Ryuma was a samurai from the Wano Country in the New World who died and was made into a General Zombie by Hogback. He is the same Ryuma from Oda's previous one-shot manga, Monsters. His corpse previously possessed Brook's shadow to animate him while on Thriller Bark. When he was alive, he possessed black hair which was tied in the end with a topknot.He also wore a simple khaki samurai gi and simple zōri sandals. As a zombie, Ryuma is noticeably shorter than Brook.He has several bandages covering part of his skull face, which has no eyes and no nose, and wears a samurai gi with intricate designs more detailed than his original garb. He also wears geta instead of the zōri sandals of his past life, as well as a blue stomach band with a swirling design. Ryuma's mouth is partially covered by the blue scarf he wears, his black hair has turned white, and he keeps Shusui strapped to his right hip.
