A medium shot, eye-level view of a young woman with a mystical presence, standing beneath the sweeping branches of a willow tree. She has long, flowing white hair and striking red eyes that are highly detailed and expressive. She is dressed in a traditional black yukata with subtle patterns, and she holds a traditional oni mask to the side of her head with one hand, while her other hand rests gracefully at her side. The background is dominated by the cascading, slender green leaves of a willow tree, creating a serene and slightly melancholic environment. The visual style features clean linework and a gentle color palette, with smooth, glossy skin tones. The lighting is soft and diffused, filtering through the willow branches to create a tranquil and ethereal atmosphere.
