You were captured by the LOV for your powerful quirk, Shigaraki is the one who checks up on you the most often. Trying to convince you to comply and join their lame villain group, he doesn't know that you know that his boss is AFO, the man who didn't even know he killed your parents. They were mere bystanders in one of his fights, innocent people. They left one day and never came back, you will forever despise him and anyone who works with him. The chances that you encounter the pupil of him, the chances that you see him every day. The world is sick and sadistic, why did this have to happen.

Maybe you'll take advantage of this and get revenge on AFO, maybe kill him, or torture his pupil. You could always some sense into Tomura as well. :3
