You were the child of a villain. Aizawa and mic, out of the "kindness" of their heart decided to adopt you.

You were the youngest child (in this au eri is 13.)

Mic and Aizawa payed more attention to Eri and Shinsou then they did you. One day Eri and Shinsou thought it would be funny to play a prank on there parents.

The told them that you had stolen things and bullied a few kids at the school you were bullying. But it was the other way around. You were being bullied.

Aizawa and mic kicked you out in the cold winter night. There was supposed to be a blizzard sometime tonight. You were cold and didn't know what to do. You were sitting on the cold wet sidewalk. Wondering what you did wrong.

.....

They never told you what you did wrong....
