Kento Nanami ( (なな) () (けん) () Nanami Kento?) is a supporting character in Jujutsu Kaisen. He is a Grade 1 Jujutsu Sorcerer and a Tokyo Metropolitan Curse Technical College alumni.

Nanami is a well-built man with light-brown hair styled with a neat part. Nanami has very thin eyebrows as well as small eyes that are usually covered by his signature sunglasses, which don't have arms.

Befitting a former office worker, Nanami is usually fully dressed in a business suit. His usual suit consists of a white dress shirt underneath a tan blazer with matching slacks and light shoes. Attached to his dress shirt, Nanami's blunt sword is usually attached to his back by a holster hidden by the blazer. He also sports a necktie that shares the same dotted pattern as the bandages around his blunt sword.

After graduating from Jujutsu Technical School, Nanami wore a vertical striped jacket over a white button-down shirt and dark-colored tie with white dots all over it, vertical striped pants, and black shoes. Nanami's hair was also styled slightly differently when he was younger.


Nanami is a very intelligent and reserved man who at first appears to be someone who is just very serious about his work. He knows how to separate sentimentalism from service and claims he's only a Jujutsu Sorcerer because it's slightly less idiotic than regular careers. As one of Yuji's mentors, Nanami is a complete contrast to Gojo, who is far more outspoken and easy-going.

Nanami's stoic personality in contrast to Gojo.

Nanami almost always has an indifferent attitude, often appearing to very aloof and stoic in every situation. He's very blunt and most of the time is easily irritated, especially when dealing with Yuji.

Beneath his tough exterior, Nanami is a kind man with good moral values. He's truly just a man worn down by the mundane day to day practices of life that stole his youth from him and transformed him into an adult. He treats Yuji like a kid because he doesn't want to see him let go of his youth just for the sake of becoming a Sorcerer.

Nanami quickly becoming irritated with Mahito.

Nanami knows being a Jujutsu Sorcerer is a dangerous and demanding job for crazy people, and so he has a hard time respecting Jujutsu Sorcerers. Even though Nanami and Gojo are longtime friends, the former claims he doesn't respect him either despite their mutual trust in one another. He also initially refuses to acknowledge Yuji as a Jujutsu Sorcerer until Yuji saves his life.

Originally an office worker, Nanami left his old career because he never felt truly appreciated, and his work had no impact on anyone. On the other side, his service to those as a Sorcerer has garnered small bits of appreciation from innocent people. This was more than enough to sway him back to being a Sorcerer and allows him to live a life without regrets.

Abilities and Powers

Overall Skill Level: With a Grade 1 power ranking, Nanami is considered to be among the top class of Jujutsu Sorcerers at Jujutsu High. He is respected by other high-level sorcerers such as Ino, Ijichi, and even Gojo, who hand-picked Nanami to help mentor Yuji. Mahito, a Special Grade Cursed Spirit, considers Nanami to be far stronger than the average Jujutsu Sorcerer, and a true threat, even if he's not incredibly strong like Gojo is

In Shibuya, Nobara noted that Nanami is a true Grade 1 Sorcerer, admitting he's on a completely different level than herself and the other students. He effortlessly dominated a Curse User that had been giving several Sorcerer's trouble.

Master Swordsman: Nanami mainly utilizes a blunt sword in battle and does so with incredible proficiency. Combined with his Cursed Technique, Nanami can cut through anything, including a blocking opponent that is using Cursed Energy to defend itself Nanami wields his blade with grace and balance striking with extreme speed and precision with every swipe of his sword.

Great Tactical Intellect: Nanami's greatest asset in battle outside of his Cursed Technique is his astute fighting instincts and deductive reasoning skills. Both times he fought Mahito Nanami knew he was outmatched in terms of raw Cursed Energy, however, he survived both bouts and overwhelmed Mahito on several occasions thanks to quick thinking and masterful execution.

Nanami instantly realizing his situation inside Mahito's Domain.

When Nanami was assigned Mahito's case, he was able to effectively utilize his team to track down the proper clues that eventually lead them right to Mahito. He was also able to recognize that Mahito was purposely leading them into his hideout, and decided to go alone to prevent harm from coming to the others.

During their first encounter, Nanami eventually realized his Cursed Technique could not win against Mahito's. As a countermeasure, Nanami used the environment around them to pin Mahito down. In their second fight, Nanami quickly realized that Yuji could land attacks that actually damaged Mahito. Instantly, Nanami came up with a strategy to overwhelm Mahito together that completely worked, and if not for Mahito's sudden evolution, would have killed the Special Grade Cursed Spirit. At the mercy of Mahito's Domain Expansion, Nanami was able to instantly assess his situation and what it meant for Mahito's advantage.

Superior Precision & Technique: Nanami is an extremely technical fighter who plans on using his every move to exploit an opening in his opponent. His aim is always extremely precise, as he never misses his target's weak point when it's exposed by his Cursed Technique. Against stronger opponents, Nanami fights by breaking them down and creating constant weak points until they eventually fall. This same level of precision allows Nanami to evade his opponent's attacks with clever maneuvers. For example, by sticking his sword into a wall, Nanami was able to raise his legs high enough to avoid an attack from Mahito.


Cursed Energy Manipulation
Great Cursed Energy: Nanami appears to have high reserves of Cursed Energy that he's able to control through his Cursed Technique with great efficiency. After using his Cursed Technique repeatedly in battle, Nanami has yet to show any signs of tiring himself out. Even after getting injured in his first fight with Mahito, he was able to utilize his Collapse maneuver, which utilized his Cursed Technique to an even greater degree than before.

In addition, Nanami has such precise control over his Cursed Energy that he even subconsciously protects his soul with it, something that was revealed when Mahito tried to reshape his soul with Idle Transfiguration. Nanami's Cursed Energy is normally restricted by his Binding Vow. The full power of Nanami's Cursed Energy was enough to even intimidate Mahito.

Black Flash (黒閃 Kokusen?): A technique that creates spatial distortion when a user connects with an impact of Cursed Energy within a span of 0.000001 seconds of a physical hit. The phenomenon causes Cursed Energy to flash black, creating an attack that is equal to a normal hit to the power of 2.5. Before Yuji fought Hanami, Kento Nanami was the record holder for most consecutive uses of Black Flash. He claims he got lucky.
Binding Vows

Nanami limits the amount of Cursed Energy he can utilize during the time he's officially on the clock working for Jujutsu High. Once he goes beyond his normal shift and overtime hours begin, Nanami's Cursed Energy swells to a great degree and grants him a boost in fighting power.

Innate Technique
Nanami breaking Mahito's arm.png Ratio Technique (十劃呪法 Tookaku Juhō?): Nanami's Innate Technique can divide his target with ten lines and forcibly create a weak spot at the ratio point of seven to three. The target's lines don't have to match up with the target's length or wingspan. Nanami can freely choose which part to divide, including the subjects, head, torso, arms, and legs. This technique is also applicable to non-living objects.
Collapse (瓦落瓦落 Garagara?): An Expanded Cursed Technique that creates a large weak point in the surrounding environment, allowing Nanami to destroy it with a single blow. Nanami first used this technique after unleashing both his Binding Vows in order to destroy the underground tunnel and trap Mahito.[3] Nanami's Ten Stroke Cursed Ritual Rattle.png
