A full-body portrait shot from a three-quarter low angle captures a mysterious anime girl standing serenely in a dimly lit ethereal void, her ultra-long white hair cascading ankle-length with bangs slightly covering her dull, narrowed red eyes that lack any light or shine, revealing subtle fangs. She is 169cm tall with a slender build and B-cup bust, adorned with long red claws on her hands resting naturally at her sides, massive black feathered wings folded behind her back, and a black tetartoid four-pointed star halo floating above her head. She wears oversized, baggy black clothing that drapes loosely over her form, with wide sleeves and hems pooling around her feet. The minimalist background features faint glowing particles and soft mist. Anime illustration style with great quality and best quality, intricate linework on hair strands,feathers, and fabric folds, subtle shading on skin and cloth textures, cool monochromatic palette dominated by whites, blacks, and muted reds, soft volumetric lighting casting gentle shadows, serene and melancholic atmosphere.
