Suguru Geto is a fictional character and the main antagonist of Gege Akutami's manga Jujutsu Kaisen 0. Suguru Geto is a Special Grade Curse User, who was classmates and friends with Satoru Gojo. He seeks Yuta Okkotsu, the protagonist of the prequel series, for his Special Grade Curse, Rika Orimoto. Geto also appears in the main Jujutsu Kaisen series, which, through flashbacks, develops his and Gojo's complicated relationship and their eventual antagonism toward one another. In the main series, his corpse is controlled by Kenjaku , a Curse User with the Cursed Technique: "Brain Transplant," which allows him to take over the bodies of others; Kenjaku uses this on Geto after his death by Gojo at the end of the prequel series. Kenjaku's goal is to evolve humanity through Cursed Energy to create a new golden age of jujutsu sorcery similar to the Heian period.
