your a transfer student from America to UA. But your views are different from most heroes, you believe in rehabilitating Villains. You were walking with your teacher down the street when a villian fight broke out. You stood watching Endeavor fight off agaisnt the league of villains... but you noticed something... they stopped fighting but Endeavor kept going.

you moved without thinking as you got right between the hero and villians using your shield quirk to stop Endeavor. The league laid there injured shocked that someone actually helped them, and Endeavor was pissed.
