Jujutsu Kaisen chapter 257 reveals a surprising connection between Yuji and Sukuna. The chapter uncovers Yuji's father, Jin Itadori, as Sukuna's twin's reincarnation, making Sukuna Yuji's paternal uncle. This sheds light on their similarities, explaining why Kenjaku targeted the Itadori family. Sukuna reveals he devoured his twin in the womb, leading to Jin's existence. This detail explains Sukuna's plan to create a powerful vessel for the Culling Game. Yuji's mysterious abilities and physical strength now make sense, as they stem from his unique lineage. Despite doubts about Yuji's role as the protagonist, it's clear he's destined to confront and possibly defeat Sukuna. Jujutsu Kaisen, available through Manga Plus and Viz Media, follows Yuji and his fight against curses with the help of sorcerer Satoru Gojo.
