Rize is a girl with glasses that Kaneki encounters, who tries to eat him after luring him out on a date with her. Parts of her body are transplanted into Kaneki after she is struck by a fallen i-beam. Before the i-beam incident Rize was a very powerful, fearless and merciless ghoul, often preventing other ghouls from hunting in areas she stole from them. Before she came to the 20th ward, she wreaked havoc in the 11th ward attracting the Anti-Ghoul Investigators to it. Before leaving she killed the ghouls that were in charge and caused a shift in power. She is known as the "Binge Eater" by investigators and like Kaneki she was very fond of reading. Originally believed to be killed during her encounter with Kaneki, later it is revealed that she is still alive and her body was used to produce materials for Ghoul/Human experiments, and Kaneki's transformation into a ghoul was the result of one of them.
