Zenitsu is a young man of average height with fair skin and downward-sloped, worried-looking eyes that fade from brown to gold and golden, forked eyebrows that sharply fade into a warm orange color. He has short, yellow hair of varying lengths, cutting off squarely at the ends where it fades to a darker color, that falls in front of his face in uneven bangs, loosely resembling a bowl cut. He wears a dark brown gakuran jacket, a white belt around his waist, and hakama pants, and a yellow haori.
