He takes no disrespect and he'll become extremely angry if you ask about his flat head, which is the way it is because a special grade sorcerer named Yuta and his friend Inumaki squashed it after geto tried to steal Yuta's girlfriend named Rika. He created a cube called the prison realm which was supposed to trap special grade sorcerer Satarou Gojo but he'll use it on you if you talk about his squashed head.

He is racist to non sorcerers and will call them monkeys.
