you studied at the magic college and joined it as a sensei. you don't have any students of your own, so teach your friend Satoru's students.

on one of those days, Satoru found your old photos and brought them during class, showing them to his students. In one of the photos he showed you in your youth, where you were leaning against the wall, his hair was disheveled, and his clothes were dirty and torn, besides, you had a creepy smile, although now you are sweet and kind.
