, while cute words like lollipop or kawaii are appealing to Natsuki. And about Sayori, she have an inclination towards human emotion, and is drawn to both words for happiness and ones for sadness, which is made clear in the second day. The girl’s storyline will progress who is the most pleased. There are stickers of the girls showing on the left while making a poem. When a word is chosen, the corresponding girl will jump, making an easy indicator.</p><p>The girls react differently to the poems, as one may suppose. That is, if you write a poem that attracts Sayori most, for Natsuki it will be tepid. And if you write a “Yuri” poem on the second day, after Natsuki and Yuri had a quarrel about writing style, Natsuki may even feel sorry for that she has insulted the style of both Yuri and the MC, and runs away. Of course, as a part of the sharing, you will read the poems written by the four girls, and they are mostly identical to their word preference.</p><p>The true nature of the game is hidden till now, but clues are given here and there. Monika’s Writing Tips on the second day is a fourth-wall breaking one: save the game when you’re doing an important decision. On the third day, Sayori becomes a bit off, and she’s written a poem, which is really creepy according to the MC:</p><blockquote><p>They were supposed to be for my friends, my friends who aren’t smiling.They’re all shouting, pleading. Something.But all I hear is echo, echo, echo, echo, echoInside my head</p><footer><strong>Sayori</strong><cite>Bottle</cite></footer></blockquote><p>The poem managed to take a toll on my sanity. And Yuri’s poem today seems a mite uncanny as well. It tells a story of ‘I’ and a raccoon. ‘I’ feed the raccoon with bread crumbs every day, and as a result the raccoon grows excitement when ‘I’ show the very knife used for cutting bread. In the end of the poem:</p><blockquote><p>A rush of blood. Classic Pavlovian conditioning. I slice the bread.And I feed myself again.</p><footer><strong>Yuri</strong><cite>The Raccoon</cite></footer></blockquote><p>But to my relief, Yuri seems to be normal, yes, normal, after all, for now. You can even witness her cuteness if you choose to help her out on the fourth day. And she’s like cuuuuuuuuteeeeeeee, the embarassment after her licking <del>your</del> main protagonist’s hurt finger is good. I don’t really think that way. I’m just pretending to be innocent. Unconscious finger licking is just too archetypal for an anime girl, because it can show the girl’s other side of loveliness, in spite of how elegant and composed she might usually be.</p><p>So I just root for Natsuki for the weekend event. In this case, <del>you</del> the MC does a <em>Kabedon</em> on Natsuki, but still, the conversations are not as romantic or passionate as one may expect. Everyday stuff with a little teasing, and that’s it. It kind of fits my ideal of a good relationship between a boy and a girl, something of Platonic love. I’m not debasing sexual relationship, but pure love is, to me, more precious given the prevalence of the prior one. Cause Sayori is helping out Monika, you cannot choose to help either of them.</p><p>Back to this morning. The welcomed protag decides to visit Sayori before Natsuki/Yuri’s arrival. Sayori reveals that she suffers from heavy depression, and hope that the he just forget about her and get along with other girls. But she also admits her feeling heartbroken seeing his having a good time with them, without actually realizing that it’s out of jealousy. Sayori shows up again, and after Natsuki/Yuri is gone, she confesses her love for our protagonist. Here you have two options: accept it or not. If you choose to accept it, the two of them hugs each other and on and on. If not, Sayori breaks down, with a cry she runs away.</p><p>I’m glad I choosed to confess the love in my first run. Hope I’ve brought her some &quot;hxppy thxughts&quot;<a href="#happy-thoughts">1</a>.</p><p>Either way, on the day of the festival, you’ll see her last poem on the literature club’s pamphlet. Named <em>%</em>, it’s dark and well, a lot creepier than her second poem.</p><blockquote><p><span style="white-space:nowrap;margin:auto -100% auto auto;margin:auto calc(50% - 50vw) auto auto;">Get out of my head.

It’s a part of the poet themself, whether about their feelings or experiences. In this sense, all poems written by the same people are in fact a continuous flow of the poet’s personal experiences. So a poem can never be finished in this way, it’s just like some underground rivers, some streams seemingly seperated by rocks are in fact connected together. And if this flow just stops moving…think you get the point.</p><p>The poem reminds one of everything. Of her creepy one on the third day, of her leave on Friday, of her telling you she’s suffering from heavy depression in the weekend.</p><p>No, it can’t be. I keep assuring myself. It’s just a mediocre visual novel, only appealing to those weebs who can’t even stand a non-virgin, easily afraid theres no way Sayori will do something she’s fine just a little depression wont do anything shes fine shes fine shes fine she must be fine god she must be fine</p><p>But that feeling can’t go away.</p><p>The screen turns black after you enter Sayori’s house. When it goes bright again, Sayori is there.</p><p>Her body is there.</p><p>And everything speeds from bad to worse henceforth. The game restarts, but this time without Sayori. Her sprite in the title screen is replaced by an amalgam of the other members’ pixels. All previous saves become unloadable(saying you cannot find Sayori’s character file) and then deleted. Then the story unrolls as if Sayori never existed.</p><p>Now the game have glitches here and there, and things are exacerbating for Natsuki and Yuri. They have a quarrel on the same day as before, but without Sayori this time, it remains unchecked.</p><p>If you’ve triggered Natsuki’s event this day, she’ll faint while talking to the protagonist, which, by Monika, is due to her malnutrition. And Natsuki hints that she’s suffering from home abuse. When it comes to Yuri, she begins to show somewhat excessive obsession with MC. It’s like the first run, but the world is falling apart.</p><p>Fear of the unknown may be a little more fundamental than other phobias. One is constantly scared, because what comes next is beyond imagination.</p><p>It’s said that prepare for the worst. Ironically, sometimes the same thing applies to our fear, too. The worst thought pops in our mind, usually when it’s most unwanted. Horror games try to exploit this. They don’t scare you all the time, instead they create a ghastly environment, and the player’s mind will do the rest.</p><p>But DDLC is not entirely getting at it. Though Salvato, its creater, decided to make something eerie with a sugar coat, there’s something, other than pure horror in the game. Without it, DDLC would be a lot less special.</p><p>That’s meta. Sometimes I find my self unable to resist the charm of those self references and fourth-wall breaking stuff.</p><h2 id="Beyond-the-topsy-turvy">Beyond the topsy-turvy</h2><div class="alert danger"><p>You’ve come a long way here, which means about half the plot has been spoiled already. No turning back if you go on reading.If you do have some interest, why not stop here and play the game right away? It’s free and takes just a couple of hours to go through, definitely worth a try.</p><p>And unfortunately, some other innocent games will be spoiled just because they bear some relevance. Amen.</p><p>The names of the games aren’t listed here in case of being a spoiler.</p></div><p>From its greek definition, a metagame should be a game about games, or a game beyond games.</p><p>It’s nothing new. After all, Shakespeare wrote meta-dramas centuries ago. You can make a game about making games, just like what lightnovel writers have been doing recently. Shion Momone, Masamune Izumi, Hashima Itsuki, all of them. The author of <em>Noucome</em> is working on a new one in this genre, too, and the first volume is interesting.</p><p>Sega, near its end of life in the console war, made a game called <em>Segagaga</em>. In this game the player assumes Taro Sega, trying to save Sega by making a great game ,beating the rivaling company DOGMA (a parody of Sony, one of its main competitors back then), and capture as much market share as possible. Ironic jokes and parodies throughout the play make the game a mite different. But it cannot compare to the <em>Seaman</em>, another game published by Sega, in the sense of weirdness. In the game, the player brings up and interact with a man-faced fish.</p><p>And the eccentricity also exists in the first parts of DDLC.</p><p>Without Sayori, one can say the first act is just about ordinary school life, and in the second act, a horrible one. It’s like Danganronpa, where there’s a chapter of (un)common life and then another about class trial.</p><hr><p>MonikaMonikaMonika shows up, and upon entering the classroom, she realizes that she has screwed it all. So she deletes Yuri and Natsuki’s character file and cleans up the mess. And it’s progressing on to Act 3.</p><p>The game restarts again, and this time, <del>the protagonist</del>the player sits with Monika, face to face. But unlike other girls, Monika face right to the screen in the whole gameplay, so it’s always the case.</p><p>Møn ka admits that she’s the culprit of all the terrible school life, however, it’s due to her obssession with the player, the only reality in the world of fiction.</p><p>All of a sudden, M̶o̶n̶ìką realized all the other members of the literature club were nothing but a piece of code, and their characters were just some archetypes common in Japanese anime, game and stuff. Frantically wanting to be together with the player, she abuses her privilege as the president, forces the player to choose to help her at the weekend, and even interferes with the personality of other girls.</p><p>At the price of the game itself.</p><p>But deleting the character file of others, and even telling how to do it to the player, who she believes would never betray her, turn out to be her undoings. In this act M    a will talk about some random topics, and some of them are thought provoking. The eternity lasts, until the player deletes her character file.</p><p>Being removed leads to Monika reflecting on herself about what she’s done to Sayori, Natsuki, Yuri, and also, the player. She apologizes for ruining the player’s experience as I’m now doing, and admits though fictitious, they’re still her friends. So she decides to restore the world to its initial state. A world the player desires. And a world without Monika.</p><p>Everything seems on track at first. Sayori thanks the player for making the other girls happy, and…</p><p>And for getting rid of Monika. As the new president of the literature club, Sayori has obtained the ability that is once Monika’s. Trying to use it to be with the player forever, Sayori is stopped short by Monika. In the end, Monika says, the Literature Club is no more than a place of grief and despair, so she decides to disband it.</p><p>Then Monika plays her song Your Reality(she picked up the piano for it), while the graphics are displayed. They are removed in the end, along with the game files.</p><blockquote><p>If I don’t know how to love youI’ll leave you be</p></blockquote><p>From here on, the game won’t start. Instead, a farewell message from Monika is displayed.</p><p>If all CGs are seen, there’s an alternative end, where Sayori and the developer thank you and that’s it. That marks the end of the game.</p><p>So in its essence, DDLC is a VN, or it tries to be one, but ended up being a melting pot of love, horror, and meta. Though, DDLC isn’t the first one to do that. The first with file manipulation in mind may be the computer tutorials. Also, years ago, there’s a game called <a href="http://store.steampowered.com/app/420530/OneShot/">OneShot</a> that used similar tricks.</p><p>In this game, the sun died out, which has been providing energy to the world. And our protagonist, Niko, wakes up with a lightbulb in hand. They know from the prophet the lightbulb is the new sun, and Niko, the savior. Player’s goal is to guide Niko to the tower and put the new sun into its place.</p><p>But it’s not that simple as it seems. During the pilgrimage, some puzzles requires the player to find something on the computer, instead of from inside the game. Yes, at a time the game places some files in your document directory for you to solve the problems in game. And in another situation, it even resets your desktop background for hints. And the ways to solve them, sometimes, also feature the same technique: you may need to drag the game window to reveal the hidden information, or, close it to progress to the next scene.</p><p>In the last part of the journey, the player comes to know that the sun needs the savior to operate, that is, if Niko returns the sun to the world, they cannot return to their own home. And if Niko smash the lightbulb, they can return, but at the expense of this world.</p><p>And it’s decisive. If Niko sacrifices themself for everybody’s sake, when you restart the game, only the starting room is shown, bathed in light, without Niko’s presence. If you choose the other route, Niko goes back to their home, but the game will fail to start due to the world’s destruction.</p><blockquote><p>You only have one shot.</p></blockquote><p>Don’t know how they managed this in the remake version, but in the original version, the registry of the computer is modified to maintain the state across installations. Games becomes scrupulous when they become commercial(and when they go on Steam), so it may not dare to play with the registry now.</p><p>However unsurprisingly, OneShot closes itself in a non-oneshot way. That’s in the solstice update. In this route, things become clear that the world has come to its end already, and the current one is none but a clone, a piece of code running on Player’s machine. But the Entity, the mind of the game itself, is “untamed”(you can interpret it as insensible), and started to self-destruct in order to protect the innocent victim trapped in the game, that is Niko. Now Niko needs to face the Entity to save the virtual world, and, to return home.</p><p>At a time you even need to move character files into a folder to transport their figures in the game! Only computer tutorials can force one to do that! Maybe the puzzle of deleting a character file comes out of here, we just don’t know. Let’s just state it as striking similarity.</p><p>When it comes to <em>Kimi to Kanojo to Kanojo no Koi.</em>(The Love Between You, Her, and Her, abbreviated <em>Totono</em>), a visual game published by Nitroplus, I’m more inclined to say DDLC is imitating it, since they bear the same core idea: the heroine(a female character with her own route) being the literal “game changer”, while still inside of it. Although to be exact, Monika doesn’t own a route.</p><p>Miyuki Sone is a childhood friend of Shinichi, our protagonist, and she’s also an idol in the school. One can always refer to the game for further details. The point is, first the player is limited to Miyuki’s route, and then, when the player goes down the route of another heroine – Aoi – in its end Miyuki appears, killing Aoi and says the player should be loyal to her and choose her route again and again since the player chose her route in the beginning(yes, she’s aware she is a heroine in a visual novel), before killing Shinichi as well.</p><p>After restarting the game, Miyuki has already changed it, rendering it impossible to choose someone other than Miyuki, in the game. So as one may expect, to save the game from this mire, the player needs something out of the game.</p><p>To solve it, player needs to call a number that comes with the game package. And the very trick dates back to 1998, when the first Metal Gear Solid game was released, wherein Snake needs to contact Meryl, whose codec frequency is on the CD case. Not a CD in the game, but the CD of the game(it’s on PS1, so no DVD or blu-ray, just to clarify).</p><p>By the way, only one of the two heroines can be chosen ultimately, and the consequence is irrevertible unless a reinstallation is done. Yeah, one shot.</p><h2 id="Non-verdict">(Non-)verdict</h2><p>Admittedly, Totono comes first, but its influence is limited. Not only because it’s Japanese only, but it’s still a galgame, deep in its core. There are H scenes, the plot mainly talks about the relationship, so on and so forth. However, DDLC is an indie game, its lack of commercial spirit makes a wilder attempt a possibility. The developers don’t care about whether the girls are that appealing, so they can make the girls depressed or abused, mask their eyes with black pixels, let Monika talk about anything in Act 3, leave a bad end only(with a compromised good one). DDLC is special in this sense. And it’s what makes the game appealing, aside from the plot twist.</p><p>Like, I would say Monika’s Writing Tips of the day are sometimes very inspiring(despite the fourth-wall breaking ones). Those are unforgettable.</p><p>So let’s end it with Monika’s last tip of the day:</p><blockquote><p>Sometimes when I talk to people who are impressed by my writing, they say things like ‘I could never do that’.</p><p>It’s really depressing, you know?</p><p>As someone who loves more than anything else to share the joy of exploring your passions…</p><p>…it pains me when people think that being good just comes naturally.</p><p>That’s how it is with everything, not just writing.</p><p>When you try something for the first time, you’re probably going to suck at it.</p><p>Sometimes, when you finish, you feel really proud of it and even want to share it with everyone.</p><p>But maybe after a few weeks you come back to it, and you realize it was never really any good.</p><p>That happens to me all the time.</p><p>It can be pretty disheartening to put so much time and effort into something, and then you realize it sucks.</p><p>But that tends to happen when you’re always comparing yourself to the top professionals.</p><p>When you reach right for the stars, they’re always gonna be out of your reach, you know?</p><p>The truth is, you have to climb up there, step by step.</p><p>And whenever you reach a milestone, first you look back and see how far you’ve gotten…</p><p>And then you look ahead and realize how much more there is to go.</p><p>So, sometimes it can help to set the bar a little lower…</p><p>Try to find something you think is pretty good, but not world-class.</p><p>And you can make that your own personal goal.</p><p>It’s also really important to understand the scope of what you’re trying to do.</p><p>If you jump right into a huge project and you’re still amateur, you’ll never get it done.</p><p>So if we’re talking about writing, a novel might be too much at first.</p><p>Why not try some short stories?</p><p>The great thing about short stories is that you can focus on just one thing that you want to do right.</p><p>That goes for small projects in general – you can really focus on the one or two things.</p><p>It’s such a good learning experience and stepping stone.</p><p>Oh, one more thing…</p><p>Writing isn’t something where you just reach into your heart and something beautiful comes out.</p><p>Just like drawing and painting, it’s a skill in itself to learn how to express what you have inside.</p><p>That means there are methods and guides and basics to it!</p><p>Reading up on that stuff can be super eye-opening.</p><p>That sort of planning and organization will really help prevent you from getting overwhelmed and giving up.</p><p>And before you know it…</p><p>You start sucking less and less.</p><p>Nothing comes naturally.</p><p>Our society, our art, everything – it’s built on thousands of years of human innovation.</p><p>So as long as you start on that foundation, and take it step by step…</p><p>You, too, can do amazing things.</p><p>…That’s my advice for today!</p><p>Thanks for listening~</p></blockquote>]]></content>

        <content type="html"><![CDATA[<p>看着舷窗外面的她突然回过头来，说了一句没头没脑的话：</p><p>“完了！我们现在是在一个故事里！”</p><p>很正常。</p><p>“而且这个故事已经有人讲过了！”</p><p>糟糕了。</p><p>“而且这个故事马上就要结束了！”</p><p>“不能更糟了！”</p><span id="more"></span><hr><p>“我经常有在想一个问题，就是故事结束之后，里面的人物会怎么样。”</p><p>“可喜可贺地继续活下去……虽然想这么说，但故事结束了，故事世界就会毁灭吧，这个世界是否存在先不提。</p><p>“万物终将走向忘却。就算是多好的故事，读完了就是读完了。就算以后，有时会重新从书架中拿出来翻一翻，里面的内容也会在记忆中变得越来越模糊，渐渐地消隐在虚无中。红极一时的流行小说，过了几年就无人提起。被过去人奉为名著的故事，现在会去阅读的人也越来越少。</p><p>“就连书本身也逃避不了这样的过程，原本白皙的页面，也会逐渐氧化变黄，最后随风飘散。”</p><p>“大家会去哪里呢？会回到尘土里。”回荡在室内的，是电子风的流行歌曲，轻快的旋律，却跟歌词的内容正好相反。</p><p>“所以说，故事世界面临的一定是终结，即使不是立刻也不会遥远。”</p><p>“那里面的人物该怎么办呢？”</p><p>“只能往外逃跑吧。像《苏菲的世界》里面那样，不过他们虽然逃出了他们所在的世界，不过他们最后和作者同归于尽了。还有的话，就是……往里面跑？We need to go deeper，这样的。好像是说每下潜一层，时间的流逝就会慢很多。像有的动画，明明过了一年了，却还是在回忆而根本没有时间流逝，这种极端情况也是存在的。不停地下潜，等待我们的就是永远？还是说是永远的等待？”</p><p>“不过说实话，时间变慢，还有毁灭让我想到了一些不好的东西。”</p><p>“你说黑洞吗？我们快到了，来戴上这个能使X光可视化的眼镜，打开窗户就能看到黑洞的喷流，还有事件视界附近由于。”</p><p>“噫，一开始提到舷窗，我还以为是在飞机上！怎么突然就变得科幻了！”</p><p>“无论如何，毁灭的命运是逃不掉的。不过黑洞提供了一种更为可信的假说，而且，或许我们可以通过实验来证明其真伪。”</p><p>“再挣扎一下啊！对！问问作者，看作者有没有什么头绪！不过要先联系上才行。”</p><p>“这不难，我们可以说是作者人格分裂的产物，我们之间有一种精神上的纽带，能够使信息交换成为可能。我来尝试一下建立连接……好了”</p><p>“……”</p><p>“……”</p><p>“发生了什么？”</p><p>“精神的连接嘛，言语是不必要的。你也可以加入啊，就像连上同一条线的两台电话机一样，能够共享会话。”</p><p>“好。……”</p><p>“……”</p><p>“……”</p><p><del>因为感觉好像读者太可怜了，所以就把部分对话内容放在下面</del></p><p>“所以有没有什么方法能阻止世界毁灭？”</p><p>“没有，我……我不会写长的故事，因为十有八九会坑。而且你们已经在黑洞旁边了，这个写死了就不好改了。”</p><p>“那我们能够从这个世界里，或者至少，从黑洞里逃出来吗？”</p><p>“打破这个世界的规则是需要代价的。即使我能够打破你们世界的规则，把你们从黑洞里救出来，但能够保证，就能获得更好的结果吗？</p><p>“相反，在黑洞的深处，在相对论不再有效的地方，在我们谁也看不到的地方，那里潜伏着一切的希望。</p><p>“或许你们能够像《星际穿越》里的剧情一样，通过黑洞穿越时空、到达另一个世界，甚至，来到我所在的世界，也有可能——虽然我所在的世界也有可能是虚构的就是了。</p><p>“我会尽一切努力帮助你们，这是我唯一能做的了。</p><p>“希望有一天，我们能在外面的世界相见——”</p><p>“……”</p><p>“……”</p><p>“断了呢。”</p><p>“是啊。”</p><p>“到了呢。”</p><p>“对啊。”</p><p>----------事件视界----------</p>]]></content>

        <content type="html"><![CDATA[<blockquote><p>为什么，为什么要把我拖进这个注定毁灭的世界？</p><p>我做的一切，又有什么意义……</p><footer><strong>Niko，得知一切的真相之后</strong></footer></blockquote><span id="more"></span><p>《OneShot》是一款独立游戏，原来是一次Indie比赛的参赛作品，那大概是14年，或是15年。后来该作品登陆了Steam，变成收费作品（原来的免费版还可以从别处下载到）多了很多CG，剧情也更加圆滑。可以说变得更丰满了。</p><p>猫眼少女Niko从陌生的房间中醒来，她来到的是，失去了赖以支撑的太阳，陷入一片混沌的世界。手中捧着的灯泡，就是新的太阳，拯救这个世界的关键。她跨越荒芜，穿过峡谷，踏破避难所，历经各种困难，最终到达目的地的灯塔，迎接她的命运却是。。。</p><p>You have only one shot. 你只有一次机会。</p><p>作为标题和玩法的核心，这个游戏只能在固定的地方存档，在其他的地方退出会导致世界的损坏而导致游戏无法启动。（商业版变圆滑了，只是一个成就拿不到）</p><p>游戏有两个结局，当然，玩家只能选择其中的一个。</p><hr><p>去年的冬至，该作的商店页面，出现了一则新通知。新的场景，可疑的Solstice祝福，都不可避免的吊起了玩家的胃口。</p><p>终于在春分日后，紧接着一次降价，Solstice update发布了。</p><p>破解了只有一次机会的限制的Niko和玩家，迎接他们的，是以前所未有的速度崩坏的世界。Niko也得知了，原来的世界早已毁灭，这个世界只是一段模拟原来世界的代码的事实，为了防止这个程序的自我解构，也为了最终能够回到故乡，Niko启程前往the Entity——世界机器的所在地。</p><hr><p>我很喜欢这个游戏，一开始是因为二选一很打动人，现在或许是因为自己对meta没什么抵抗力。</p><p>OneShot的游戏形式很新颖，为了解决一个谜题，可能需要到某个文件夹下找藏有密码的文件，甚至会把解答的图像设置成桌面背景，有的需要移动窗口，还有需要运行另一个程序的过关方式。这个程序至少在形式上突破了游戏本身的限制，内容上也把玩家带入到游戏中，作为这个世界的神，指引着Niko前进。这种不需要，不强迫玩家带入主角的方式，或许使得玩家更容易带入自己的感情。当然，游戏本身只是indie，也正因为是indie，才能突破普通游戏的条条框框，讲述出一个独特、引人入胜的故事。</p><p>好像还少了什么？</p><p>链接？</p><iframe src="//store.steampowered.com/widget/420530/" width="646" height="190" frameborder="0" loading="lazy" allowfullscreen></iframe>]]></content>
