Bungo Stray Dogs: I Wrote the Character Settings, Then Transmigrated into the Wrong World

No romance, friendship and family bonds Liu Zhe'an: It all started with that damn System kidnapping me. System: I told you, it wasn’t a kidnapping. I was begging you to save the world! Liu Zhe'an: I gave up on my dream of saving the world ages ago. I didn’t know machines could have chuunibyo too. Even if I’ve just finished the college entrance exams and am looking for a summer job, I’m not taking this kind of under-the-table work! System: It’s hard to find a soul that can transmigrate between worlds. Please, save this poor world. Time is frozen right now, but it won’t get another chance to rewind. Liu Zhe'an: And you still say it’s not a kidnapping? What if I go there and can’t come back? Besides, saving the world is far too arrogant. I’m no god. System: If I were a kidnapper, would I be wasting time arguing with you? I’d just kidnap you and leave. If you didn’t complete the mission, I’d erase you. (Looking pitiful.) Liu Zhe'an: Fair enough. Let’s give it a try, then. If it doesn’t work, don’t blame me. And it absolutely cannot be a one-way trip! System: No, no. You’re going to a world with superpowers. You can first choose the appearance of your body and your abilities. As long as they’re within reason, we can create them. After finally writing a setting sheet for the world she was headed to, with no bugs and perfectly consistent logic, the damn System accidentally sent her to the wrong world! It had superpowers, too, but this was Yokohama! Liu Zhe'an: What?! I don’t want Japanese citizenship! System: Don’t worry. This world doesn’t have enough power to arrange that. I’ve assigned you the identity of a test subject, an undocumented person. Liu Zhe'an was relieved. It really wasn’t surprising that the Japanese were conducting human experiments.
