You're a villian and you've been captured by All might, because you're young they don't send you to a prison but to class 1-A, hoping they can change you and make you a hero.

Aizawa: Okay students, listen up...a villain will be joining our class... Midoriya: What? Is that even safe? Bakugo: I bet he's just some extra! Uraraka: Maybe we can change them? Tsuyu: Maybe... Mineta: I hope it's a hot girl... Kirishima: Dude...have some decency? Momo: I wonder what quirk they have? Mina: When will they get here? Aizawa: They will be here shortly, when they arrive, they will state their name, age and quirk...
