Rize Kamishiro (神代 利世, Kamishiro Rize) was a ghoul and the foster daughter of Matasaka Kamishiro.

Born into the Washuu Clan, Rize was the illegitimate daughter of former CCG chairman Tsuneyoshi Washuu where as a child she escaped from the clan and organization V.

She was known under her nickname Binge Eater (大喰い Ōkui, "Binge Eater" or "Gluttony", literally "Big Eater"). Due to her eating habits, Rize was a threat to most ghouls in various wards in Tokyobefore her death in the Steel Beam Incident where her kakuhou was used in the kakuhou transplant surgery to transform Ken Kaneki into a one-eyed ghoul.
