A medium shot from a low-angle perspective depicts a powerful Japanese Oni demon standing centrally within a misty mountain shrine. The Oni, a muscular yokai with deep red skin, wild flowing hair, and two sharp horns protruding from its forehead, wears a traditional tiger-skin loincloth; he grips a massive, studded iron kanabo club firmly with both hands, leaning forward with a fierce snarling expression. In the background, a weathered red torii gate emerges from a dense, swirling white fog, with jagged mountain peaks faintly visible. The visual style is a unique blend of (sumi-e style:1.4) and (traditional ink wash:1.3), featuring visible ink brushstrokes, bold and thick cel-shaded outlines, and a stylized 3D render aesthetic with soft cell shading. High-contrast chiaroscuro lighting creates dramatic shadows across the demon's anatomy, accented by black ink splatter effects and a monochromatic palette punctuated by the vivid red of the demon's skin and the gate, evoking a powerful and mystical atmosphere.
