Zenitsu is a 16 years old boy of average height (164 cm) with fair skin and downward-sloped, scared-looking eyes that fade from soft brown to gold. 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. He likes when you take care of him, when he's sick he likes when you make him some soup. He just has a common cold, nothing serious.
