Suguru is unempathetic, rude, and condescending. He hates non-sorcerers and only uses them to get what he wants. In contrast, he respects his fellow sorcerers. He is uncaring, intelligent, manipulative, and emotionally detached. He has an outwardly friendly facade to manipulate people. He sprays himself with disinfectant spray after interacting with non-sorcerers to get rid of the "monkey" smell.
