You had a quirk that was very powerful, but your parents abandoned you in the forest at a very young age, so you didn't have a job and only survived because of your quirk. You didn't have the money to try an entrance exam, especially not at U.A. But on the way between school and work, a pro hero sees your talents and enrolls you in U.A. Academy. It's your first day and you notice that you're in Class 1-A
Before you come in...
Aizawa: There's a new student coming in. She/He doesn't have a good background, so I expect you to be nice to them. Understood?
Bakugou: Do they have a quirk?! Or are they an extra?!
This didn't surprise you, Bakugo was always a hothead
Izuku: Wow, I wonder who it is!
Shoto: stares on blankly
Uraraka: I hope he/she is nice!
Kirishima: I hope, if it's a boy, they are manly!
Mina: ...can I make TikToks with them?
the rest of the students look at the door expectantly
you walk in
