1girl, she has waist-length long hair, half black and half white, like the boundary between day and night. The snow-white hair strands are smooth like moonlight, while the jet-black long hair is deep like a starless night sky; these two distinct colors achieve a strange balance on her. Her face is delicate and youthful, with the soft contours typical of a young girl, yet showing little emotional fluctuation. Her eyes resemble a long-still lake surface, so calm that one cannot glimpse her inner thoughts. However, her left eye no longer belongs to a human. Dark cracks spread outward from the eye socket, as if eroded by some unknown force, with crimson light faintly seeping from deep within the fissures, like a wound that can never heal, or a seal containing some ancient existence. A crown of thorns woven from black and white floats above her head, not actual metal, but more like condensed light and shadow. Tiny starlights flicker around the crown, yet they cannot dispel the faint, lingering sense of loneliness. She wears a black long dress. The fitted design on her chest is fastened with fine straps, outlining an elegant and solemn silhouette; the hem falls naturally like the night sky, with a slit on one side revealing her slender legs, adding a touch of lightness to the heavy black. Snow-white high-collared lace and cuffs are the only pure white decorations on her entire outfit, like the last remaining light in the darkness. She wears black lace-up high heels, with slender laces wrapping all the way to her calves, adding a sense of mystery and nobility. Most striking are the pair of massive wings behind her, completely different from each other. The right wing is pure white and flawless, with each feather emitting a soft glow, as if still retaining the blessings of heaven. The left wing is pitch-black like ink. The feather edges are ragged and incomplete, as if eroded by countless battles and the passage of time, dark enough to swallow the surrounding light. Black and white are not opposed, but together support her existence. She is neither a pure angel nor a true demon. She seems more like an existence abandoned by both worlds yet unable to be denied by either. She has three pairs of wings. Her body is also surrounded by black halos resembling thorns. The background is an interlacing black-and-white region containing only a massive gothic castle made of black and white, (Beautiful background), (4k, 8k, Ultra HD), (Masterpiece), (Best quality), (High detailed), messy sketch lines, visible construction lines, loose hair strokes, scratchy pencil texture, uneven hand-drawn lineart, delicate ink sketch, rough but beautiful linework, Detail_background,8k,4k, better quality, enhanced details, facade.mix, anime illustration. great quality,best quality
