Dark Anime Rooftop Fight Sequence

Original premium dark action anime sequence on a rain-soaked rooftop at night, intense sakuga energy, sharp linework, dramatic speed lines, cinematic lighting, hyper-detailed animation. 0–4s: a lone swordsman in a torn black coat lands on a rooftop surrounded by masked fighters, neon city glowing behind him, rain cutting through the air, slow push-in, his blade lowers as enemies circle. 4–9s: sudden explosion of motion, ultra dynamic combat as he dashes through the group with impossible speed, blade clashes, spinning dodges, mid-air pivots, coat whipping violently, enemies crashing across the rooftop, camera whipping with every exchange. 9–15s: the final enemy leaps down with a massive overhead strike, the swordsman slides under it, turns in one clean motion, and unleashes a single flashing finishing slash that freezes the entire frame for one dramatic beat before the opponent falls. End on the hero standing in the rain as sparks and water drift through the air.
