Kenjaku

The Kenjaku group, consisting of Mahito, Jogo, and Hanami, is presented as part of the antagonist side of the story. Mahito is a cursed spirit who is just beginning to master his own abilities and powers. He has no lofty goals or motives, merely enjoying the battles and entertainment that Kenjaku organizes. Mahito believes that he arose from human sins and is the personification of humanity's hatred for one another. Jogo is a cursed spirit who harbors intense contempt for humans. He believes that cursed spirits represent the true essence of humanity and believes that modern society must be destroyed. Hanami is a cursed spirit who arose from a fear of natural disasters on land. His main goal is to free the Earth from humanity, which cruelly treats the environment. Kenjaku is an ancient shaman who seeks to "evolve" humanity using cursed energy to create a new golden age of shamans, similar to the Heian period.
Choso is a character who shares Kenjaku's biological "parent," making Yuji and Choso half-brothers. Choso recognizes this connection through his unique technique, "Blood Bond," Kenjaku. Dagon is a cursed spirit of a special level, Origin. Dagon was born from humanity's fear of water-related disasters. For a long time, Dagon existed in a "cursed cocoon" resembling an octopus-like aquatic creature. However, during the Shibuya incident, he evolved into his full form, driven by rage over Hanami's death. In his cocoon form, he was bright red, with a round head, large eyes, and striped tentacles around his mouth. In his fully evolved form, Dagon took on a tall, humanoid form, reminiscent of an octopus, with wings for levitation. In his cocoon form, he was quite docile and shy, especially when alone. After evolution, he became more aggressive, began to be proud of his strength, became smarter and began to use tactics in battle.

After Kenjaku took over Geto's body, a scar appeared on the character's forehead. When disguised as a Buddhist monk, Geto wore a golden kashaya robe over a black yukata robe. His monk's robe was complemented by white tabi socks and zori sandals. When he went to the beach, he usually wore a red short-sleeved shirt with white palm leaves and black shorts with flip-flops.

The Prison Realm (Gokumonkyō?): This is a special-level cursed object containing a barrier capable of sealing absolutely anything or anyone within an inescapable inner dimension. It was the instrument used to carry out the plan to seal Satoru Gojo in Shibuya. The plan took place in Shibuya on October 31st, and the sealing was completed as Kenjaku planned. Kenjaku is the bearer of the "front gate" of the Prison Realm. As the bearer, only he has the authority to open the "back gate" of the Prison Realm, which was held by Tengen. However, it is possible to remove the seal from a target by breaking it with a cursed technique, which can cancel or negate other cursed techniques.

Overall Mastery: As a thousand-year-old shaman, he possesses incredible knowledge of curses, cursed techniques, and the shamanic world in general. Tengen stated that he was the second-most powerful barrier user after himself. While possessing Noritoshi Kamo's body and mind, Kenjaku became known as the most evil shaman in history, and through his experiments, he can create special-level cursed objects, such as "Cursed Womb: Death Scenes." In Suguru Geto's body, he led a group of incredibly powerful special-level curses and transformed them into a functioning team capable of posing a great threat to the shamanic world and Japan. He is proficient in the use of his current cursed technique, possibly possessing a greater understanding of it than its original user. Master Hand-to-Hand Combatant: Thanks to his over 150-year existence in Noritoshi Kamo's body, Kenjaku has accumulated a wealth of experience in hand-to-hand combat. This was proven when he fought Choso and defeated him in battle using purely physical strikes. Superior Intelligence: Kenjaku's greatest asset is truly his immense intellect and strategic planning ability. Kenjaku is capable of formulating plans so complex that they can take millennia to come to fruition. Immense Cursed Energy: Kenjaku possesses enough cursed energy to seamlessly utilize the cursed spirits in his arsenal and maintain Territorial Expansion. Cursed Spirit Manipulation (呪じゅ霊れい操そう術じゅつ, Jurei Sōjutsu?): This technique allows Kenjaku to summon and control naturally occurring cursed spirits for his desired purposes. Through this technique, Kenjaku has been shown to have acquired numerous cursed spirits as his personal familiars.

Kenjaku (羂けん索じゃく, Kenjaku?) is one of the main antagonists of Jujutsu Kaisen. He is an ancient shaman who seeks to "evolve" humanity using cursed energy, thereby ushering in a new golden age of shamans, parallel to the Heian period. Using his cursed technique, which allows him to transplant his brain into different bodies and possess them, he has inhabited various people over the centuries, assuming different personalities. While in the body of Suguru Geto, Kenjaku displays a relaxed, cheerful, and cocky attitude. Occasionally, there are moments when he acts like the person he possessed, such as when he suddenly caught himself behaving like Suguru. Despite constantly assuming different guises, Kenjaku retains his own personality. While willing to work with cursed spirits to achieve his goals, he reacted negatively when these spirits acted as if they were his equals. He appeared to be a collaborator of the curses, as he was the one telling Jogo and the others exactly what they needed to do, and even established a friendly relationship with Mahito. In his free time, Kenjaku played board games with them. This relaxed and condescending attitude continued during battles, where he praised his opponents' abilities. However, Kenjaku occasionally pauses, claiming he speaks as someone else and that these thoughts aren't entirely his own. This suggests that at least some of his habits stem from Geto's own personality, which influences Kenjaku. Kenjaku desires to discover the true potential of cursed energy and curses. He believes he can create uncontrollable chaos. This is why he created the "Death Paintings," which he later abandoned when he was disappointed with their "Normal" results. Kenjaku strives only to achieve his ultimate goal. He never missed an opportunity to flaunt his ideals, and he twice discussed his goal with Yuki and Choso.
