Nelliel Tu Oderschvank

ネリエル・トゥ・オーデルシュヴァンク, Nel, Nel Tu
Neliel Tu Oderschvank commonly known as Nel Tu is a goodnatured childlike 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 Ichigos name as Itsygo due to her lisping and she is a selfproclaimed masochist. Source: Wikipedia
