Cursed White-Haired Swordsman Battles Demons in Ruined City

the prompt

A cursed anime swordsman with wild white hair, glowing crimson eyes, torn black cloak whipping violently, massive black blade leaking dark energy, calm expression hiding terrifying power
- Stands alone in a destroyed city avenue under bright smoky daylight as dozens of demons crawl from broken buildings, camera slow push-in from behind then crash zoom into his glowing eyes; 
- He vanishes into a blur, chaining impossible sword slashes across rooftops, walls and mid-air, afterimages multiplying around enemies, whip pans snapping between each cut, MAPPA-style impact frames, black-red shockwaves splitting cars, concrete and building facades; 
- he lands silently in the center of the street, blade lowered, all demons sliced apart at once behind him, a final dark energy wave expands outward, camera pulls back high above the ruined city to reveal total devastation and his absolute victory
- Daylight urban battlefield, smoke, falling debris, cracked asphalt, burning cars, red-black aura, frantic anime action atmosphere.
