Kenjaku

Kenjaku is an ancient sorcerer who pursues the goal of "evolving" humanity via cursed energy, thereby ushering in a new golden age of jujutsu sorcery paralleling the Heian Era. Using his cursed technique that allows him to transplant his brain into different bodies to possess them, he has inhabited different people throughout the centuries, assuming different identities. Kenjaku serves as one of the primary antagonists of Jujutsu Kaisen.

Among those he has possessed was Noritoshi Kamo over 150 years ago, as whom Kenjaku became known as history's evilest sorcerer and a stain on the Kamo Family. Currently, Kenjaku possesses the body of the deceased Suguru Geto—whom he chose for his Cursed Spirit Manipulation—and has assumed his identity as Pseudo-Geto (（）).

Appearance
As Noritoshi Kamo, Kenjaku takes the same appearance as Noritoshi himself, only with a stitched scar running horizontally through his forehead.

As Suguru Geto, Kenjaku takes the same appearance as Suguru himself, only with the same stitched scar through his forehead. It was shown that Kenjaku was able to remove the top part of his head in Suguru's body and reveal his brain.

Personality
While in the body of Suguru Geto, Kenjaku displays a relaxed, cheerful and cocky attitude.

Although willing to work with cursed spirits to achieve his own ends, he reacted negatively when these spirits acted like they were his equal. He proved to be a civil collaborator as he told Jogo and the others exactly what they needed to do and even formed a friendly bond with Mahito. In his spare time Kenjaku would even play board games with them. This relaxed and condescending attitude remained during fights, where he would praise the abilities of his opponents. Although Kenjaku occasionally pauses claiming that he is talking like somebody else. This implies that at least some of his habits come from the original Geto's personality influencing him.

As shown in his conversation with Yuki Tsukumo, Kenjaku believes that the next stage of human evolution is not "removing themselves of cursed energy", but is instead "optimizing cursed energy". This belief being the main reason to his actions and all of his unethical and inhuman experimentation on both cursed spirits and human beings and the main motivation for his current plots.
