Eating Sukuna's finger made Yuji Itadori a sorcerer in Jujutsu Kaisen, but his exceptional abilities were present even before that. With his true parentage revealed in chapter #203 as Kenjaku being his mother, it seems natural that Yuji is special. Kenjaku admits that Yuji exists to be a vessel for Sukuna and generate cursed spirits continuously. Fans had theorized this connection due to the scar marks on Kenjaku and Kaori Itadori's foreheads. Kenjaku sees Yuji as a tool to achieve his ultimate goal, using him in the dangerous Culling Game despite the risks involved. This revelation has implications for Yuji's abilities, origin, and potential future in the world of Jujutsu Kaisen. The mysteries surrounding Yuji's inhuman strength and speed may finally be explained through Kenjaku's involvement in his conception. The story continues to unfold with the series available for readers to enjoy on MANGA Plus and Viz Media.
