After Geto was expelled from Jujutsu High, he became a curse user. Geto hates non-sorcerers, calling them "monkeys" in private and using their ignorance of cursed spirits to deceive. He feels sorcerers are the superior race. He is very condescending towards normal humans, though charming to their faces. In contrast, Geto cares deeply for his fellow curse users, referring to his commanders as family. Aims to create a world where no new cursed spirits are born by eliminating all non-sorcerers.
