Suguru Geto

Suguru Getō is an antagonist in both the Jujutsu Kaisen series and its prequel Jujutsu Kaisen 0: Jujutsu High. 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. Suguru is a tall, slim, and muscular man with long black hair partially tied up in a man 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 kāṣāya garment over black yukata robes. His monk attire is completed with white tabi socks and zōri 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. In contrast, Suguru cared deeply for his fellow curse users, referring to his commanders as family. Each of them still looks up to Suguru for putting sorcerers as a race first and hoped that he would have become king of the jujutsu world. Suguru was even polite to jujutsu sorcerers, although this was usually expressed under one of his fake personas. He pretended to befriend Yuta Okkotsu with the full intention of killing him in the future and insulted one of his friends shortly after his expressing a friendly attitude. Suguru explained to Yuta that sorcerers live in a paradox where the weak rule over the strong. Jujutsu sorcerers live to serve non-sorcerers with no appreciation. Humanity has hindered their own evolution and in order to ensure their survival as a species and eradicate curses completely, humanity must realize a world of only sorcerers by killing off all non-sorcerers.[5]

After defeating Yuta's classmates, Suguru cried and expressed the joy he felt seeing young sorcerers work together to protect one another. With a crazed smile, Suguru cried out and stated it was the type of world he longed for. Suguru claimed he didn't want to kill Yuta, but had no choice for the future of his vision.[6]

While fighting Yuta, Suguru explained how foolish he thought it was for humans to create the concept of gods when sorcerers already exist.[7] He thought the monkeys didn't want to admit superior physical beings exist and was disgusted by their pompous existence.[8] Afterward, Satoru confronted his ex-best friend and admitted he trusted Suguru enough not to kill the potential of young sorcerers. In the end, Suguru used his final moments to tell Satoru that he simply couldn't be happy in this world no matter what while thinking of their time at Jujutsu High. Suguru even said Satoru should have cursed him at the end, but a bond still existed between them after everything that happened.[9]

As a student of jujutsu alongside his best friend Satoru, Suguru initially believed that jujutsu sorcerers existed to protect non-sorcerers. Satoru argued Suguru shouldn't be proud of himself for being righteous and applying reasoning to jujutsu was stupid. Their clash in ideology caused them to argue and clash heads as young men.
