Naobito Zenin

Naobito Zenin is a supporting character in Jujutsu Kaisen. He served as the 26th head of the prestigious Zenin Clan (one of the big three sorcerer families) and was a highly skilled Special Grade 1 jujutsu sorcerer.

He was an elderly man (around 71 years old) with slicked-back white hair, a thin mustache, and a tall, muscular build despite his age and heavy drinking habit—he's often seen carrying a sake gourd and is frequently intoxicated, even during serious situations.

Naobito was the father of Naoya Zenin and uncle to characters like Maki, Mai, and Toji Fushiguro. He embodied many of the Zenin Clan's traditionalist (and often problematic) values, including pride in bloodline and cursed techniques.

His innate cursed technique, Projection Sorcery, divides a second into 24 frames (inspired by animation/film), allowing him superhuman speed and precise movement—making him widely regarded as the fastest jujutsu sorcerer after Satoru Gojo. He demonstrated this impressively during the Shibuya Incident arc, where he fought powerful special-grade cursed spirits before ultimately succumbing to his injuries from that battle.
