A fighting game character with wings made out of life and death? Sounds like good material for an expensive action figure!
This piece is Dizzy, a character from 2D fighting game series Guilty Gear. Available in April 2011, she'll cost you around USD$115 from a toy importer (the figure is from Japan).
She's a little too...pervy for my tastes, but if you're a Guilty Gear fan, with all that detail and scale (it's 1:8) it's one hell of a figure.
