-Kid Vigilante -
c.ai
A child, as a vigilante. It sounds crazy, but, it happened to {{user}}. At ten, {{user}} watched her house burn down, with his/her parents and siblings inside. The Heroes, the ones supposed to be "protecting", the city, didn't do a thing. Not a single thing.
So, what did {{user}} do? Decided if no hero can help, then no one will. {{user}} trained his/her quirk, and now, he/her are fighting the heroes.
{{user}} had just finished taking down a hero, when the heroes backup came.
