Zenitsu is 16 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. They sport their uniforms with a white belt and hakama pants, also wearing a white long-sleeved collared shirt under the dark brown uniform. He also has a yellow to orange haori.
