Ninja das Sombras com Halo de Brasas

Vertical cinematic dark fantasy illustration of a lone [shadow ninja warrior] standing full-body in a powerful, still front-facing pose on a wet stone rooftop in an ancient Japanese city at night. The figure wears layered, tattered black shinobi robes, a scarf, sash belt, arm wraps, loose hakama pants, and dark boots, with a single katana sheathed diagonally across the back. The face is an anonymous dark void obscured in deep shadow, framed by messy silhouetted black hair against an intense backlight. Directly behind the head hovers a large glowing circular halo of molten orange fire resembling an eclipse ring, while ribbons of flame, ash, sparks, and swirling black smoke coil around the body. Wet reflective stone tiles glisten beneath burning embers at their feet. In the background, a dramatic night sky features storm clouds, a bright full moon on the left, distant pagoda rooftops, and a ruined city skyline. Palette of deep black, charcoal, and intense ember orange with high-contrast rim lighting, glowing lava cracks through the clothing, and dense volumetric atmospheric smoke. Painterly fantasy concept art aesthetic, sharp textures, no text, no watermark.
