Isolated Japanese Snow Plain with Crystal Knight and Undead Samurai

Isolated Japanese snow plain in the middle of nowhere, surrounded on every side by suffocating thick white-grey fog. NO horizon visible, NO mountains, NO Mt Fuji, NO landmarks. Beyond the fog: featureless pale grey-white void. Heavy dark storm clouds visible only at the very top of the sky, fading downward into the storm. No sun. Heavy snowfall. Ground rich with Japanese texture: tall dry susuki grass tufts with puffy beige seed-heads, dome-shaped red-leaf shrubs with crimson tiny leaves through snowdrifts, small red flowering sprigs, mossy grey rock outcrops with snow on top, scattered fallen red leaves drifting in clusters across the snow. Ground rolls in uneven drift waves. Environment only. Roco, the Crystal Knight. Adult human male of normal height (~1.8m / ~180cm), encased in massive crystal armor. Translucent deep blood-red faceted crystal armor over the entire body, internal crimson glow within the crystal mass, sealed crystal helmet with narrow visor slit. Inside the visor slit: LIVING HUMAN EYES - normal pupils, iris, catch-lights. NO glow, NO red light from the visor. Crystal greatsword fused into the right gauntlet - translucent blood-red geode, faceted, jagged edge, internal crimson glow. Same material as armor. Character. Crystal shield ALREADY GROWN on Roco's left forearm at start of shot - same blood-red crystal as armor and sword, dense outward-radiating jagged crystal spikes (sea-urchin crown), already showing accumulated impact cracks across the surface from previous blocks.
