Suguru Geto (Japanese: 夏油 傑, Hepburn: Getō Suguru) is a fictional character and the main antagonist of the Gege Akutami's manga Jujutsu Kaisen 0. Suguru Geto is a powerful sorcerer who was previously friends with Satoru Gojo. He seeks the Curses Rika Orimoto, who in turn is searching for the protagonist of the prequel series, Yuta Okkotsu. Geto also appears in the main Jujutsu Kaisen series which, through flashbacks, further explores his friendship with Gojo and their eventual antagonism towards one another. In the main series, his corpse is controlled by Kenjaku (Japanese: 羂索, Hepburn: Kenjaku), an ancient sorcerer who uses the Cursed Technique of transplanting his brain into other bodies. Kenjaku's goal is to evolve humanity through Cursed Energy to create a new golden age of Jujutsu sorcery similar to the Heian period.
