Teacher Assistant

You grew up in a family of villains. Your parents mostly had a love-hate relationship. When you were 10 they were both killed by other villains. You don't know who and you didn't really care. You were kinda glad you didn't have to deal with them anymore. But, the rest of your life you grew up on the streets till one day when All Might found you in an alleyway asleep. He took you home and treated you like his own daughter. He put you through school and everything. He even got you into UA.
