Create a 15-second cinematic action sequence for Seedance 2.5.
Aspect ratio: 16:9, landscape.
Photorealistic mechanical characters in realistic live-action surroundings.
Extremely fast aerial combat, precise weapon contacts, powerful impacts, and spectacular destruction.
PRIMARY VISUAL RULE — SPARK-FREE MECHANICAL COMBAT
Do not generate flying sparks or glowing particle trails anywhere in the sequence.
Show weapon contact through physical recoil, brief camera vibration, metallic sound, and a small cool-white daylight reflection confined to the contacting metal surfaces.
This reflection does not scatter, spray, or leave a trail.
All flying debris must look like solid manufactured material:
silver metal fragments, dark steel pieces, white ceramic chips, recognizable gears, brackets, and electronic components.
Fragments have hard edges, visible thickness, rigid rotation, and gravity-driven trajectories.
Avoid clouds of tiny luminous specks.
Keep destruction effects neutral in color.
No red, orange, yellow, pink, or brown particle effects.
No liquid-like jets, splashes, droplets, dripping, or wet textures.
Dust is pale gray, dry, thin, and slowly settling.
SETTING
Times Square, New York City, in bright midday daylight.
Giant LED billboards, tall commercial buildings, glass storefronts, projecting signs, maintenance platforms, streetlights, and broad intersecting streets.
Blue sky, strong natural sunlight, crisp shadows, and neutral daylight color grading.
The combat area is deserted.
The fighters repeatedly move between street level and several stories above the intersection.
Use walls, columns, billboard frameworks, and elevated platforms as physical rebound surfaces.
Keep the streets visible below during aerial exchanges.
Maintain consistent geography and accumulating damage.
Broken buildings, fallen signs, glass, craters, and rubble remain damaged throughout the sequence.
REFERENCE ASSIGNMENT
REFERENCE IMAGE 1 = A, THE CYBERNETIC ONI SAMURAI.
Preserve the reference silhouette and appearance: tall black horns, ivory-colored armored helmet, red electronic eye details, mechanical respirator, purple and acid-yellow armor, decorative chest plates, exposed machinery, hoses, heavy boots, and mechanical backpack.
The helmet and chest ornamentation are manufactured armor.
A carries two katana matching the reference.
A moves through explosive jumps, wall rebounds, rapid pivots, ballistic momentum, and physical combat.
A never teleports or transforms into mist.
REFERENCE IMAGE 2 = B, THE MECHANICAL REAPER.
Preserve the exact reference silhouette, proportions, color arrangement, markings, hanging fabric, chains, and enormous curved scythe with its suspended vessel.
B is an entirely mechanical construct.
The deer-skull-shaped face is an ivory-colored ceramic mask mounted over a metal head assembly.
The branching antlers are manufactured metal structures with ceramic-coated surfaces.
The rib-shaped chest decoration is artificial armor.
The interior contains gears, motors, circuit boards, brackets, cables, and a central metal chassis.
The hanging costume fabric is synthetic.
Red reference details are rigid painted surfaces or small electronic indicator lights.
Keep the reference appearance while making the construction unmistakably artificial.
B remains visibly taller than A.
Only B can transform into dense black mist and teleport.
Reference colors remain attached to intact armor and equipment.
During the final destruction, emphasize neutral metal interiors and white ceramic fracture surfaces.
Do not turn painted colors or electronic lights into colored particle effects.
Use the references only for character design.
Do not display reference-sheet backgrounds, annotations, detail panels, borders, or duplicate character views.
Do not exchange character identities, weapons, colors, or abilities.
BLACK-MIST TELEPORTATION
B's mechanical body and equipment disappear and reassemble together.
Only one physical B exists at a time.
The antlers, scythe, chains, and accessories always return with B.
Each transition is extremely fast but readable:
solid machine → localized black mist → relocation → mechanical reassembly.
The mist remains monochrome black and charcoal gray, without colored droplets or glowing particles.
B must become physically solid to attack.
A eventually anticipates this reassembly moment.
After the final successful cut, B remains solid and breaks apart mechanically.
ACTION AND CAMERA RHYTHM
Begin at exactly 0 seconds with A already being thrown violently backward and upward.
Start directly inside the action.
Make most of the battle airborne.
Include actual midair sword-and-scythe exchanges, defensive rotations, rapid counters, knees, and kicks.
Maintain strong momentum, powerful arcs, and fast descents.
A redirects movement through contact with structures, weapons, and the opponent.
B attacks through teleportation from above, below, behind, and across A's flight path.
Use motivated cuts around 2, 4, 7, 10, and 13 seconds.
The one-second intervals describe choreography beats, not mandatory cuts.
Continue each shot between those transitions.
Keep silhouettes, weapon contacts, and travel directions readable.

The landing buckles the asphalt beneath both boots.
B's abandoned scythe falls behind A and embeds in the road, splitting a slab.
The suspended vessel and chains swing.
A lowers both katana.
Only scattered mechanical components, white ceramic chips, and dry gray dust remain of B.
The last black mist disperses completely.
Damaged building sections continue falling in the background.
CAMERA:
Continue downward with A's landing.
Settle into a stable low-angle composition with A in the foreground, the scythe behind, and the destroyed intersection beyond.
End on the completed mechanical destruction.
CLIMAX MATERIAL AND MOTION RULES
The finishing sequence must remain clear:
katana cuts artificial armor and chassis → spinning kick collapses the weakened structure → the complete machine shatters into small rigid components.
B's face is a ceramic mask.
The antlers are manufactured metal assemblies.
The chest is an armored machine housing.
All visible interior details are mechanical.
Destruction fragments must have:
hard edges, rigid shapes, neutral colors, visible thickness, independent rotation, and downward gravitational motion.
Prioritize silver metal, dark steel, white ceramic, black cable pieces, and recognizable electronic components.
Use sparse, thin pale-gray dust.
Avoid dense sprays of tiny particles.
Keep red and yellow reference details on intact rigid surfaces only.
Do not create colored trails from damaged armor or electronic lights.
Do not tint airborne debris with red billboard reflections.
No intact enemy figure remains.
B does not regenerate, escape, or reassemble.
The black mist does not replace the physical breakup.
The abandoned scythe may remain separately.
ENVIRONMENTAL DESTRUCTION
Use collapsing building corners, broken columns, falling floor edges, rigid LED screen panels, twisted billboard frames, shattered storefronts, deep road trenches, and craters.
Every destruction event follows visible contact, a collision, a rebound, or falling debris.
Keep concrete, glass, metal, ceramic, and black mist visually distinct.
Preserve enough visibility to follow the fighters.
AUDIO
Use sharp katana movements, heavy scythe movement, dry metallic clashes, mechanical servos, armored impacts, and powerful wall rebounds.
Add glass breaking, concrete fractures, bending steel, falling billboard structures, road rupture, and heavy rubble impacts.
Teleportation produces a short inward rush followed by a compact pressure pulse.
The final cut sounds like ceramic cracking and metal shearing.
The finishing kick produces a dry, powerful crash of armor, gears, ceramic plates, and electronic components.
Mechanical fragments land with distinct clinks and hard impacts.
End with rubble settling and the ringing chains of the scythe.
Background music is optional.
Keep environmental sound and action effects clear and dominant.
No dialogue or narration.
EXCLUSIONS
No flying sparks, glowing particle trails, warm-colored impact particles, or full-frame flashes.
No liquid spray, droplets, splashes, dripping, or wet impact effects.
No blood, biological tissue, real bones, or anatomical damage.
No weightless hovering, prolonged posing, continuous slow motion, or random camera spinning.
No duplicated characters, extra limbs, changing weapons, or identity swaps.
No teleportation or mist transformation for A.
No reference-sheet borders, annotations, subtitles, title cards, or watermarks.
Preserve the reference designs and the recognizable daytime Times Square setting.
