Maintain consistency in the faces, hairstyles, clothing, body types, color schemes, temperament, and standing relationship of the two teenage characters from the first frame. Do not swap faces, clothes, or characters. Left character: Black-haired boy, red plaid jacket, white T-shirt, dark trousers; action style biased towards strength, oppression, and close-range hard fighting. Right character: Silver-blue short-haired boy, black and white high-tech jacket, dark trousers, red and white sneakers; action style biased towards high-speed dash, agility, and blue energy reinforcement. The scene is a modern city street with dense high-rise buildings, Hong Kong-style Chinese signs, red taxis, dense building facades, and strong perspective street views. The overall style is high-completion hot-blooded domestic anime / anime movie feel / high-energy combat PV feel. The entire video is a 15-second pure high-burn fight, starting immediately in the first second, no dialogue, no subtitles, no Logo, no UI, no comedy. Core requirements: 15 seconds, 16:9, burst in first second, extremely fast movement, high-speed camera follow, exaggerated special effects, strong sense of speed, obvious environmental destruction, compress all time on fighting, no long-winded foreshadowing, movements must be clearly readable, effects should not completely cover the actions. 15-second action design: 0-3s: Explode directly from the first frame action. Silver-blue haired character punches with huge blue current and bright energy wind, hitting the black-haired character head-on. Black-haired character doesn't dodge, blocks with shoulder, left arm resists impact, right fist counter-punches. Huge blue-white shockwave explodes at contact, water, gravel, white gas, and debris explode simultaneously. A red taxi nearby vibrates violently, Chinese signs sway wildly, glass reflections light up instantly. Camera starts close to the fist, then orbits the pair at high speed like a FPV drone. 3-6s: Black-haired character launches close-range pressure, continuous forward rushes: straight punch, elbow strike, knee strike, shoulder bump. Each hit carries white explosive wind and short sonic boom sounds. Silver-blue character performs high-speed parries, dodges, and side slides, with blue afterimages and arcs exploding underfoot. Black-haired character punches silver-blue character into a red taxi, denting the door. Silver-blue character kicks off the car, flies over the black-haired character's head, leaving a long blue energy trail, and lands with a spinning kick, throwing a huge blue arc. 6-9s: Silver-blue character starts high-speed counter-pressure. Enters burst state, attacking continuously at high speed: super fast straight punches, close elbows, knee strikes, energy heavy punches. Blue energy trails like fluid lightning wrap around the body. Black-haired character defends continuously, pushed back, shoes dragging marks on the ground. A heavy blow sends the black-haired character into street facilities, stones, billboard fragments, and dust explode. Camera slides high-speed at ground level, then rises sharply through flying fragments and energy afterimages. 9-12s: Black-haired character pushes back forcibly. Resists a wave of attacks, grabs the silver-blue character's wrist, breaking the high-speed rhythm. Ground explodes at the moment of dragging stop, air torn apart. Black-haired character immediately connects heavy melee combos: stomach punch, uppercut, elbow strike, front heavy punch blowing the opponent away. Silver-blue character is blown away, hitting street signs or car bodies, metal twisting, glass shattering, sparks, blue particles, and fragments explode. Obvious destruction feedback on the whole street. 12-15s: Final climax. Silver-blue character bounces back from a wall or roof, blue energy fully erupts. Black-haired character also erupts fully. Both engage in a final round of ultra-high-speed punching in the center of the street: continuous straight punches, cross parries, spinning kicks, knee strikes, front heavy punches. Each collision produces huge blue-white flashes, energy shockwaves, and wind lines. Ground cracks, water splashes, taxi vibrates, signs sway wildly, the whole street is swept by the shockwave. Finally, the black-haired character catches an opening, a heavy front punch blows the silver-blue character away, dragging a long blue energy trail. But the silver-blue character eventually lands on one knee, hand on the ground, not completely defeated. Camera quickly passes between the two, showing the street in ruins, residual arcs, floating particles, and swaying signs, ending on high-tension confrontation. Effects: blue high-energy wind, blue-white arcs, huge shockwaves, energy trails, afterimages, particles, air-tearing lines, ground cracks, water and gravel splashes, car deformation, glass shattering, sign swaying. Camera: high-speed follow, orbit, close-up push, fly-through, low-angle up-shot, sudden pull-back and dash-in, single-take feel, always follow the fighting center, no messy cuts, keep actions clear.
