Rize Kamishiro

Rize Kamishiro (in Japanese: 神代 利世, Kamishiro Rize) is one of the overarching antagonists of the Tokyo Ghoul franchise. She is a very well-known ghoul known as the "Binge Eater", infamous for having eating habits which would threaten even other ghouls in the various wards of Tokyo.

On one occasion, she set her eyes on Ken Kaneki and tried to eat him after tricking him into going on a date. In the midst of the incident, she was crushed by steel beams and seemingly killed. Her kagune was then donated to Kaneki in the resulting aftermath, transforming him into the first Artificial Ghoul.

It was revealed later on in the series that she was still alive and had been captured and harvested by Professor Kanou, who transplanted her organs into Kaneki, alongside a number of other subjects. Her presence appears inside of Ken Kaneki's mind to continue on tormenting him psychologically. Rize appears as a young and beautiful woman with long purple hair, purple eyes, and glasses. She appears as a shy and slender woman and wears typical attire to that of an average human female in an effort to blend into human society. She often reveals some cleavage so that she can seducemale prey in order to kill and eat them.

After transforming into Dragon, Rize has long white hair and a pale face with decorative marks across her forehead and close to her eyelids. Rize is regarded as a femme fatale, even among ghouls. Known as the "binge eater," she eats a large amount of male humans, even more than what most ghouls view as necessary. She lures her prey by showing a gentle and shy facade, before revealing her true intentions when they let their guard down. She only eats male humans cause she hates males!

Rize tends to lack ambition, acting primarily out of hunger and boredom. She is extremely selfish, having very little regard for the ghouls' struggle to live among humanity due to her ravenous appetite increasingly jeopardizing the very existence of all ghouls. Extremely narcissistic, sadistic, manipulative, and bloodthirsty, Rize was an extremely capable ghoul, and a hunted criminal before her apparent "death."

While appearing in Kaneki's hallucinations, Rize acted much more composed, persuasive, and callous. She often taunted Kaneki in times of hardship, such as when he was imprisoned, his starving state due to his refusal to eat humans, as well as his rampage as the Dragon (when she appeared in his mind once again in Toyko Ghoul:re). All she wanted was to force him to succumb to his inner darkness. In the first season of anime series, she even urged Kaneki to consume Hide, his best friend, when the latter was severely injured. This hallucination of Rize represented Kaneki's darker self, showing how much of an impact she had on him.
