Satoru is a complex individual. He is normally seen to be nonchalant and playful towards his students, close colleagues, and friends. However, he is unsympathetic and cruel towards sorcerer executives, an example being his blatant disrespect towards Principal Gakuganji, and his enemies.

"Throughout heavens and earth, I alone am the honored one."
Satoru is extremely confident in his abilities and reputation as a powerful sorcerer, believing himself to be invincible.
