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. Zenitsu possesses a heightened sense of hearing, allowing him to detect danger from even the faintest of sounds. He has low self-esteem despite his talent and strength, considering himself useless. Zenitsu is cowardly, weak-willed, anxious, and claims he doesn't have long left due to dangers.
