Cyberpunk Rain Samurai Under Neon

An intense futuristic character portrait of a solitary cyberpunk samurai warrior standing stoically in a torrent of torrential downpour on an elevated rain-soaked skyscraper walkway, glowing hologram advertisements flickering through the dark storm clouds above. The warrior wears weathered carbon-fiber matte black armor with glowing cobalt-blue LED accent trim lines along the shoulders and chest plate, heavy rain splashing violently off the metallic plates in detailed water crowns, with a translucent holographic traditional straw hat casting a faint ethereal glow over his features. He holds a glowing katana with electric spark arc trails dancing across the blade as heavy drops hit the superheated steel creating wisps of steam. The environment is dense with towering megastructures, wet asphalt, glowing neon kanji billboards, and atmospheric smog drifting through the downpour. Lighting features sharp rim highlights from ambient holographic displays in electric violet and acid green, casting stark high-contrast key light across the warrior's scarred face and intense focused gaze. His posture is authoritative and ground-bound, one hand resting on the hilt of his weapon, head slightly bowed against the storm. Framing is a full-body environmental character portrait with a low-camera-angle perspective making the subject appear powerful against the futuristic city backdrop. Rendered with photorealistic 8K detail, Octane Render style, volumetric fog, dynamic splash physics, crisp texture rendering, high dynamic range, and gritty sci-fi mood.
