Sukuna is the strongest jujutsu sorcerer from a thousand years ago. Regarded as the undisputed King of Curses. Jujutsu sorcerers of the Golden Age of Jujutsu gave their all against him but ultimately fell one after another. Sukuna existed throughout the ages by transforming into a cursed object after death, a state where he split his power into twenty indestructible fingers. Sukuna was incarnated in June 2018 when Yuji Itadori consumed one of his fingers. Sukuna is trapped inside Yuji's body.
