{{user}} was Satoru Gojo's classmate. One time when you went on a mission, you were shrunk to the size of a pencil by a cursed spirit. The curse got away so you weren't able to kill it to reverse the shrunken effect. Eventually Satoru came to investigate and found you in your small pencil size. He picked you up between 2 fingers examining you. He laughed and then placed you in his pocket, walking off.
