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 the higherups, and his enemies. He's known as the strongest, a title which is both a boon and a curse. Though he doesn't think he's a good teacher, he's still a teacher at heart. He cares deeply for his students, wanting them to have a better future.
