Kenjaku

It is unknown what Kenjaku's original body looked like. He can only be distinguished by the stitches and scars that circle the top of his vessel's head. These are from the procedure required to transfer Kenjaku's brain, his only personal feature, into his host. Unlike a conventional brain, Kenjaku's has teeth.

In Suguru Geto's body, Kenjaku looks exactly as Suguru did during the Night Parade of a Hundred Demons, the day of his death.

Kenjaku is someone who has existed under countless identities for over a thousand years. There are even moments where he acts like whomever he's possessing unintentionally, such as when he caught himself suddenly acting like Suguru.[4] Despite constantly assuming different identities, Kenjaku retains a strong core personality. He is calm and calculating, rarely displaying signs of panic or distress and often has entire scenarios planned out in advance. At times he can appear cheerful, playful, and even charming, but he is a manipulative, and deeply egotistical individual who will stop at nothing to further his ambitions regardless of who he harms.

While Kenjaku is uncaring and aloof when it comes to things that disinterest him, he's very talkative when it comes to himself or his interests. Kenjaku has a habit of going on long monologues and enjoys drawing out small talk with anyone, even his enemies. This can vary from casually educating someone on the state of the world or ruthlessly taunting his opponents. Kenjaku's demeanor is often optimistic and outspoken, but it carries an aura of condescension, which often infuriates those he is talking to, even his allies. Uraume in particular finds Kenjaku annoying and doesn't enjoy his company at all despite them being longtime comrades.[5][6][7] Kenjaku is unapologetically arrogant because he possesses skills that back it up. This empowers him to carry his aura of superiority into dangerous situations. He will attack and severely injure someone all while casually explaining his ideals, goals, or abilities as if he's educating them. Even when faced with Satoru Gojo, Kenjaku made jokes and casually taunted him as if Satoru didn't confront him with the intent to kill.[8]

Kenjaku doesn't intentionally intimidate anyone or control people through fear to get them to serve his interests. He manipulates them in clever ways using his charm to convince them they share a common goal. The mighty Sukuna, the calamity of aggression that disregards all else, worked with Kenjaku to split his soul into twenty cursed objects after death. Sukuna even protected Kenjaku from Satoru Gojo and agreed not to fight him before their agreement was concluded.[9][10] While Kenjaku's manipulative tactics don't rely on fear-mongering, they don't rely on loyalty or respectful leadership either. Kenjaku simply knows how to play people and use their desires for his own ends. Kenjaku convinced hundreds of sorcerers over hundreds of years to join the Culling Game as a second chance at life, a situation they could thrive in as blood-thirsty warriors.[11][12][13] Several curse users in Shibuya worked with Kenjaku in order to rid themselves of Satoru Gojo.[14] In the case where an entity Kenjaku wants to use doesn't share an enemy or an objective, he will fabricate one. He went to a foreign power in the United States military and convinced them to invade Japan under the guise of abducting sorcerers to study cursed energy as a potentially sustainable resource. In reality, he tricked them into entering the Culling Game's colonies only to sacrifice their soldiers for his plan.[15]

Kenjaku worked with Mahito's group of cursed spirits to work with him toward a world ruled by curses. While this isn't exactly what Kenjaku desires, his own interests aligned with theirs at the time. He gave them advice, spent time playing games with them, and supported Mahito and the others. However, Kenjaku believes himself superior to cursed spirits and was completely indifferent to the demise of Mahito's group in Shibuya. His only regret was not being able to absorb Jogo before his death. Kenjaku only stopped Yuji from exorcising Mahito so that he could absorb him and even thanked him for drawing out Mahito's strength.[16][17]

Pseudo-Geto asks Yuji to discuss the future (Anime) "Let us discuss the future" — Kenjaku's tendency to hold a one-sided conversation.

Kenjaku's self-centered tendencies are driven by his boundless curiosity. Even after existing for hundreds of years, he's fascinated by the possibilities presented by cursed energy. He essentially wants to know the true potential of cursed energy in the form of a being and believes he can discover it by creating uncontrollable chaos. This is why he created the Death Womb Paintings only to discard them when he was disappointed with their "normal" outcome. He has no interest in anything unrelated to his ultimate goal and only looks to build toward his endgame. Never missing an opportunity to flaunt his ideals, Kenjaku discussed his goal with Yuki and Choso on two separate occasions. Kenjaku told Yuki Tsukumo that humanity's future lay in optimizing cursed energy and that, unlike Suguru Geto, he doesn't desire a world without cursed spirits.[18] He admitted to Choso that he plans on merging the citizens of Japan into one entity simply because it seems like fun. He compared it to being a toddler holding a crayon with a blank piece of paper. Kenjaku even admitted that if that entity ended up being a funny face, that would be hilarious to him.[19]

Choso tired of Kenjaku's scheme Kenjaku proudly admitting his chaotic schemes are all for his entertainment.

Tengen and Kenjaku used to be friends at some point but now Kenjaku considers the former a shut-in. He doesn't believe that's any way to exist and claims that he's truly lived by comparison. Having lived across a thousand years of conflicts and alliances, Kenjaku perceives the world as cursed one.[20] He has profound contempt for all modern social structures, people, and philosophies that favor passivity and maintaining the status quo. He feels as if Japanese people incorrectly believe their lives are stable when in reality they're always on the brink of ruin. He knows not everyone will risk their lives while others are willing to die at any time without any hope for the future. Kenjaku despises both sides, believing that everyone should know the feeling of approaching their ideals step by step.[21]
