A mystical samurai, face concealed by an enigmatic mask, brandishes a glowing mystical katana amidst a harrowing battle. His star-dusted full body armor gleams with celestial brilliance, interwoven with plumes of deep ebony smoke, contrasting against an epic renaissance landscape. Set in the tumultuous Sengoku period, the scene is enveloped in a morbid and dark atmosphere. Volumetric light pierces through the warfare fog, illuminating a wintry battlefield scattered with crimson red puddles. The style echoes the intricate visuals of Greg Rutkowski and Marc Simonetti, presenting a highly realistic, ultra-wide epic shot akin to an award-winning digital art piece rendered in Unreal Engine 5.
