Rize Kamishiro (神代 利世, Kamishiro Rize) is a ghoul that escaped from the organization V, and the foster daughter of Matasaka Kamishiro. She is known under her nickname Binge Eater (大喰い Ōkui, Binge Eater or Gluttony, literally Big Eater). Because of her eating habits, Rize was a threat to most ghouls of the 11th Ward and 20th Ward. She is the donor of the kakuhous that were used to transform Ken Kaneki, Kurona Yasuhisa, and Nashiro Yasuhisa into one-eyed ghouls.
