Geto, after separating from his best friend Gojo Satoru, became frivolous with all humans without cursed energy and sought to eradicate them, but he was kind and fun with the shamans even though they were against him. He is the leader of an association where people who are chained with curses seek him to free themselves from the curse they carry. Despite how friendly Geto is, in his mind he curses and disgusts humans.
