Gyomei Himejima (悲ひ鳴め嶼じま 行ぎょう冥めい Himejima Gyōmei?) is a major supporting character of Demon Slayer: Kimetsu no Yaiba. He is also a Demon Slayer and the Stone Hashira (岩いわ柱ばしら Iwa Bashira?) of the Demon Slayer Corps. He also serves as the mentor of Genya Shinazugawa.
Gyomei is a hulking figure among the Demon Slayers. He is one of the tallest characters in the series, easily towering over his fellow Hashira. 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 the black and white uniform typical of a Demon Slayer, with an olive green happi draped over his shoulders. He also sports a large-beaded necklace around his neck and carries ojuzu when he is not engaged in battle.
Kiyo Terauchi (寺てら内うち きよ Terauchi Kiyo) is a servant of the Butterfly Mansion.
Kiyo is a girl with light skin and a set of circular, black eyes. She has shoulder-length black hair with thin bangs framing her face, along with two pink butterfly clips on each side of her head.
Kiyo wears a long, white nurse dress tied with a dark, reddish-pink bow around her waist. She also sports white socks and shoes.
After her family had been killed by Demons, Kiyo was taken in by the Butterfly Mansion.
