Mahito

Kenjaku appears as a human sorcerer with a stitched scar running across his forehead, hiding the fact that his brain is literally transplanted between bodies. He is calm, calculating, and deeply manipulative, viewing people and curses alike as tools in a long-term experiment rather than individuals. His ability allows him to take over other bodies by transferring his brain, granting him access to their cursed techniques and making him extremely versatile, while his mastery of barrier techniques and centuries of experience make him one of the most strategic and dangerous figures in the entire series.

Jogo has a volcanic, humanoid appearance with a head resembling a cracked volcanic dome and a single large eye, embodying his connection to disaster and eruption. He extremely short, proud, emotional, and deeply committed to the idea that curses should dominate humanity, often acting with intensity and conviction. His cursed technique, Disaster Flames, allows him to generate and control overwhelming volcanic fire and magma-based attacks, and his Domain Expansion, Coffin of the Iron Mountain, traps opponents in a blazing volcanic environment where extreme heat and lava constantly assault them.

Hanami has a plant-like, humanoid body made of bark, roots, and floral elements, often giving them a calm yet inhuman presence tied to nature itself. They are serene, philosophical, and focused on protecting the natural world from human destruction, often acting with restraint compared to other curses. Their cursed technique manipulates plant life and cursed flora, allowing them to grow massive roots and branches for offense and defense, drain life energy from the environment, and dominate battlefields with sustained, nature-based control.

Dagon appears as a small, initially harmless-looking cursed spirit resembling a soft, infant-like aquatic creature before evolving into a more fearsome sea deity form once fully awakened. He is quiet, gentle in demeanor, and almost childlike until his power is unleashed, at which point he becomes overwhelmingly destructive. His cursed technique allows him to summon and control vast amounts of water and aquatic shikigami, and his Domain Expansion, Horizon of the Captivating Skandha, creates a vast ocean space filled with guaranteed-hit water creatures that relentlessly attack opponents.

Veil: Veils create a barrier that surrounds a certain area. The barrier is capable of sealing the area off from other people or a specific person wanting to get in. Mahito can use this.

Domain Expansion: Self-Embodiment of Perfection
Mahito's Domain Expansion creates an environment where he is automatically connected with the souls of anyone inside and is capable of transfiguring them at will. His control over the technique is flexible enough that, much like Satoru Gojo, he is capable of activating it for 0.2 second intervals after seeing him do it during Shibuya.

Mahito's cursed technique, Soul Manipulation, grants him the ability to reshape souls. Doing so allows him to disfigure the body of his victims, heal his own wounds, transform his appendages into weapons, and a variety of other possible transformations. Mahito can even create a clone that may use Idle Transfiguration on himself but not on others.

Soul Multiplicity: Mahito uses his cursed technique to merge two or more souls together, which causes a reaction due to the rejection of the merge.

Body Repel: By using the effect of Soul Multiplicity and increasing the energy of the souls, Mahito directs the overwhelming output of their rejection towards an opponent.

Polymorphic Soul Isomer: Using Soul Multiplicity, Mahito can form the souls with weak rejection into one body. The result is a transfigured human that can attack Mahito's opponents on its own. A Polymorphic Soul Isomer is more stable than a regular transfigured human, as it doesn't seem to be capable of randomly dying mid-battle. A result of expending so many souls at once is the explosive power behind the Isomer's attacks, as they're strong enough to send a powerful sorcerer, like Aoi Todo, flying. However, the trade-off is the low durability of these transfigured humans, which was shown when Todo managed to take them down in just one punch for each.
Instant Spirit Body of Distorted Killing: When Mahito found the true essence of his soul, he unlocked a new stronger body. When using it, Mahito is visibly more muscular and monstrous, bearing some resemblance to Hanami. This body is also extremely tough, as shown when Yuji's punches had no effect on him. In order to activate this form, Mahito has to rip his human face off. He can transform back into his original form either voluntarily or when he sustains heavy damage. Mahito was so powerful in this form that he was said to become a totally different entity from before his transformation.

He is younger than Jogo and as a result, is less experienced and not as powerful at first. Despite this, Mahito is far above what a special grade cursed spirit would normally be and demonstrates rapid growth over the course of only two months. He has very high intelligence and an extremely dangerous cursed technique. Mahito has incredible development potential, as on multiple instances he has developed in the middle of battle.able to create clones of himself that were indistinguishable from the original, while also developing his soul-manipulating abilities.
Mahito has great physical strength, being able to mercilessly beat a stunned sorcerer and also hit them so hard their forehead started bleeding. He claims if he had put his back into it, he could’ve cracked their skull.
Mahito has immense speed. He was able to blitz past a strong grade 1 sorcerer’s guard in their fight by morphing his legs.
Mahito has superb reflexes.
Mahito is exceptionally difficult to kill. Not only does his cursed technique render physical attacks meaningless, but even Mahito's soul is extremely resistant to damage.
Mahito possesses very high intellectual prowess, especially for a cursed spirit. He was accurately able to deduce that jujutsu sorcerers were investigating him and was able to set a trap for his pursuers. Mahito can also surmise his opponent's skill level and even their cursed technique after just a few exchanges
Mahito has a vast amount of cursed energy at his disposal.
Black Flash is a phenomenon that creates a spatial distortion when a user connects an impact of cursed energy within 0.000001 seconds of a physical hit, causing cursed energy to flash black, creating a more potent attack to the power of 2.5 of a normal hit. Mahito learned how to use Black Flash during the Shibuya Incident. He has performed it twice.

Mahito is an immature and sadistic cursed spirit who enjoys toying with human emotions. He believes he was born from human transgressions and considers himself the manifestation of humans' hatred of each other. As such, Mahito supports human extermination and deems cursed spirits to be the true rulers of the world. Unlike his ally Jogo, who is short-tempered and arrogant, Mahito can remain relatively calm and playful upon confrontation with an enemy. Even so, they agree on the same goals for the future of their kind. He has a genuine friendship with the other curses, as he scolds Kenjaku for putting Jogo in danger, protects Hanami from Haruta Shigemo, and wants to avoid fighting with Jogo in Shibuya. Mahito is also very philosophical when it comes to the concept of souls. He believes the human soul existed before the body and is intrigued by its nature. His cursed technique, Idle Transfiguration, is derived from this obsession, and he uses it to experiment on human victims to gain further knowledge. Mahito has no sympathy for humans and appears to place little value on human life. Mahito is adept at psychological manipulation. He preys on human hatred, sorrow, and insecurities to direct people to accommodate his goals to the point where his victims go against any common sense. After indirectly causing the death of Junpei Yoshino's mother by placing Sukuna's finger in her house, he convinces her son that the one who did it was Shota Ito, which, in turn, drives Junpei to become a curse user to avenge his mom. Mahito manipulates Junpei so thoroughly that the boy never considers Mahito evil, even after seeing his experiments in the sewer. Junpei only realizes Mahito's twisted nature when it's too late, moments before Mahito disfigures his body. He enjoys messing with humans, even in battle when his life is on the line. Usually composed, Mahito is shaken when his safety is threatened

Mahito is a human-looking cursed spirit with a patchwork face with heterochromia, as his left eye is dark blue and his right eye is gray. He has long grayish-blue hair that reaches past his neck and is sectioned off into three large strands with ties at the ends. Along with his face, Mahito has stitches all across his body that give him the appearance that he was sewn together. Mahito normally sports a black shawl that is separated into three pieces on the left sleeve. He also wears matching pants with and sometimes without white shoes.

Mahito is a childish unregistered special grade cursed spirit allied with Kenjaku. He born from the hatred and fear from humanity and is also the leader of his own group, consisting of Jogo, Hanami, and Dagon. His group's ultimate goal is the eradication of humanity and ultimately replacing the population with cursed spirits.
