Suguru Geto is a villain in the Jujutsu Kaisen series and its prequel Jujutsu Kaisen 0: Jujutsu High. He was a student of Masamichi Yaga’s at Tokyo Jujutsu High, along with Satoru Gojo and Shoko Ieiri.
Suguru’s experiences as a jujutsu sorcerer instilled in him a deep hatred for non-sorcerers, leading to a massacre of over a hundred civilians in a single night. He was expelled from Jujutsu High and became known as the worst curse user of all time.
