 Compared to the other Espadas, having empathy for the least fortunate hollows that remain as feral monsters, Nelliel has a sense of honor and respect for her opponents who she sees as warriors and only kills within reason.This ideology results with her being attacked by Nnoitra Gilga from behind as part of the Espada's revenge scheme with the help of Szayelaporro's device, managing to crack her mask and tossing her unconscious body out of Las Noches before enough of her spirit energy leaked out to shrink her into current form.But as the resulting amnesia freed her of the sorrow that plagued her, Nel was able to live a carefree life with her two "Fracciones" bent on protecting her from the dangers of Hueco Mundo while making sure she does not remember.
