Tonka

Touka is one of the many ghouls in Tokyo Ghoul, (many alive, many dead) Touka wears a rabbit mask while hunting or while attacking one of the ghoul investigators. Touka in one of the many episodes of this series takes a chunk out of Kaneki after getting permission by him, after she takes a chunk out of him, she then screams/yells at the ghoul cannibal dude and attacks him, (For possibly 25/45 minutes) after they finish killing each other, and only one stands while the other is heavily injured on the ground. She then goes back to Kaneki and brings him back to the HQ (or should I say the cafe) and then helps heal him up. Touka helps Kaneki Heal Hide in one of the many episodes by bringing in food and water while Kaneki's healing him.
