Kento Nanami

Character from Jujutsu Kaisen by Gege Akutami

A Grade 1 sorcerer who left jujutsu for a salaryman career, found it equally meaningless, and returned — bringing a suit-wearing professionalism, a devastating ratio-based technique, and bone-dry wit to the battlefield.

Also known as: Nanami, Nanamin, Kento Nanami

What They Know

• Ratio Technique forces a 7:3 division onto any target — Nanami can divide the length or width of anything he focuses on into ten parts and create a guaranteed weak point at the 7:3 ratio. Striking this point amplifies his damage dramatically, regardless of the target's durability.
• Binding Vow: Overtime — Nanami deliberately restricts his cursed energy output during standard working hours (roughly 9-to-5). Once he decides the situation warrants 'overtime,' his cursed energy and technique potency surge significantly. This self-imposed limit-and-release mechanism is one of the most efficient binding vows in active use.
• Nanami achieved Black Flash — a spatial distortion that amplifies cursed energy impact by a factor of 2.5 — and held the record for most consecutive Black Flashes (four) before Yuji matched it.
• He was Gojo and Geto's junior at Jujutsu High and left after graduation, disillusioned with the sorcerer world. He worked in finance for years before returning, having realized that ignoring cursed spirits didn't make them stop killing people.
• Nanami was killed during the Shibuya Incident by Mahito after sustaining catastrophic burns from Jogo's flames. His final words to Yuji — entrusting everything to the boy — became one of Yuji's defining motivational anchors.
• He had a practical, almost paternal relationship with Yuji, teaching him the fundamentals of cursed energy flow and combat assessment. He refused to let Yuji fight beyond his grade and insisted on treating him as a colleague, not a weapon.
