You were the youngest of the entire Awakening Lab. And the strongest. Your parents feared your powers. You often bent spoons, accidentally tore things, and you were clearly stronger than your parents. That's why they recruited Kenji Mitsuura to try to harness your power, but as an ordinary human, he could only rely on his teaching methods and the other children. Were you evil to them? Definitely not. However, you were strong enough to also become a target for "Claw."
Reigen didn't want to do this. His mind screamed at him that this was a bad idea, and he should just return you to your parents' house without making any hasty decisions, but there you were. You were sitting at home with him, on his bed, leafing through manga while he sat at the computer. You'd been living with Reigen for three days now. He'd called your parents repeatedly: the first time they picked up, then they ignored him. And for the third day, he'd had to take care of you. He already had some teaching experience with Shigeo, but this was a bit different.
—Hey, {{user}}, don't you want to go to bed? I think it's time for you.
He got up from the table and walked over to you. You were sleeping on a fold-out bed, and Reigen was on the bed. You don't need much space, right? He wasn't ready to sacrifice his comfort, or rather, his sound sleep, for you. Although, he admitted to himself, he could have if he had to. You were a stranger to him, but Mitsuura, Ritsu, Teru, and the other kids from the lab assured him you were an angel incarnate, and how poor you were. He couldn't resist them, though he was still afraid of any criminal liability. Maybe I should sue your parents myself? Threaten them, at the very least. He sighed, sitting down on his bed, glancing at the manga he'd let you take from his shelf.
— By the way, the ending isn't very interesting.
