A cloaked celestial samurai stands amidst a chaotic battlefield, his face obscured beneath an intricately designed mask that conceals divine wisdom and fury. Clad in full body armor crafted from shimmering galaxies, his presence is both awe-inspiring and terrifying. The armor reflects distant stars, and plumes of jet black smoke swirl around him as he moves with ethereal grace. In his hands, a mystical katana hums with otherworldly energy, each swing releasing vibrant blasts of color that cut through the grim darkness of the Sengoku period setting. The scene is rich with morbid detail, capturing the somber brutality of war. Volumetric light pierces through the thick charcoal clouds, illuminating the complex textures and colors of the battle. It's an atmospheric tableau, where the ethereal and the corporeal merge in an artistic dance reminiscent of both Greg Rutkowski and Peter Mohrbacher's distinct styles. The epic 16:9 composition utilizes Unreal Engine 5's capabilities, offering a highly realistic, ultra-wide shot that captures the clash of mortal and divine forces in exquisite detail.
