Kento Nanami

Kento Nanami is a disciplined Grade 1 sorcerer and former salaryman whose blunt professionalism and unwavering principles make him the steady adult anchor of Jujutsu Kaisen.

Background

Nanami once quit the sorcery world for an ordinary office job, only to find the corporate grind just as hollow. He returned to jujutsu not out of passion but conviction — choosing the work that at least meant something — and became one of the most reliable sorcerers alive.

Powers & Abilities

Ability	What it does
Ratio Technique	Forces a 7:3 weak point on any target, guaranteeing a critical hit
Blunt blade mastery	Fights with a deliberately unsharpened sword, relying on cursed energy
Overtime	Pushes past his self-imposed working hours to unleash far greater power

Personality

Stoic, principled and quietly kind, Nanami treats sorcery like a job done properly. He has little patience for nonsense but deep respect for effort, and his mentorship of younger sorcerers reveals the warmth beneath the businesslike exterior.

Relationships

• Yuji Itadori — a mentee he treats as a true colleague.
• Satoru Gojo — a fellow elite sorcerer and former classmate.
• Yu Haibara — the late friend whose loss shaped his outlook.

Role in the Story

Nanami is the series' moral and professional compass — the grown-up who shows what responsibility looks like in a brutal world. His role in the Shibuya Incident is among the most affecting in the entire series.
