Kento Nanami
Kento Nanami appears as a side character in Jujutsu Kaisen. He attended Tokyo Jujutsu High School and was a classmate of Satoru Gojo and Suguru Geto.
Nanami left Jujutsu High after graduation to work as a salaryman but returned four years later to resume her job as a jujutsu sorcerer. Nanami exemplifies what a grade 1 jujutsu sorcerer should be. Nanami is admired by Yuji and Takuma Ino for his calm temperament when confronted with a difficult problem, as well as his remarkable competence in solving it.
It's easy to dismiss Kento as a mild-mannered salaryman, yet appearances can be deceiving. Behind his clean appearance and monotone speech lurks a cold-blooded combatant with years of experience. Nanami primarily fights with a dull blade and does so with great skill. When combined with his cursed skill, Nanami can cut through anything, including a blocking opponent who is defending themselves with cursed energy.
Kento Nanami has excellent control over his cursed energy, and his two Binding Vows, Overtime and Revealing One's Hand, give him even more strength, allowing him to blanket his entire body in cursed energy. Before Yuji, Kento held the record for the most consecutive Black Flash uses, but it is not even his preferred technique. His signature skill, the Ratio Technique, allows him to exploit a weak area wherever on his opponent's body. Kento is a tremendously formidable sorcerer with so many tricks under his sleeve.
