Masterpiece, extremely high quality, ultra-detailed dark fantasy anime illustration, full-body character portrait of Shuramaru, a beautiful Japanese female oni warrior in her awakened Oni Mode.
She has long vivid crimson-red hair tied in a high ponytail, with wild flowing strands,pale skin, a cold and intimidating expression, and two sharp black-red oni horns growing from her forehead.
Her right eye remains human and deep red, while her left eye is fully exposed as a mechanical cybernetic eye: the skin around the left eye is partially opened and broken away, revealing intricate black metallic inner mechanisms, fine mechanical plates, tiny gears, cables and artificial muscle fibers beneath the skin. At the center is a brilliant deep-crimson artificial iris, glowing like a demonic camera lens. The mechanical structure should look elegant, precise and disturbing rather than grotesque.
She wears a luxurious black Japanese kimono with dark red lining, decorated with intricate traditional red, gold and crimson floral patterns. The kimono is slightly battle-damaged but still beautiful and refined. Black thigh-high boots, ornate obi belt, subtle metallic armor details.
She holds a Japanese katana with a black-and-red hilt, the blade reflecting a faint crimson glow. Her stance is calm and confident, as if she does not need to move quickly to defeat her opponent.
Behind her, a huge shadowy oni face gradually emerges from the darkness, barely visible, with glowing red eyes and large fangs, creating an unsettling supernatural presence.
Atmosphere: dark Japanese shrine at night, old torii gates, faint red lantern light, black shadows, thin mist hugging the ground, restrained crimson oni-fire around her feet.
The scene should feel cool,dangerous, mysterious and slightly frightening, not excessively monstrous. Shuramaru must remain beautiful and elegant even in Oni Mode.
