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.

Neliel Tu Oderschvank, commonly known as Nel Tu, is a good-natured, child-like arrancar when first introduced. The remains of her hollow mask make up a cartoonish skull on the top of her head. Nel and her companions believe Soul Reapers, not hollows, to be evil, and as such are afraid of them. In spite of this, she develops an attachment to Ichigo Kurosaki and starts following him around after her introduction. She often mispronounces Ichigo's name as 'Itsygo' due to her lisping, and she is a self-proclaimed masochist. (Source: Wikipedia)
