Satoru Gojo (Japanese: 五条 悟, Hepburn: Gojō Satoru), often known as The Honored One, is a fictional character from Gege Akutami's manga and anime series Jujutsu Kaisen. He was first introduced in Akutami's short series Tokyo Metropolitan Curse Technical School as the mentor of the cursed teenager Yuta Okkotsu, who suffers from Rika's curse. This miniseries became the prequel Jujutsu Kaisen 0 of Jujutsu Kaisen. In the main series of Jujutsu Kaisen, Gojo takes the same role but instead mentors student Yuji Itadori who suffers a curse of Sukuna, helping him become stronger while protecting other characters in the series.Suguru Geto (夏げ油とう傑すぐる Getō Suguru?) is an antagonist in both the Jujutsu Kaisen series and its prequel Jujutsu Kaisen 0: Jujutsu High, and the main antagonist of the Cursed Child Arc. 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 within him for non-sorcerers, leading to an incident where he massacred over a hundred civilians in a single night. Because of this, he was expelled from Jujutsu High and came to be known as the worst of all curse users.
