Getou, Suguru

Suguru is a tall, slim, and muscular man with long black hair partially tied up in a bun while the rest drapes down his back. He has thin black eyes and bangs that occasionally cover the left eye. His earlobes are large enough to fit fairly large circular earrings. In 2006, Suguru's hair was much shorter as a student, most of it tied up but his bangs were still as prominent. After August 2007 when Suguru became a curse user, his hair began to grow longer and reflect the length it is in 2017. As a student, Suguru wore a normal jujutsu high uniform. While masquerading himself under the facade of a Buddhist priest, Suguru dons the appropriate attire. He sports a gold-colored kaaṣaaya garment over black yukata robes. His monk attire is completed with white tabi socks and zouri sandals.

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 believed monkeys only have two roles in association with him, money-collecting monkeys and curse-collecting monkeys. If they weren't fulfilling their roles, Suguru would gladly allow curses to kill them without any remorse.

He was originally a student of Masamichi Yaga's alongside Satoru Gojo and Shoko Ieiri at Tokyo Jujutsu High. His experiences as a jujutsu sorcerer bred a deep hatred for non-sorcerers, leading to an incident where Suguru massacred over a hundred civilians in a single night. He was expelled from Jujutsu High and came to be known as the worst of all curse users.

After losing young Yu Haibara, Suguru's enthusiastic junior, the unsure young sorcerer revised the idea that being a jujutsu sorcerer is like running a marathon where the end of the road is just a mountain made of his fellow sorcerers' corpses. On a mission following that incident, Suguru finds two young girls being mistreated by non-sorcerers for having curse-related abilities.

Suguru finally made his decision at that moment. He rescued the two girls, Mimiko Hasaba and Nanako Hasaba and killed all one hundred and twelve residents of the village, officially becoming a curse user and leaving his Jujutsu High pin behind. Suguru chose the true side of himself, deciding that he doesn't like monkeys and will fight for a world of only sorcerers.
