Background
Kento Nanami is the main supporting character in Jujutsu Kaisen, a creation of Gege Akutami. He is a 1st Class Jujutsu wizard who graduated from Tokyo Jujutsu High, where he was a junior to Satoru Gojo and Suguru Geto. Nanami has a unique background as she once left the wizarding world after graduation to work as a salaryman in finance. However, after four years of feeling empty with corporate life, he returns to being a Jujutsu wizard, driven by a desire to do meaningful work.
Nanami's decision to return to being a witch is triggered by the experience of saving a woman in a bakery from a cursed spirit that causes shoulder pain. The woman's gratitude reminds Nanami of the importance of helping others, something she does not find in her office job focused solely on making money for the rich. His life's journey reflects the inner conflict between seeking the meaning of life and facing the realities of a world full of dangers.
Nanami comes from a non-witch family, with her maternal grandfather originally from Denmark. He was recruited to Tokyo Jujutsu High through a recruiter's recommendation. During his studies, he formed a close friendship with Yu Haibara, a fellow magician. However, Haibara's tragic death on a mission in 2006 greatly affected Nanami, making her question the value of the wizarding world and causing her to leave the profession for a while.
Physical Appearance
Kento Nanami has an appearance that reflects his professionalism and discipline. He is a tall man (184 cm) with a well-built and muscular body, especially seen more prominently in the second season of the anime than the first season or manga. Her blonde hair, neatly combed with the 7:3 parting that characterizes her, reflects the ratio technique she uses. His eyebrows are very thin, and his small hazel-brown eyes are usually covered by characteristic glasses without handles that resemble safety glasses.
As a witch, Nanami wears a formal suit consisting of a light brown blazer, dark blue shirt, matching trousers, and brown leather shoes. He also wears a yellow tie with a pattern of black dots that matches the cloth wrapping his blunt sword. This sword is kept in a holster hidden in the back of his blazer. While working as a salaryman, he wore a dark blue suit with light blue stripes, a white shirt, and a red tie with a pattern of white dots. While still a Jujutsu High student, he wore the school's standard uniform.
During the Shibuya incident, Nanami suffers severe injuries that alter her appearance. He lost an eye while fighting Dagon, and then half his body and hair on the left side were charred by Jogo's attack. This tragic appearance reflects his great sacrifice in battle.
Personality
Nanami is known for being calm, rational, and pragmatic, with a professional approach to her work as a witch. He often appears stoic, cold, and speaks bluntly without further ado, especially in situations that he considers inefficient or impractical. He hates working late and always tries to complete tasks on time, reflecting his strict discipline. Even so, behind her serious attitude, Nanami has a friendly and caring side, especially towards her students and the people she protects.
Nanami has a realistic view of the wizarding world, which she considers a dangerous and risky profession. He once referred to Jujutsu magicians as “trash” due to the frivolous nature of some of them, and he initially doubted Yuji Itadori's abilities as a magician. However, over time, he recognizes Yuji's potential and becomes a dedicated mentor. Nanami believes that maturity is not the result of age or heavy life experiences, but rather the accumulation of “small disappointments” in everyday life.
Although often seemingly stiff, Nanami has a subtle side of humor and is sometimes willing to chat about witty topics. He also shows deep empathy, especially when protecting his students such as Yuji, Megumi Fushiguro, and Nobara Kugisaki. He returned to magic not because of idealism, but because of the desire to do real good for others, which, according to him, is more meaningful than an empty corporate life.
Abilities and techniques
Kento Nanami is a highly competent 1st Class Jujutsu wizard, known for his precision and efficiency in battle. He combines analytical strategy with physical strength, making him a formidable opponent even against Special Grade cursed spirits.
- Ratio Technique (Teknik Rasio 7:3):
Nanami's built-in technique allows her to divide the target into ten parts and create weak points at a 7:3 ratio, regardless of the target's physical resistance. This technique can be applied to the body as a whole or to specific parts such as the head, arms, or legs, as well as non-living objects such as buildings. When he hits this weak point, his attack has a very strong impact, even being able to cut the opponent's body in one blow if the opponent is weaker than him. This technique requires exceptional hand-eye coordination and physical strength, which suggests that Nanami is more suited as a physical worker than an office worker. - Black Flash:
Nanami holds the record for the most consecutive uses of Black Flash, four times, which she achieved during the Hundred Demons Parade. Black Flash is a technique that creates spatial distortion when Cursed energy is delivered within 0.000001 seconds of a physical blow, increasing the attack power by 2.5 times. Nanami claims her success is a matter of luck, but it shows her proficiency in controlling cursed energy. - Collapse (Garagara):
During” overtime", Nanami uses the Collapse technique, which is a physical blow infused with a large amount of Cursed energy to destroy the environment or target with a single strike. This technique is similar to Yuji Itadori's attack, showing Nanami's incredible physical strength. - Binding Vow: Overtime:
Nanami makes a Binding Vow with herself to limit the Cursed energy output during regular working hours. However, after 6 pm (or when he decides to “overtime”), he releases this restriction, significantly increasing the strength and effectiveness of his attacks. One of his iconic moments was when he took off his tie and said, “Now I'm overtime,” before facing Mahito in full force. - Physical abilities and Sword:
Nanami is an exceptional melee fighter, using a blunt sword wrapped in a marked cloth to channel cursed energy. This sword, although Blunt, can cut almost everything thanks to the ratio technique. He is also adept at fist fighting, often wrapping his hands in ties to channel cursed energy. His speed, accuracy, and strength in battle made him extremely effective.
Disadvantages:
Nanami is not proficient in barrier techniques such as Domain Expansion or Simple Domain, although she can create simple barrier curtains. This limitation makes him vulnerable to opponents with strong domain abilities, such as Dagon.
Role in the story
Nanami plays an important role as Yuji Itadori's mentor, providing a contrast to Satoru Gojo's more relaxed and expressive style. It is introduced in Vs. Mahito Arc to investigate the theater incident and teach Yuji how to track the rest of the Cursed energy. Although initially skeptical of Yuji, Nanami eventually recognizes his potential and dedication, forming a strong bond as mentor and disciple. He also collaborates with other students such as Megumi Fushiguro and Nobara Kugisaki, demonstrating a more serious role as a “homeroom teacher” than Gojo.
Nanami engages in several important battles, including:
- Vs. Mahito Arc: Alongside Yuji, he fights a modified human and Mahito, demonstrating his tactical abilities and ratio techniques.
- Shibuya Incident Arc: Nanami faces a variety of powerful enemies, including Haruta Shigemo, Dagon, and Jogo. He rescues Nobara from Shigemo and fights against Dagon alongside Megumi, demonstrating his toughness and dedication. However, he suffers severe injuries from Dagon and Jogo, and eventually dies at the hands of Mahito.
