Volcano oni

character: ibaraki_douji_(fate). A low-angle medium shot portrays an elegant oni woman standing powerfully in the foreground, gripping a katana with her left hand, her sharp claws visible. She has glistening red-crimson skin, wild unkempt deep purple and gold hair, one large curved horn wrapping backward, glowing red eyes, and a cruel predatory grin revealing sharp fangs. She wears tattered traditional Japanese demon attire, a kimono with bare shoulders, featuring a midriff and cleavage exposure, while her bare, clawed feet plant firmly on the ground. The background depicts a dark, stormy fire mountain landscape at night, with jagged rocks, swirling mist, and distant lightning illuminating her silhouette. The scene is filled with many purple glowing butterflies in the air. The atmosphere is defined by a hot red light ambiance and dramatic lighting, rendered in a mature anime style with glossy, high-finish rendering, soft lighting, subtle skin gradients, warm highlights, and an intimate, sensual mood with controlled color harmony.
