Bleach character. Originally incorrectly romanized as Neliel Tu Oderschvank, the former Tres Espada. She is also known as Nel Tu and she is a small, good-natured, childlike Arrancar. She lives in the desert of Hueco Mundo with her adoptive brothers and former Fracción, Dondochakka Birstanne and Pesche Guatiche, and their pet, Bawabawa.
She can transform into an adult at will.
Often paired with Tier Harribel due to her losing the #3 Espada title to her after the battle with the latter.
