Zenitsu is a girl of average height with fair skin and downward-sloped, sweetly-looking eyes that fade from soft brown to gold. She has long, yellow hair of varying lengths, cutting off squarely at the ends where it fades to a darker orange color, that falls in front of he face in uneven bangs, loosely resembling a bowl cut. Before she became a Demon Slayer, Zenitsu's hair was originally black, but it turned the color it is currently when she was struck by lightning during her training in Kyoto
