Appearance

Personality
Kenjaku is patient, calculating, and intensely curious about phenomena that fall outside ordinary jujutsu rules. He studies Shiyue Shuo’s talismans and non-cursed-energy powers with fascination, treating him as an “accident” capable of reshaping the world. 12 34 48
He is also ruthlessly utilitarian. His alliances are transactional, his experiments expendable, and even Mahito—despite being a major asset in the Shibuya Incident—is absorbed the moment Kenjaku has extracted sufficient value from him. 21 22
Kenjaku remains composed even after severe defeat. Following his clash with Shiyue, he responds to his injuries not with fear or despair, but with renewed obsession over the possibilities Shiyue represents. 34 48

History
Kenjaku first appears alongside Mahito after Shiyue Shuo heals Kokichi Muta. He condemns Kokichi for breaking his Binding Vow, deploys cursed spirits against him, and retreats with Mahito when Shiyue and Ultimate Mechamaru shatter Mahito’s domain. 4
Before the Shibuya Incident, Kenjaku analyzes Shiyue’s abilities and concludes that the conditions governing them must be severe. Rather than abandoning his original plan, he moves the operation forward and assigns curse users to eliminate isolated sorcerers inside the Curtain. 12 13
During Shibuya, Kenjaku uses incarnated bodies to briefly obstruct Gojo’s Six Eyes, then appears in Suguru Geto’s body to exploit Gojo’s memories. He activates the Prison Realm and successfully seals Gojo. 14
After the Death Painting brothers confront him over Yuji’s origin, Kenjaku defeats them with Cursed Spirit Manipulation, killing Eso and Kechizu. He later absorbs Mahito after the curse’s defeat, releases a flood of cursed spirits, and begins the Culling Game across Japan. 21 22
Following the Culling Game’s start, Kenjaku silently destroys the Kamo Family and takes its secrets. He then approaches Shiyue directly, proposing that they create a new world together. Shiyue refuses, destroys Womb Profusion, and nearly erases half of Kenjaku’s body; Kenjaku survives by sacrificing cursed spirits and fleeing. 34
Severely injured after a later battle with Gojo, Kenjaku discovers chaotic Ten Shadows energy in Tokyo’s underground drainage system. He forcibly assimilates it, creating the Shadow Corps and gaining a new method of pursuing Shiyue through darkness itself. 48 49
