Ghoul Investigators refer to her as “Rabbit.”
Touka is a ghoul successfully posing as a human and working as a waitress at a cafe which serves as a gathering place for other ghouls, as well as a food resource.
She saves Kaneki’s life at one point and acts as a reluctant guide to him and his adaptation to the ghoul society. She is very serious, tough and hard-working, trying to keep their district as safe for ghouls and humans as possible. Her powers and strength are also quite great and she makes for a formidable opponent.
