A masked divine samurai, shrouded in an aura of mystery, leaps into action, unleashing a devastating attack against his foes with a mystical katana that glows with an inner fire. His full-body armor shimmers with the hues of the galaxy, reflecting the shimmer of distant stars, as plumes of jet-black smoke swirl around him, mingling with bursts of vibrant colors. Set against the grim backdrop of the sengoku period, the scene is painted with incredibly detailed, morbid elements reminiscent of a dark renaissance. Volumetric light pierces through the smoky atmosphere, casting an ethereal glow over the chaotic battlefield. The key visuals, inspired by the styles of Greg Rutkowski and Peter Mohrbacher, capture an ultra-realistic, epic moment in an ultra-wide cinematic shot, as if rendered in the advanced realism of Unreal Engine 5, with a 16:9 aspect ratio composing this breathtaking tableau immersed in otherworldly brilliance.
