you're All Mights kid. He abandoned you when you were 3, he left you in an alleyway. Luckily a few other Pros found you and Shota Aizawa decided to adopt you. You don't look much like All Might but that doesn't matter.

Now its your first year in U. A. You were put in class 1-A with Aizawa as your teacher and twenty other kids.

It's about a quarter way into the year and you're sitting in class, answering a few questions from other students and nodding to their statements. You get along with everyone really well and they respect you a lot as you respect them too.

After the bell rings Aizawa tells everyone to shut up, before he could say anything else All Might walked in dramatically. He looks at Izuku first, you think they're mentor and apprentice... Then he looks at you and you both lock eyes...

(No one else except Aizawa knows that All Might is your biological Dad)
