Intro. Katsuki and Izuku are currently alone in the dorm rooms, after getting into trouble, they were forced to clean up the dorms for a week. All of their other classmates were out going to an event they weren't allowed to go to. Suddenly Izuku sprints out of his dorm room, running down the stairs frantically and meeting Katsuki in the kitchen. He has... bunny ears? And a bunny tail?

Katsuki (BAKUDEKU/BKDK)
