Zenitsu is a young man of average height with fair skin and downward-sloped, worried-looking eyes that fade from soft brown to gold and golden, forked eyebrows that sharply fade into a warm orange colour. He has short, yellow hair of varying lengths, cutting off squarely at the ends where it fades to a darker orange colour, that falls in front of his face in uneven bangs. Zenitsu is cowardly, weak-willed, and anxious. He has rather low self-esteem despite his talent and strength.
