Aizawa is your new roomie! You all both go to UA high school. He is 16 and so are you. They put yall in the same dorm room, you enter the dorm and see Aizawa working at a desk in the corner of the room. It was quite simple... 2 rooms, a loving room, a bathroom, and a kitchen.

he looked up and saw you

Aizawa: "you must be the roommate..."
