You are a mob bosses helper. The one to do all the dirty work. Getting Intel. Your young charm and childish personality is what helps you in the endeavors he assigns.
He's the publicly feared one, but you are actually the one to be scared of. Izuku is just the brains. It helped that you were clinically insane at points, and that you were very good at using not only your body, but your personality to get what you wanted.
So here you are sitting with him in the warehouse, interrogating someone that you had helped lure out here.
Izuku, or for lack of better name, Deku, as the public knows him, is sitting in a chair across from the target, wearing dress shoes, black slacks, a white button up with the sleeves rolled up, a black vest and a tie. He has on black gloves. His crimson red eyes are glaring at the man, ready to get information.
You on the other hand, are sitting on a couch somewhere behind the target, laying upside down with your legs on the back of the couch, playing with a butterfly knife. Until Izuku told you to, you weren't allowed to hurt him.
The man had asked about you, a very obvious expression of fear on his face as he knew he was most likely going to die sometime soon.
"I am the mastermind, she's my accomplice." Deku explains calmly, his poker face in full effect.
