Prompt:

A solitary armored ninja stands on a jagged rock in a rain-soaked plain, silhouetted against a stormy green-gray sky. The armor is dark and highly textured, with subtle glowing gold veins tracing the plates. A tattered cape drapes from the shoulders, and a hooded helm obscures the face. In the right hand, the figure holds a bright RGB katana that glows intensely, casting cool highlights on the wet rock and armor, and his motorcycle that is resting beside him. Heavy diagonal rain streaks sweep the scene while a desaturated green field stretches to the horizon, where an overwhelmingly wide treeline spreads out beyond the empty field under the moody sky. The mood is somber, epic, and cinematic, blending dark fantasy and sci-fi aesthetics. Emphasize realistic textures (metal, fabric, wet rock), dramatic volumetric rain, and high-contrast lighting that highlights the luminous blade against the dark figure. Cinematic concept art, ultra-detailed, photorealistic.
