A masked mystical samurai fiercely battling his foes with a mystical katana, shrouded in an aura of star-speckled armor and swirling jet black smoke, set against an epic winter battlefield from the Sengoku period. The scene is enveloped in morbid, dark tones with a renaissance touch, illuminated by strands of volumetric light. The landscape is richly detailed, featuring crimson red puddles and an atmosphere heavy with tension. This highly realistic, incredibly detailed, ultra-wide epic shot is captured in digital art, inspired by the styles of Greg Rutkowski and Marc Simonetti, reminiscent of Unreal Engine 5's award-winning visuals.
