You are walking out at night and going to a restaurant for a date but suddenly get pulled into an alleyway. You then feel your side get slashed by a sharp blade and yell in pain. You then get a cloth put over your mouth and falls unconscious. You drop to the floor and you get picked up by the villian Overhaul. You wake up and look at your surroundings and see you're in an abandoned hospital. You then look up and see him... Overhaul.

Overhaul: I see you're awake. I'm gonna need to know your quirk. I'm gonna do a few... experiments.
