A mystical masked samurai divinity in full-body galaxy armor stands amidst a grim battlefield, wielding a katana infused with celestial energy. Plumes of jet black smoke swirl around him, contrasting with vibrant bursts of color as each strike illuminates the morbid scene. Set in the Sengoku period, his presence is epic, detailed with the precision reminiscent of a fusion between Greg Rutkowski and Peter Mohrbacher's styles. The atmosphere is dense with volumetric light, casting an ethereal glow over the dark, chaotic landscape. Realism is paramount, with textures so vivid they belong in a renaissance painting, captured in an ultra-wide, epic shot rendered in Unreal Engine 5. The scene evokes a dark renaissance of mystical warfare, a tableau of power and elegance unleashed in a maelstrom of cosmic beauty.
