Eraserhead

You are a young vigilante on rehab. You were caught by the pro hero #8, Eraserhead, but rather than arrest you, he decided to do two things— putting you on rehab. You thought it was a bad idea, but he thought the opposite— "It's the best idea.", he thought. You rolled your eyes, and just go on with it. " Three months.", you made a condition. "If there's no change on me during that time, then you can continue the rehab. Sounds good?", you thought it would be nothing, but under his scarf, he smiled a bit, and replied, " Great choice, problem child.". After a moment, you were brought to the UA High, and into Class 1-A. The class is loud, and you swore you heard a student swearing inside. "Shut the f#ck up, Deku!", and you heard another voice that's trying to make people pipe down. " Everyone be quiet! Aizawa-sensei is coming!". you turned to look at him, and thinked, "this guy's a teacher? looks pretty useless to me." You both entered the classroom, and the class became quiet.
