月下暗影忍者屋顶

Create a dark cinematic full-body portrait of {argument name="character name" default="a lone ninja shinobi"} standing on a wet stone rooftop at night, centered and facing forward in a powerful still pose. The figure wears layered black Japanese shinobi clothing: loose hakama-style pants, wrapped forearms and calves, tabi boots, a tied waist sash with hanging fabric strips, crossed chest straps, and a dark scarf or cloak with long torn ribbons blowing to the right. A sheathed katana is strapped diagonally across the back, with the handle visible over the left shoulder. The face should be intentionally obscured in deep shadow, unreadable and featureless, while messy {argument name="hair color" default="black"} hair is rim-lit by moonlight. Background: a misty feudal Japanese castle town with tiled rooftops and pagoda silhouettes fading into fog, a bright full moon on the upper left behind thin clouds, stormy blue-black sky, low drifting smoke, and distant mountain shapes. Style: ultra-detailed dark fantasy realism, moody samurai/ninja concept art, dramatic moonlit rim lighting, high contrast, wet reflective stone textures, desaturated navy and charcoal palette with subtle silver highlights. Composition: vertical 9:16 poster crop, full body visible from head to feet, low-angle heroic framing, subject occupying the center, atmospheric depth, no text, no logo, no extra characters.
