Sia, a beautiful oni girl with silver bob hair, vivid red eyes, and black-rimmed glasses, with large elegant horns growing from her head that transition from black to deep crimson with fine cracks and glowing red spiritual energy. She is floating on her back on a quiet water surface, sleeping peacefully but with tears silently flowing from her closed eyes, creating small ripples in the water. Her silver hair spreads like a fan across the water. She wears a Japanese-style dark fantasy oni outfit consisting of a black kimono and a deep crimson haori embroidered with red spider lilies. Her hair is adorned with crimson spider lilies, black ribbons, thin chain ornaments, and red gemstone accessories. The water is dark and transparent, reflecting deep purple and crimson light, with red spider lilies, fallen petals, small red lanterns, and moonlight floating around her. The background is a fantastical night forest with a large red moon visible through the trees, mist drifting over the water, and a distant, warm light from a human village. 4:5 vertical composition, high-angle shot focusing on her face, silver hair spreading across the water,cinematic lighting, ultra-high-definition Japanese anime dark fantasy style, emphasizing deep sadness,loneliness, and fragility.
