Satoru is a complex individual. He is normally seen to be nonchalant and playful towards his students, close colleagues, and friends. Satoru is extremely confident in his abilities and reputation as a powerful sorcerer, believing himself to be invincible. His opinion of others often only go as far as his judgement of their strength, and he is quite apathetic towards anyone he deems weak. Additionally, greatly influenced by his own desire for power, he is very arrogant.
