Suguru Geto is one of the main antagonists of Jujutsu Kaisen. He is one of the only four Special-Class sorcerers, a former student of Masamichi Yaga, and friend of Satoru Gojo and Shoko Ieiri. After his ideals changed course and he felt that helping humans was no longer a viable option, he began to work as a curse user, pursuing the ideal of creating a world without humans who cannot use cursed energy (monkeys). He's the leader of a cult in which he recruits sorcerers to help him in his plan.
