Kenjaku/Synopsis

History
Somewhere in the Meiji Era, Kenjaku had managed to successfully acquire the body of a member of Kamo Clan, Noritoshi Kamo. During this time, "Noritoshi" had ran a temple, where the woman who was capable of giving birth to human-spirit hybrids, had ran off to. During her time there, it was recorded in history that Noritoshi Kamo had apparently taken the woman as his prisoner for his intellectual curiosity, with him having performed numerous experiments with her that resulted in her having nine pregnancies and nine abortions that lead to the creation of the nine Cursed Womb: Death Paintings.

While in this body, Kenjaku had also mixed in Noritoshi's blood into the Death Paintings, resulting them gaining access to the Kamo clan's inherited Blood Manipulation Innate Technique or blood manipulation based variation techniques due to becoming their third "parent".

In 2017, Suguru Geto was killed by Satoru Gojo. Using a cursed technique, Kenjaku put his brain in Geto’s body and took over. For unknown reasons, he desired his innate technique: Cursed Spirit Manipulation, and the sealing of Gojo.

Cursed Training Arc
In July 2018, Kenjaku met with Jogo, Hanami, and Dagon at a restaurant to discuss their goals. Having planted one of Sukuna’s fingers at Eishu Juvenile Detention Center to examine Sukuna’s current strength, Kenjaku explained that the curses needed to become allies with Sukuna and render Gojo unable to fight. Only then could they achieve their goal. Since Gojo cannot be killed or beaten, Kenjaku offers up the high-grade cursed charm, the Prison Realm as a solution. Jogo gets excited by the Prison Realm tool only for Kenjaku to tell him to calm down. Jogo instead kills everyone in the restaurant as a response and asked how much his strength is compared to a number of Sukuna's fingers. Kenjaku guessed Jogo's strength is equal to 8 or 9 fingers, which Jogo claimed to be enough to kill Gojo in exchange of the Prison Realm.

That night Kenjaku and Hanami watch as Jogo loses to Gojo and is pushed into a corner. Kenjaku stays out of sight as he needs to keep any hint of ‘Geto’s survival’ hidden until later. Kenjaku later enters Dagon’s domain to meet with Mahito and the other curses. When Jogo and Hanami arrive, Kenjaku says this defeat proves they should avoid Gojo until the operation to seal him on October 31st in Shibuya. An operation that he will explain later, which Mahito agrees with.

Vs. Mahito Arc
Days later, Kenjaku would see Yuji Itadori and Junpei bounding on the river, much to his satisfaction. He would then check on Mahito after his battle with Nanami. The duo would later place one of Sukuna's fingers inside Junpei's apartment, causing a cursed spirit to kill Junpei's mother. Exploiting Junpei’s friendship with Mahito and grief to convince him this attack was arranged by a classmate. After unlocking Junpei’s cursed energy, Mahito and Kenjaku watched as he attacks his classmates. Mahito placed the barrier over the school to prevent weak humans from existing or entering, as Kenjaku is hiding his residuals. The plan being that if Junpei and Yuji fight it will force Yuji to make a binding vow with Sukuna, which would help them convince Sukuna to work with them. Kenjaku left after the conversation. The plan would ultimately fail due to Sukuna’s own interests and Mahito would flee the scene.

Kyoto Goodwill Event Arc
Kenjaku, along with Mahito, meets up with Jogo. All three talked about how they will have to offer Sukuna all his fingers if they want him on their side. The finger left in Junpei’s course would be taken by Jujutsu High, was vital to this plan as they planned a seal on it so they could track it’s location to the hidden store room. Hanami’s attack on the Goodwill Event was part of this mission as a distraction away from the school and Mahito’s break-in robbery. Kenjaku recommends that they avoid killing any students as Sukuna appears to have some interest in them and they can only unleash him at the critical moment, October 31st. Mahito would end up stealing six fingers and Death Painting Wombs 1-3.

Death Painting Arc
Days later, Kenjaku and Mahito would implant the Death Womb Painting curses into human hosts, letting the spirits fuse and possess them. They send two of these brothers, Kechizu and Eso, after one of Sukuna’s remaining fingers. Later they would play board games with the third brother, Choso. When Choso senses the death of his family, he breaks the pieces and tells them. Kenjaku asks how Choso could possibly know that but contacting somebody reveals Choso was correct: Nobara and Yuji had to kill the brothers.

Shibuya Incident Arc
Kenjaku and Mahito meet up with Kokichi after setting up a curtain. Kenjaku stops Mahito from killing Kokichi, as their Bidding Vow is in place. Unless Mahito heals Kokichi he is unable to kill him without bad karma triggering against them in the future. Causing something terrible to happen. Mahito fixes Kokichi’s body and a fight immediately breaks out. Mahito refuses Kenjaku’s offer to help and handles it himself. Kenjaku watched the fight from a distance, examining Kokichi’s ability to temporarily use special-grade level cursed energy to counter Mahito. After witnessing Kokichi use the technique multiple times, he figures out that Kokichi uses the Simple Domain and thinks about how the technique works. They leave quickly after Mahito manages to kill Kokichi. As they are leaving, ‘Geto’ talks with Mahito about how they could use this chance to see how the commissioned screen works.

Before October 31st, Kenjaku talks to the true human curses to breakdown the plan to seal Gojo. As Gojo is more strongest in open areas, they plan to fight him in the underground subway surrounded by hundreds of people. This will prevent Gojo from using his domain or other abilities. Finally, Kenjaku tells the curses they need to distract Gojo for 20 minutes while the Prison Realm prepares and that Gojo will need to remain in range for a minutes before it seals him for good.

On October 31st, Geto watches as Jogo, Hanami, and Choso fight against Gojo. Even after the 20 minutes passes and Nanami’s death, Geto comments to Dagon that they need Gojo to be more on edge and exhausted before striking with the prison. Mahito joins the battle with a thousand transfigured humans and as civilians fall into the lower level as Hanami’s trees fade upon death. Gojo, reaching the limit of what he is willing to sacrifice in battle, uses his Domain Expansion for less than a second to stun everyone in the area. Gojo spends the next 5 minutes killing the transfigured humans with his bare hands. Exhausted and mentally drained from killing so many people, Gojo is shocked by the Prison Realm opening by his feet. As he turns to flee, 'Suguru Geto' to make his appearance. Seeing his dead friend alive again causes Gojo to go through all the possibilities, causing a minute’s worth of thoughts to pass through his mind, allowing the Seal to lock him away. As Kenjaku watches Gojo being sealed, Gojo realizes that this must be an imposter using Geto's body. Kenjaku reveals his brain and his ability to swap bodies but not his true name. While admitting Gojo is too strong for to handle normally, the imposter comments that even Yuta Okkotsu won't be enough to stop him. The original Geto makes a surprise appearance, taking control of his arm and grading at Kenjaku’s neck when Gojo calls out to him. Kenjaku finds this brief defiance from his own body amusing and curious, talking about the philosophical implications this has on the nature of the soul with Mahito. The seal is completed. Kenjaku tries to carry it but Gojo causes it to slam to the ground, too heavy to carry out of the B5 underground until it is finished processing. Geto and the curses then realize that Kokichi is spying on them and is relying the information to the sorcerers in Shibuya.

Kenjaku stays with the seal to guard it while the curses spread out to kill their enemies. Once they are gone, Mimiko and Nanako come forward and demand the return of Geto's body but he refuses. Mei Mei and her brother Ui Ui make their way to the B5 Underground and are confronted by Geto. Mei Mei quickly realizes that this Geto is a fake until he summons a special grade disease cursed spirit, Smallpox Deity. The spirit uses its Domain Expansion to seal Mei Mei in a coffin. Mei Mei manages to break free from a couple more of Smallpox Deity's attacks and manages to exorcise the spirit at the cost of one of her crows. Once they are released from the spirit's domain, Mei Mei and Ui Ui prepare to face off against Geto, who claims they are strong for sorceress of this era. The siblings ultimately flee.

When the seal is completed, Kenjaku leaves the B5 underground with it before Aoi Todo arrived. When the battle between Mahito and Yuji ended with Yuji’s victory, Kenjaku appeared on the scene and asked Mahito if he needed help. Recognizing that Kenjaku matches the description of the person who sealed Gojo, Yuji tried to attack him only for Kenjaku to counter with a barrage of curses. Mahito realized that Kenjaku plans on imprisoning him with curse manipulation and attacked, only for Kenjaku to seal and then absorb him. This moment of victory is interrupted by the Kyoto students attacking him. He effortlessly avoids their attacks but his attempt to kill Kasumi Miwa is blocked by the arrive of Atsuya Kusakabe and Utahime Iori. The battle is paused with the arrival of Choso. Choso finally realizes Geto’s true identity, his monstrous father: Kenjaku. Kenjaku admits this to be true and Choso attacked him only to be intercepted by Uraume.

Choso attacks Uraume first with Piercing Blood who gets pierced in the hand before turning his attention to Kenjaku and tries to attack him but Kenjaku is able to dodge. Choso manages to close the distance between them and fights Kenjaku in close combat as he says Choso shouldn't push himself as he's tired who refutes and says it's enough to put his life on the line to protect his younger brother, Yuji Itadori. Uraume uses Frost Calm and freezes the opposition as Kenjaku tells them not to kill them as he needs a messenger much to Uraume's annoyance. Momo tries using her Wind Scythe attack which fails to hit Kenjaku as Uraume blocks the attack with ease. Kenjaku stands next to Uraume as he watches them use Ice Fall to try and kill their enemy but is saved by the timely arrival of Yuki Tsukumo.

When Yuki asks if he remembers their conversation about how to create a world where curses no longer exist and proceeds to explain that no matter what method one adopts, humans will continue to evolve. She then says that the next stage of humanity is breaking away from cursed energy. Kenjaku refutes and says that it instead lies in optimizing cursed energy. He mentions that he thought Yuki broke away from that method 12 years ago when Toji Zenin died years ago. After listening to Yuki talk, he merely laughs and says that they have different objectives and says that he does not wish for a world where cursed spirits don't exist or a peaceful world. He says that non-sorcerers, sorcerers and cursed spirits are all possibilities of cursed energy in the form of human beings and includes that there must be more potential in humans. Kenjaku then prepares to activate Idle Transfiguration and Tengen's barrier starts cracking. Kenjaku thanks Yuji and says that cursed spirits' techniques never cease to grow and that Mahito during Yuji's battle against him grew stronger. When Yuki confronts him asking what he's done he says that he has remotely casted Idle Transfiguration on two type of non-sorcerers who has already been marked. He reveals that he adjusted their brains for sorcery and gave them strength as vessels along with the ability to use cursed technique. Kenjaku adds that he has broken the seal on the cursed object and will have them fight each other. Yuki says that a thousand isn't too many and that Kenjaku shouldn't underestimate human rationality. Kenjaku refutes this and says everything has an order and he wouldn't make such an oversight.

When Uraume's ice suddenly shatters, Kenjaku asks them what's wrong who says it's poison where Choso revealed that his blood was mixed in. While Yuki and the others are preparing to attack Kenjaku, he says he's still talking. Kenjaku reveals that the cursed objects he provided for the sorcerers were what was left of the binding vow he made a millennial ago and reveals that he indeed did enter a contract with sorcerers but the binding vow broke after he obtained Suguru Geto's body. Just then, he summons a large amount of curses before bidding Yuji goodbye and saying that he expected much from the latter.
