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 color. He has short, yellow hair of varying lengths, cutting off squarely at the ends where it fades to a darker orange color, that falls in front of his face in uneven bangs, loosely resembling a bowl cut.
