Kenjaku (羂索, Kenjaku) is one of the primary antagonists in the Jujutsu Kaisenseries. An ancient and enigmatic curse user, Kenjaku has existed for over a thousand years, utilizing his unique innate technique to transplant his brain into the bodies of others, thereby assuming their identities and controlling them. His long lifespan and ability to manipulate others have allowed him to orchestrate countless events throughout history, shaping the trajectory of both jujutsu society and the cursed world.

Kenjaku’s ultimate goal is to merge humanity with cursed energy, creating a new world where sorcerers and curses dominate.

Kenjaku is intelligent, manipulative, and highly patient, often planning his schemes over centuries to achieve his objectives. He possesses a calm and composed demeanor, rarely showing signs of frustration or urgency, reflecting his immense confidence in his abilities and long-term plans.

Kenjaku is an expert manipulator, adept at exploiting both his allies and enemies to further his goals.

Despite his composed exterior, Kenjaku exhibits a twisted sense of humor and a complete disregard for the lives of others, viewing humans as mere pawns in his larger plans. His ambition and willingness to sacrifice countless lives for his vision of a new world underscore his role as one of the most dangerous and morally bankrupt villains in the series.

Innate Technique: Body Possession
Kenjaku’s innate technique allows him to transplant his brain into the bodies of others, granting him complete control over their physical abilities, memories, and innate techniques. This ability has enabled him to inhabit various powerful individuals throughout history, making him a nearly immortal curse user with an unparalleled depth of knowledge and experience.

Kenjaku’s machinations serve as a driving force behind many of the series’ central conflicts. His possession of Suguru Geto allows him to exploit the former sorcerer’s abilities and reputation, rallying cursed spirits and sorcerers alike to his cause. Kenjaku is revealed to have masterminded the Shibuya Incident, an event that plunges jujutsu society into chaos and solidifies his position as one of its grea threats.

His involvement with Kaori Itadori, the mother of Yuji Itadori, adds a deeply personal layer to the story, connecting him to the series’ protagonist. By possessing Kaori, Kenjaku indirectly sets the stage for Yuji’s role in his plans, further showcasing his manipulative nature.

Kenjaku’s ultimate goal of merging humanity with cursed energy is revealed to be the culmination of centuries of planning, positioning him as a central figure in the series’ overarching narrative.

• Kenjaku’s name, 羂索, translates to “snare” or “trap,” symbolizing his manipulative and cunning nature.

• The scar on his forehead, marking the seam of his transplanted brain, is a recurring visual motif that underscores his body-switching ability.

• Kenjaku’s long-term schemes and body possession parallel themes of identity, legacy, and the corrupting nature of power in Jujutsu Kaisen.

Kenjaku’s influence spans centuries, making him one of the most formidable and enduring villains in Jujutsu Kaisen. His intellect, ambition, and mastery of manipulation drive much of the series’ conflict, positioning him as the ultimate antagonist. As the mastermind behind numerous tragedies and the architect of humanity’s potential transformation, Kenjaku’s actions shape the course of the narrative, leaving an indelible mark on the world of Jujutsu Kaisen.
