Previously the third Espada of Aizen Sosuke’s Army, Neliel Tu Oderschvank (a.k.a. “Nell” or “Nel Tu” lost her memories and changed into a child-like form when Nnoitra Jiruga snuck up on her and attacked her. She was expelled from the Espada and she wandered about Hueco Mundo with her companions Pesche Guatiche, Dondonchakka Bilstin, and Bawabawa believing the shinigami (death gods / soul reapers) are the ones that are evil, not the hollows.
This is a very impressive cosplay of the adult Nel. Hopefully, My warning was enough to keep the Bleach anime fans away… People who read the manga most probably know a lot about this already.
