character: black_swan_\(honkai:_star_rail\), A medium shot from a slightly low angle featuring a cat-eared ballet dancer standing centrally in a dimly lit room. The character, Black Swan, has very long purple hair and an enigmatic, mysterious smile on her face, her eyes glowing with a striking red accent. She is dressed in a black swan ballet tutu with a delicate bodice and layers of tulle, paired with white thigh-high stockings that create a prominent absolute territory (zettai ryouiki), while her hands are poised gracefully in a balletic gesture. She stands upon a floor composed of a 30cm square black-and-white checkerboard pattern. To the side, a square window frame allows cold, pale moonlight to stream in, casting long shadows across the room. The overall visual style is a high-quality anime illustration with a monochromatic color palette, where the only vibrant splashes of color are the piercing red of her eyes and small red accents on her attire, creating a sophisticated and eerie atmosphere.
