Chiyuki

The Black-Haired Woman (黒髪の女 Kurokami no Onna), sometimes referred to by fans as Onna, is an amnesiac woman taken in by Nona to Quindecim and hired as Decim's assistant. Later, her real name is revealed to be Chiyuki (知幸 Chiyuki).

Chiyuki is an attractive pale-skinned young woman with shoulder-length black hair that has a single white streak on the right side of her bangs, as well as light violet eyes. Her complexion is fair, and while it isn't deathly pale, it contrasts well with her cherry tinted lips. Her slender and semi petite figure is accentuated with a black crop top, a mini skirt held up by a white belt, ankle strap heels, a necklace and a white bracelet.
