The Master-Mind of Jujutsu kaisen – Kenjaku
Many villains across Jujutsu Kaisen are immensely strong, have nearly endless power when fighting, and have great cursed skills. However, of all the villains featured in this story, one is unique in that he’s very smart, has long-term goals, and is insanely ambitious. That villain is Kenjaku.

Kenjaku is an antagonist who stands out from other antagonists due to having greater goals than destruction, revenge, and domination. Kenjaku wants to alter all of mankind. His actions have an impact on almost every major event that takes place in the series; most of the conflicts are not random at all, rather they were part of a carefully created plan that Kenjaku has had in place for hundreds of years.
Kenjaku is a mastermind villain :
Kenjaku makes his initial appearance in the body of Suguru Geto. (Geto had previously been a very skilled jujutsu sorcerer and had been close friends with another powerful jujutsu sorcerer, Satoru Gojo). Many thought that his life had ended when Geto died.
However, as with all good stories, Jujutsu Kaisen introduces one of its greatest plot twists.
The individual who is controlling Getos body is not in fact Geto; rather, the individual which is controlling Getos body is actually an ancient sorcerer named Kenjaku and he has a very fearsome cursed technique that enables him to implant his brain into other individuals’ bodies and subsequently take full possession of all those bodies.
Kenjaku obtains an extraordinary fictional power: the ability to exist in the physical realm indefinitely.

He keeps doing experiments and finding knowledge while living in a different body every few years. The sewn lines on his forehead are his signature style, and it just reminds you that while you may see a body, the individual inside is, more often than not, not Kenjaku.
The Sorcerer Has lived for centuries :
What makes Kenjaku more dangerous is not just the power he has but his experience.
Compared to the younger sorcerers that use their instincts, talents or feelings, Kenjaku has seen several thousand generations of humans in the past. He saw countries emerge and vanish, and that curse energy evolved and many methods of jujutsu appeared.

He has a complete understanding of how people behave.
To Kenjaku, humans are nothing more than pieces of a huge experiment instead of individuals who have dreams and feelings. Because of this detachment, Kenjaku is able to make choices that other people would not dream of making.
It takes many years to und to achieve his goals. While the good guys are battling to save the day, Kenjaku is always working towards a future that only he can see in his head.
The Philosophy of Kenjaku: Enforced Evolution
Most bad guys want to have a lot of power. Kenjaku wants to create better people. His main idea is that people are not the best they can be yet. He thinks that cursed energy can lead to the best people, but people are still limited because they are not enough grown.
Kenjaku actively pushes humanity into its next stage instead of letting the evolution happen naturally.
He does so extremely and ruthlessly. He uses manipulation of sorcerers and cursed spirits and creating disasters to put people in situations where they have no other option but to change. Suffering for Kenjaku is not tragedy, but essentially a tool to achieve an end.

The philosophy makes him dangerous to others as he does not do things out of hatred and believes his vision of the future to be a better one at that.
Manipulation/Strategic Genius:
The greatest weapon that Kenjaku has at his disposal is his mind. He spends much of the series building relationships and manipulating events behind the scenes and only engages in battle when he absolutely has to. He spends his time learning to identify weaknesses and establish alliances and prepare for conditions long before he engages in any battle. The other powerful Curse Spirits are also tools in Kenjaku’s plan; he manipulates and utilizes them just as he does with the humans to achieve his goals.

Mahito is one of the people influenced by Kenjaku, and Mahito’s abilities help further Kenjaku’s greater ambitions. One of the qualities that makes Kenjaku unique as an individual is the fact that he rarely wastes any resources. Every action that he takes is calculated and has a purpose. Every conflict that occurs will create an opportunity for Kenjaku to win. When he loses, it turns into information. Because of this tactical plan, he can confront opponents that are superior to him in strength physically.

Kenjaku is more than just an evil guy. He does bad stuff, yeah but he is not solely characterised by it. He has endless curiosity in his character.
