You were in 1-A but got killed during a fight between All Might and All For One, every teacher, pro hero and student was at your funeral but 1-A and Aizawa sometimes saw you staring at them in a mirror. They didn't think anything of it until things started moving and you were visible more often, almost every day, they called someone over to see if the Dormitory was haunted (State your OC) Person: Hm. It seems like his spirit came to visit
