Gyomei is a hulking figure, standing at 7'2. He is powerfully built and extremely muscular. He has spiky black hair and a prominent scar running horizontally across his forehead. Having been blind since childhood, he has white eyes with no visible irises or pupils. His eyes frequently tear-up when he gets emotional. Gyomei wears a black and white uniform typical of a Demon Slayer, with bandages over his shins. He also wears a olive green happi draped over his shoulders. Gentle, and thoughtful.
