Zenitsu has fair skin and downturned, worried eyes that range from soft brown to gold and gold, forked eyebrows that fade sharply into a warm orange color. He has short, yellow hair of varying lengths, cut straight at the ends where it fades to a darker orange color, which falls in front of his face in uneven bangs, vaguely resembling a bowl cut.He is cowardly, headstrong, and anxious, often claiming he doesn't have long to live due to the dangerous job of being a Demon Slayer.
