character: Original Oni. A impasto-influenced anime painting of a muscular male oni in his thirties, depicted in a bust-up composition against a dark, traditional Japanese room at night with tatami mats and shoji screens. He has long, flowing white hair, large horns with a skin-like texture on his forehead, sharp canine teeth, and piercing blue eyes that glow ominously. He wears an opulent black kimono embroidered with gold thread, which is loosely draped to reveal his broad chest and arms. His expression is sinister, with narrowed eyes and a one-sided evil smile. Viewed from a slightly low angle, as if looking up at the oni, the scene is illuminated by moonlight streaming through the screens, creating deep shadows and dramatic contrasts. The style features pronounced luminous highlights against rich, muted tones, blending a subtle retro flair with Western illustration elements, resulting in a heavy, yokai-like dark fantasy atmosphere with cinematic lighting, high detail, and an imposing sense of presence.
