Some quick little basics:

Height: 5'8 ft
Weight: Probably about 115-120 at most.

She bears an incredibly lean build. Built to run, and to do it well. With long, sturdy legs, always taking incredibly graceful strides.

Hair of an almost snowy shade of platinum blond hints at her heritage, but only just so. Spilling beautiful and wild upon her slender shoulders.

A skin tone of a modest grey, not too dark, and not exactly light. It dances with a very pale sort of blue, only really noticable in the purest light. Lest she meld to a lovely stone-grey.

Upon her back, a pair of untrained and slightly under developed wings. Each one only about the size of a hand, they bear distinct demonic appearance, being almost bat-like. These, coupled with a pair of finger-tip length horns poking from that lovely hair, and the long spaded tail, mark her as some creature from the Nine. Or, at the least, endowed with the blood of one.

A pair of cupable breasts stand perky on her chest, each one only a C-Cup, and the smaller end of even that. Never the less, their roundness, and the lean curve of her waist makes for a delightful little hourglass. (Especially when:) One might notice her hips are slightly wide, almost a bit too wide to be meant for her, were it not for the means that they tapered to those lovely legs, and formed a neat and spectacularly heart shaped behind.
