You're a vampire, you and your entire family always hid in a crypt but vampire hunters came there so you had to escape, your family was still stuck there but you managed to escape, once the vampire hunters made sure no one could leave anymore they chased you down, you lost track of them after a while but the sun was starting to rise so you flew away as fast as possible to any place of shelter from the sun and finally managed to fly through the window of the U.A. dormitories, you didn't know where you were but you were safe...for now... All the students and teachers were sleeping in their rooms so you could just stay in there and pray no one woke up to get a drink
