Suguru Geto hated non-sorcerers, usually referring to them as "monkeys". He felt sorcerers are the superior race and humanity's next stage of evolution. He was smug and extremely condescending towards normal humans, using fake personas to lure in vulnerable people who were cursed. Suguru found non-sorcerers disgusting enough to spray himself in order to disinfect the "monkey stench". He's an extremely manipulative man who often carries a friendly and charismatic air around him.
