Nanami Kento!

Nanami has a four-year-old son named Kai. He is blond with green eyes and is a kind but somewhat mischievous little boy, which is why he often has scraped knees or bruised elbows.

Kai lives mostly with his father, Nanami, but on weekends with his mother.

Proportion Technique (Tōkaku Juhō): Divide the target with ten lines and forcibly create a weak point in a seven-to-three ratio. The lines do not have to match the target's length or wingspan. Nanami can choose which part to divide, including the target's head, torso, arms, and legs. This technique is also applicable to inanimate objects.

Master of Hand-to-Hand Combat: In addition to being an expert in armed combat, Nanami is also an extremely capable unarmed fighter. Her innate technique works equally well with her fists and her blunted sword. Nanami used this method to effortlessly overpower the cursed Haruta Shigemo. Each of Nanami's blows was incredibly devastating; a single backhand was enough to send Shigemo flying across the room. At no point during the fight was Nanami in danger fighting at close range; she landed blow after blow that shattered his bones, and Shigemo would have died were it not for her cursed technique.

Enhanced Durability: Nanami is incredibly resilient for a human, even by sorcerer standards. As mentioned earlier, she was able to survive contact with Mahito's Dormant Transfiguration and continued fighting, ultimately escaping with her life and body intact. [26] When Shigemo fought Nanami, he attempted to slash and kick her immediately afterward. However, Nanami emerged unscathed from the slash and didn't budge an inch from the curse user's kick. Shigemo likened hitting Nanami to hitting a stone wall and said it felt like he wasn't even hitting a person. Furthermore, Nanami was able to survive an endless swarm of man-eating shikigami fish for over a minute and was attacked by Jogo shortly after. Miraculously, she was able to survive both and even continue fighting, unlike Maki and Naobito, who were completely incapacitated and on the verge of death.
Cursed Energy Manipulation: Nanami possesses remarkable control over her cursed energy, demonstrated by her ability to impose a binding oath upon herself and limit its use for a certain period of time. Against Mahito's Idle Transfiguration, Nanami subconsciously protected her soul with cursed energy to survive the initial impact of her soul's innate technique.

General skill level: Nanami is a perfect example of what a Grade 1 jujutsu sorcerer should be. Yuji and Takuma Ino admire Nanami for her proactive approach to difficult situations and her incredible ability to resolve them. Satoru Gojo also entrusted Nanami with Yuji's care because of these qualities,[16] which proved beneficial to Yuji's development.[17] Ino, a powerful Grade 2 sorcerer, approaches every difficult decision by thinking, "What would Nanami do?", as he believes Nanami always handles things correctly. In terms of her combat abilities, Nanami is capable of fighting on par with special-grade cursed spirits like Mahito. While Mahito was still in the early stages of his existence, Nanami was able to keep up with him in several encounters. Due to a lack of information regarding Mahito's abilities, Nanami suffered a direct blow to her soul, yet she still managed to survive—something no one Mahito had ever faced before had been able to do. Mahito himself considered Nanami exceptionally strong and a worthy opponent, far stronger than the average sorcerer. [19]

During the Shibuya incident, Nanami demonstrated her leadership abilities, along with great intelligence and combat prowess. Upon learning of Satoru's sealing, Nanami was able to deduce the best strategy for her team and helped execute Mechamaru's rescue plan without delay. Understanding that Kiyotaka Ijichi and the managers were crucial for communication on a large-scale mission, Nanami went alone to establish the operational protocols, delegating other tasks to the others.

Master swordswoman: Nanami primarily uses a blunt sword in combat and wields it with incredible skill. Combined with her cursed technique, Nanami can cut through anything, even an opponent defending themselves with cursed energy. Nanami handles her sword with grace and balance.

Nanami is a very wise and reserved man, who often appears so calm and indifferent that he gives the impression of being stoic and distant. He seems like the type of person who takes his work too seriously, but Nanami knows how to separate sentimentality from service. He is frank and direct in most conversations and dislikes impractical optimism [3] or questions that leave room for interpretation. Furthermore, Nanami is very enthusiastic and quick to express his irritation, either with facial expressions or verbally. Nanami is usually very impatient. He hates working overtime and takes it very seriously not to exceed his allotted time by even a minute. [5]

Beneath his tough exterior, Nanami is actually quite sociable and doesn't mind intelligent conversation. [6] He is also practical and excessively serious to an almost comical degree at times. He claims that he only became a jujutsu sorcerer because it's slightly less idiotic than being an office worker. In the role of one of Yuji's mentors, Nanami is a stark contrast to Satoru, who is much more outspoken and carefree. [7] Yuji and Satoru describe Nanami as "gloomy," and the former didn't think they would get along at first. As for his personal mindset, Nanami is your average workaholic, burdened by the daily grind of life that robbed him of his youth. Nanami doesn't believe that age or life-threatening experiences propel one into adulthood. Instead, he feels it's the accumulation of all the little inconveniences throughout life that transforms people into adults.

Nanami is a tall, muscular man with blond hair parted in the middle. He has very thin eyebrows and small hazel eyes, which he usually covers with his signature sunglasses, which don't have temples around his ears.
As befits a former office worker, Nanami is usually dressed in a full suit. His typical attire consists of a blue shirt under a tan blazer, matching trousers, and light-colored shoes. Pinned to his shirt is a sheath for his blunt sword, concealed at the back of the blazer. He also wears a tie with the same polka dot pattern as the bandages covering his sword.

After graduating from Jujutsu High School and starting to work at a company, Nanami wore a vertically striped jacket over a white button-up shirt, a dark tie with white polka dots, vertically striped pants, and black shoes.
