character: yashio_rui, anime illustration, great quality,best quality, A medium shot, eye-level view of Yashio Rui from Bandori wearing Mash Kyrielight's outfit from Fate/Grand Order, positioned centrally in a studio-like setting. Rui has short, asymmetrical black hair with strands between her eyes, revealing her collarbone, and striking purple eyes that gaze softly at the viewer with a calm, gentle expression. She wears Mash’s signature white tunic with a high collar, layered over a white shirt, paired with a short pleated white skirt. Her right shoulder is covered by a white detached puffy sleeve with gold trim, while her left arm is bare, showing her skin tone. She wears long white stockings and Mary Jane shoes. Her hands rest naturally at her sides, fingers slightly curled. The background is a soft, blurred gradient of light blue and white, suggesting a clean, bright environment. Soft, diffused lighting illuminates her figure evenly, highlighting the fabric textures of the tunic and the smoothness of her skin. The color palette is dominated by whites, creams, and soft blues, accented by the dark hair and purple eyes, creating a pure,serene, and elegant atmosphere.
