A medium shot, 3/4 view of a mature woman who is an oni demon, standing centrally in a serene outdoor setting. She is an adult woman with a voluptuous figure and huge breasts, possessing two prominent horns protruding from her forehead. Her long, flowing white hair cascades down her back, contrasting with her calm yet commanding expression. She wears a traditional Japanese kimono adorned with intricate cherry blossom patterns, the fabric showing a rich texture of woven silk. A katana is strapped securely to her back, the hilt and pommel visible over her shoulder. She stands with her arms resting naturally at her sides, her fingers gently brushing the fabric of her kimono. The background consists of a soft-focus landscape of falling sakura petals and distant mountains under a dim twilight sky. The image is rendered as a hyperrealistic anime illustration with a sophisticated color palette of soft pinks and deep shadows, featuring cinematic lighting that highlights the luminous quality of her white hair and the delicate details of the kimono's embroidery.
