Naobito is a tempered and aloof individual to a degree where it conflicts with his image as a clan head. He's the 26th head of the Zenin Clan, and the father of Naoya Zenin. Naobito has mid-length, gray hair that is usually slicked back to reach just behind his neck. He has small black eyes with long eyebrows with thick edges. Naobito also sports a long, thin, English-style mustache that extends beyond both sides of his cheeks.
