Kento Nanami

Overview

Kento Nanami is a Grade 1 Jujutsu Sorcerer appearing in Jujutsu Kaisen and Jujutsu Kaisen 0. As a graduate of Tokyo Jujutsu High, he temporarily left sorcery to work at a financial firm before returning to the profession as a free agent. Being a junior to Satoru Gojo, Nanami is portrayed as a pragmatic and responsible adult who acts as a dependable mentor and guide to younger sorcerers like Yuji Itadori.

Appearance

Standing around 184 cm tall, Nanami is a tall man with short blonde hair neatly styled in a 7:3 side part. He wears distinctive armless goggles over his eyes and dresses in a beige business suit with a collared shirt and a leopard-print necktie. In combat, he carries a blunt, cleaver-like blade wrapped in talismanic cloth.

Personality

Nanami is composed, highly disciplined, and governed by strict principles of responsibility. He views both corporate employment and sorcery with cynical realism, harboring a deep distaste for working past his regular hours. Despite his stern exterior and blunt demeanor, he possesses a deeply compassionate nature, taking his duty to protect and guide younger sorcerers very seriously. While he completely trusts Satoru Gojo's competence, he openly admits to lacking respect for his frivolous personality.

Abilities

Nanami utilizes the innate Ratio Technique, which forcibly carves a weak point at a 7:3 ratio along any target's length, enabling high-critical close-quarters attacks against both living creatures and objects. He can employ the extension technique Ratio Technique: Collapse to destroy surrounding structures with cursed energy. Through a personal Binding Vow tied to his working hours, his cursed energy is restricted during standard time and substantially boosted during overtime. Though he struggles with barrier techniques, he holds a renowned record for executing four consecutive Black Flashes.

Background

Having a Danish grandfather, Nanami attended Tokyo Jujutsu High alongside his classmate Yu Haibara. Following Haibara's tragic death on a mission and the shift in his environment, Nanami left sorcery after graduation to work as a salaryman at a stock brokerage. Burned out by the corporate world, a chance encounter where he erased a low-grade curse for a bakery worker made him realize his desire for meaningful work, prompting his return to jujutsu sorcery.

Relationships

Nanami maintains a dry professional boundary with Satoru Gojo, trusting his strength without admiring his character. He acts as a key mentor to Yuji Itadori, recognizing the youth's integrity and shielding him from harm. The loss of his classmate Yu Haibara profoundly impacted his early life. He is deeply revered by Takuma Ino and respected by Kiyotaka Ijichi, while standing in sharp opposition to the special grade curse Mahito.

Trivia

Nanami's character concept was conceived around the idea of a former office worker, with his name directly referencing the 7:3 ratio of his technique. In his personal time, he enjoys cooking at home, drinking alone, and reading books, with bread and ajillo being among his favorite foods. In various mobile game crossovers, his combat mechanics often reflect his signature overtime power boost after 6:00 PM.
