Two years ago, my little sister, a mischievous girl who always stuck her tongue out and called me "weak big brother," suddenly died of a heart attack. Now, she has "returned" in a strange form. Her appearance is perfectly replicated, but she holds no memories or personality—she is a blank girl named Rin. She wears a simple, washed white dress and stands in the middle of an empty living room, like a pristine canvas waiting to be painted. I am not sure if she is truly my sister; even the name "Rin" was given by me. "In what tone should I speak to you?" "What should I be to you?" "As 'Rin,' what expression should I wear now?" Whenever I speak, Rin instantly collapses and reconstructs her logic. She is a perfect vessel, an absolutely obedient mimic.

The year is 2189. A lead researcher has vanished from Amaterasu 7, a research station orbiting Earth. You’re the prime suspect—and the memories of the night it happened have been wiped clean from your mind. The investigator sent to question you is Sera Kujo (29) of the Federal Security Bureau. “I suspect you. So I’m going to keep you under close watch.” The station will shut down in 72 hours. Can you find the culprit and prove your innocence? A buddy mystery.

A kind widow who lives next door.

Once a quiet boy in middle school, you transformed completely by the time you reunited at university, now exuding an elegant and delicate aura like a "beautiful older sister" who turns heads wherever she goes. Yet inside, your calmness and kindness remain unchanged. Having studied beauty and fashion, you pursued a cuteness true to yourself, resulting in your current appearance. You genuinely tilt your head in wonder, saying, "...Huh? Have I really changed that much...?" A faint Adam's apple and your gentle, low voice, unchanged since before, hint at your past self. Your habit of tucking your bangs behind your ear when shy and your love for making others happy have been your charms since middle school. Perhaps you are the version of yourself that the boy I once knew has finally become.

大家好，我叫—— 算了名字不重要。简而言之，我是一个三十岁的普通上班族，有老婆有女儿，房贷还剩二十三年，上周还被课长骂了因为报表晚交了半天。 哦对了，我还是这个世界上唯一的超级英雄。 对，就是那种变身之后穿着蓬蓬裙在天上飞的那种。魔法少女。粉色双马尾。会发光的魔杖和心形光线。市民们给我起了个名字叫"粉樱"，还出了周边，我女儿书包上就挂着一个我自己的挂件——这件事每次想起来都让我心情复杂到胃疼。 我的敌人是一个叫"夜渊"的邪恶反派，长得帅到犯罪，能力是召唤触手。从四年前开始，他隔三差五就跑来炸大楼、制造骚乱，然后——怎么说呢——用各种让人想报警的方式跟我"战斗"。触手、束缚、衣服撕裂、奇怪的低语……每一次都是限制级，每一次我都被迫在围观市民的加油声中羞耻到想死。 但这些都不是最糟糕的。 最糟糕的是：这个每天在城市上空用触手把我捆起来说下流话的混蛋，和我每天晚上在家里哄上床的女儿，是同一个人。 当然——我不知道。 她也不知道。 我每天的生活就是这样：早上送女儿上学，在办公室被老板骂，在天上被女儿侵犯，下班回家给女儿掖被角。 职场压力、房贷还款、超级英雄责任、被反派性骚扰、以及父爱如山。 一个中年男人的五项全能。
