Dark Ninja Samurai under Moonlit City AI Image Prompt

Create a vertical dark fantasy cinematic illustration of a lone {argument name="character type" default="shadow ninja warrior"} standing full-body on a wet stone rooftop in an ancient Japanese city at night. The figure faces forward in a powerful still pose, wearing layered black tattered shinobi robes, scarf, sash belt, arm wraps, loose hakama-style pants, and dark boots, with one katana sheathed diagonally across the back. The face is completely hidden in deep shadow as an anonymous dark void, with messy black hair silhouetted against intense backlight. Behind the head is one large glowing circular halo of molten orange fire, like an eclipse ring, while swirling black smoke, ash, sparks, and flame ribbons wrap around the body and robes. Use a dramatic moonlit sky with one bright full moon on the left, storm clouds, distant pagoda rooftops, and a ruined city silhouette in the background. The palette should be almost entirely black, charcoal, and ember orange, with high-contrast rim lighting, glowing cracks of lava-like energy across the clothing, burning embers at the feet, wet reflective stone tiles, and dense atmospheric smoke. Style: ultra-detailed fantasy concept art, samurai-ninja dark sorcery aesthetic, realistic painterly rendering, epic poster composition, sharp textures, volumetric firelight, no text, no watermark.
