DURATION: 25 seconds ASPECT RATIO: 16:9 STYLE: Ultra photorealistic live-action supernatural action film, modern Japanese underground subway, premium cinematic VFX, extremely fluid high-speed martial arts choreography, extreme speed contrast, dynamic chase cinematography, dramatic environmental slow motion, powerful readable physical impacts, dark surreal atmosphere. REFERENCE ASSIGNMENT: @IMG1 = HERO @IMG2 = CREATURE HORDE @IMG3 = JAPANESE SUBWAY PLATFORM AND TRAIN @IMG4 = ORDINARY COMMUTERS Use all uploaded references consistently. @IMG1 : Maintain the HERO'S face, black hair, bright blue eyes, black high-collar outfit, body proportions, and realistic appearance. @IMG2 : Use varied monster horde designs, with many different sizes and creature types: large creatures, horned creatures, crawlers, one-eyed creatures, long-limbed creatures, small aggressive creatures, distorted humanoid creatures. Creature internal fluid is DARK GREEN. @IMG3 : Preserve the realistic Japanese subway platform, stopped train, open train doors, columns, tiled floor, yellow tactile paving, signage and fluorescent lighting. @IMG4 : Use normal everyday Japanese commuters with light-to-moderate crowd density. THE MONOCHROME DIMENSION: The entire subway environment becomes pale, washed-out black and white. Black and white liquid ink continuously spreads, smears and splashes across the floor, train, walls, columns and ceiling. The HERO and monsters remain clearly readable against this monochrome environment. CREATURE RULES: Approximately 100 supernatural creatures emerge from the train. Use different sizes and forms. Powerful impacts may release dark green fluid, black particles, horn fragments, shell fragments, armor-like fragments and small supernatural creature fragments. Keep all creature fragmentation stylized and non-graphic. No human blood. No excessive gore. OPENING — CAMERA RUSHES THROUGH THE INVASION 0–3 SECONDS Begin immediately as a subway train finishes stopping beside the platform. Train brakes hiss. Multiple doors slide open simultaneously. Immediately, approximately 100 creatures erupt from the train. They flood violently onto the platform. Some sprint upright. Some crawl. Some leap over other monsters. Some climb around the train doors. Large creatures push through smaller creatures. They immediately attack and chase commuters. The station erupts into chaos. People scream. Passengers run in different directions. Someone falls. Another passenger pulls them back up. A monster chases a businessman. Another monster grabs a commuter. Another creature leaps toward several fleeing people. THE CAMERA MUST NOT STAY STATIC. The camera aggressively flies forward THROUGH the invading monster horde. Pass extremely close to several monsters. Slip underneath one creature's raised arm. Pass beside another monster jumping across frame. Rush past frightened civilians. Continue rapidly through the chaos until the CAMERA arrives directly in front of the HERO. The HERO stands motionless at the center of the platform. Chaos continues everywhere behind him. POWER ACTIVATION 3–6 SECONDS Dynamic push-in toward HERO. Medium close-up. Then extreme close-up of his eyes. His BLUE EYES briefly produce a sharp brilliant blue sparkle. The HERO remains completely calm. He raises ONE HAND. Using one hand, he forms the compact finger-lock gesture. Close-up of the fingers. The HERO clearly says: “Ryōiki Tenkai.” Immediately, the ENTIRE SUBWAY ENVIRONMENT shifts into a PALE MONOCHROME STATE. Color drains from the station. Platform, walls, train, ceiling, lights and passengers become washed-out black, white and gray. At the same moment, BLACK AND WHITE LIQUID INK violently spreads outward from beneath the HERO. Thick black ink races over the platform floor. Large black brush-like streaks sweep across walls. White liquid ink splashes across columns. Black and white ink smears across the ceiling. The effect must resemble REAL LIQUID INK being violently brushed across physical surfaces. The subway architecture remains clearly recognizable beneath the effect. Then TIME DROPS INTO EXTREME SLOW MOTION. EXTREME TIME CONTRAST 6–8 SECONDS Everything except HERO slows dramatically. A running commuter almost freezes. A woman falling toward the floor moves extremely slowly. A dropped phone rotates slowly in mid-air. A monster remains suspended while jumping toward someone. Another monster slowly opens its mouth near a passenger. Dark green droplets float through the air. Black and white ink continues slowly flowing across the station. The HERO scans the platform. He lowers his center of gravity. His torso LEANS FORWARD. One leg pushes powerfully against the floor. He assumes the posture of a sprinter moving at absolute maximum speed. Then— HE EXPLODES FORWARD. MAIN RUNNING POSTURE 8–21 SECONDS THIS IS CRITICAL. The HERO must visually look like he is running at MAXIMUM POSSIBLE SPEED. His torso remains noticeably LEANED FORWARD. Head slightly forward. Shoulders low. Arms aggressively driving backward and forward. Long powerful running strides. Feet push explosively against the floor. His coat and hair react strongly to the speed. He does NOT run upright casually. He looks like his entire body is being driven forward at overwhelming velocity. The HERO attacks WHILE maintaining this forward momentum. He almost never becomes stationary. CAMERA TRACKING — ABSOLUTE PRIORITY The CAMERA is dynamically TAG-LOCKED TO THE HERO. The camera moves almost as fast as the HERO. The HERO remains the visual anchor throughout the main action. Use constantly changing dynamic tracking angles: LOW SIDE TRACKING: Camera races beside HERO'S legs while he sprints. FRONT REVERSE TRACKING: Camera moves backward directly ahead of HERO while he charges forward. OVER-THE-SHOULDER CHASE: Camera follows directly behind HERO while monsters and civilians appear ahead. EXTREME LOW FRONT ANGLE: Camera almost touches the platform while HERO runs directly over the lens. SIDE CLOSE TRACK: Camera flies inches beside HERO while his body leans forward at maximum speed. ORBIT ATTACK CAMERA: During major impacts, camera rapidly swings around HERO and monster. IMPACT CLOSE-UPS: At selected attacks, suddenly CUT VERY CLOSE to HERO'S fist, palm, elbow or hand edge making physical contact. Immediately after impact, camera accelerates back into the running shot. Do not make the entire sequence wide. Alternate between: wide speed spectacle, medium running shots, and extremely tight physical impact close-ups. The HERO MUST NEVER BECOME ONLY A BLUR. Show detailed body mechanics even at extreme speed. CHAOS MUST CONTINUE DURING HERO'S RUN The background must NOT become an empty battlefield. As HERO runs across the platform, continuously show monsters still attacking civilians farther ahead. Examples: A monster chasing a fleeing office worker. A crawling monster pursuing someone who has fallen. Two monsters cornering commuters near a column. A monster climbing onto a bench toward frightened passengers. Another monster pulling at someone's bag. Several commuters running away from creatures near the train doors. The audience must constantly feel that the HERO is racing through an ACTIVE EMERGENCY. He is not simply fighting monsters standing still waiting for him. FIRST RESCUE — INTERRUPT THE BITE A creature has grabbed a civilian. Its jaws move slowly toward the civilian's shoulder. The civilian tries desperately to pull away. The HERO approaches at extreme speed. He remains leaned forward in full sprint. CAMERA SIDE TRACKS directly beside him. At the last instant— CLOSE-UP. The HERO'S fist enters frame at enormous speed. STRAIGHT RUNNING PUNCH. His fist hits the side of the monster's face BEFORE it can bite the civilian. Show clear contact. BLACK INK bursts violently outward. A white liquid pressure ring ripples through the air. Dark green monster fluid scatters. Several small non-graphic creature fragments and shell pieces spin outward. The monster is thrown violently sideways. Immediately return to the tracking camera. THE HERO NEVER STOPS. His punching arm retracts while his next running stride is already happening. SECOND ATTACK — CLOSE-UP HAND STRIKE Another creature lunges toward a fleeing passenger. HERO changes direction without slowing. He leans even lower. Three extremely fast running steps. CAMERA moves directly in front of him. At the last second— EXTREME CLOSE-UP. The HERO uses the EDGE OF HIS HAND in a powerful downward chopping strike across the monster's upper torso. CLEAR PHYSICAL CONTACT. Black ink splashes outward like an enormous brush stroke. White ink erupts underneath the impact. Dark green droplets scatter. Small horn and shell fragments spin into the slowed environment. The creature folds and flies backward. Immediately CAMERA whips back beside HERO. HERO CONTINUES RUNNING. MULTI-MONSTER RUNNING COMBO A group of monsters blocks the route ahead. HERO does not slow down. MONSTER 1: Running straight punch. Close-up contact. Monster launches backward. HERO keeps running. MONSTER 2: Duck underneath its arm while maintaining sprint. Running elbow directly into torso. Monster bends and spins upward. HERO keeps running. MONSTER 3: HERO plants ONE FOOT against a column. Pushes sideways at enormous velocity. Flying side kick. The monster shoots horizontally across the station. HERO lands already leaning forward. Instantly resumes sprint. MONSTER 4: Running palm strike. Large localized black ink explosion. Monster flies backward into another creature. MONSTER 5: HERO approaches at full speed. Brief front camera. HERO shifts sideways. Rapid hand-edge strike. Monster violently spins away. No pause. HERO continues directly into the next cluster. FLUID COMBO SEQUENCE The HERO now moves through many creatures in one long uninterrupted flow. RUNNING PUNCH. Continue sprint. DUCK. ELBOW. Continue sprint. STEP ON WALL. PUSH OFF. FLYING KICK. Land. Immediately lean forward. SPRINT. LOW KICK. Rotate body. BACKFIST. Continue running. PALM STRIKE. Jump. MID-AIR KICK. Land directly into another full-speed sprint. Every attack uses momentum from the previous movement. The HERO never resets into a neutral fighting pose. The choreography feels like one continuous physical sentence. MONSTERS FLY IN DIFFERENT DIRECTIONS Each attack must create a visually different result. Monster A launches vertically upward. Monster B flies horizontally across the platform. Monster C spins backward toward the train. Monster D rotates above the floor. Monster E crashes into another monster. Monster F flies through an open train doorway. Monster G is thrown into a column. Monster H tumbles sideways across the platform. Monster I spins over a bench. Monster J is launched into two other monsters. Use MULTI-MONSTER CHAIN REACTIONS. One punched monster flies backward and crashes into two creatures behind it. All three scatter in different directions. Another creature struck by a running kick spins through a group of monsters and knocks them apart. Because the surrounding world remains extremely slowed, many monsters remain suspended in the air simultaneously. Their supernatural fragments rotate around them. Dark green droplets float. Black and white ink hangs in space. The HERO races THROUGH this field at extreme speed. CLOSE-UP IMPACT RHYTHM Throughout the high-speed combat, insert VERY SHORT detailed impact moments approximately every few attacks. FAST TRACKING SHOT. HERO approaches monster. CUT TO CLOSE-UP. FIST CONNECTS WITH FACE. Ink explosion. Immediately back to running camera. Continue. Then several seconds later: SIDE TRACKING. HERO approaches another monster. CUT TO CLOSE-UP. EDGE OF HAND connects with shoulder / upper torso. Black ink and fragments burst outward. Immediately return to tracking. Later: LOW TRACKING. HERO jumps. CLOSE-UP. FOOT connects with creature. Monster surface compresses from the impact. Dark green droplets scatter. Return to high-speed tracking. The close-ups must make the extreme speed feel POWERFUL and PHYSICAL. BLACK AND WHITE INK TRAIL The HERO'S high-speed movement pulls thin streams of black and white ink behind him. When he runs straight: long horizontal black brush streaks. When he turns: ink bends into a sharp flowing curve. When he jumps: white and black ink curves upward. When he spins: circular black ink brush marks appear briefly. When he punches: ink compresses toward his fist and explodes at contact. When he performs the hand-edge strike: a sharp black liquid brush stroke follows the hand. Do not hide HERO behind ink. HERO always remains readable. TRAIN INTERIOR CONTINUOUS RUN The HERO runs directly into the stopped train. Camera stays locked onto him. He remains leaning forward at full sprint. Inside the train, CHAOS CONTINUES. Passengers hide between seats. A monster reaches toward a terrified commuter. Another creature crawls over seats. Another blocks the aisle. HERO runs directly through the carriage. RUNNING UPPERCUT. Creature launches upward. No stop. Step onto train seat. Wall run. FLYING KICK. Creature flies sideways. Land. Immediately sprint. Slide underneath another creature. HAND-EDGE STRIKE while rising. Close-up impact. Black ink bursts across frame. Continue forward. Another creature approaches. Rapid straight punch. Creature flies backward toward the next carriage. Camera travels through the connecting doorway WITH HERO. NO PAUSE. RETURN TO PLATFORM The HERO bursts from another train doorway back onto the platform. Camera exits directly beside him. The platform remains full of chaos. Some civilians are still escaping. Several monsters remain ahead. HERO increases speed. He races between: fleeing passengers, columns, suspended monsters, floating objects, black ink, dark green droplets, and supernatural fragments. ATTACK. RUN. ATTACK. RUN. ATTACK. Never stop. FINAL RUNNING ASSAULT 20–22 SECONDS HERO reaches the final large cluster. Camera moves in FRONT of him. HERO is leaned extremely far forward. His face is focused. Blue eyes sharp. He pushes into MAXIMUM SPEED. Camera swings beside him. ONE UNBROKEN FINAL COMBINATION: running punch monster 1 continue forward duck monster 2 hand-edge strike monster 2 continue forward kick monster 3 sideways jump over monster 4 downward strike during jump land immediately sprint spinning kick monster 5 one final running palm strike into monster 6. The final strike creates the largest localized BLACK AND WHITE INK IMPACT of the combat sequence. The monsters scatter in multiple directions. Behind the HERO, the entire station is filled with airborne monsters frozen in delayed motion. HERO reaches his original position. ONLY NOW does he stop. TIME RETURNS 22–24 SECONDS The HERO lowers his hand. Black and white ink begins disappearing from the station. Color slowly starts returning to the real subway. Normal time suddenly resumes. ALL DELAYED MONSTER MOMENTUM RETURNS AT ONCE. Across the train and platform, dozens of monsters simultaneously: fall from the air, slam onto the tiled floor, crash into columns, slide across the platform, drop from train seats, tumble through train doors, and collide with each other. Create a massive synchronized impact cascade. No civilians are hit. FINAL AFTERMATH 24–25 SECONDS WIDE SHOT FIRST. The subway platform is now covered with defeated creatures. Dozens of monsters lie scattered across: the platform, around columns, inside train doors, inside the train, beside benches, and across the tiled floor. The monster horde clearly appears completely defeated. Ordinary commuters slowly look around. Several people stand completely stunned. One person still holds both hands over their mouth. Another remains sitting on the floor staring. Someone looks from the defeated monsters toward HERO. Several passengers have wide-eyed, speechless expressions. They look genuinely shocked by what just happened. Then CAMERA slowly pushes toward HERO. Medium shot. The HERO stands among the aftermath. He is slightly exhausted. Not collapsing. Just visibly tired from the enormous burst of speed. His shoulders rise and fall slightly. He takes one controlled breath. His black hair is slightly disturbed. He slowly looks directly toward CAMERA. CLOSE-UP ON HIS FACE. Then push even closer. EXTREME CLOSE-UP ON HIS BLUE EYES. A faint blue reflection remains inside the pupils. The HERO gives the camera a calm, tired, confident look. One final breath. CUT TO BLACK. ABSOLUTE CAMERA PRIORITY The camera must feel physically attached to the HERO'S high-speed movement. Do not simply observe the action from far away. CHASE HIM. RUN WITH HIM. PASS BESIDE HIM. MOVE AHEAD OF HIM. SWING AROUND HIM. ENTER THE TRAIN WITH HIM. EXIT THE TRAIN WITH HIM. Move extremely close during selected physical impacts. Then immediately accelerate with HERO again. The main visual sensation should be: THE CAMERA IS BEING PULLED THROUGH THE ENTIRE SUBWAY BY THE HERO'S IMPOSSIBLE SPEED. ABSOLUTE HERO MOTION PRIORITY HERO runs with his BODY LEANING FORWARD at maximum sprint posture. He continuously attacks WHILE RUNNING. No repeated stop-and-fight choreography. No long stationary fighting. No teleportation. No excessive blur. Show real physical running. Show real body rotation. Show real attack contact. Show continuous forward momentum. RUN → HIT → RUN → HIT → RUN → HIT. The attack chain should feel fluid, aggressive, extremely fast and uninterrupted. VISUAL MOTION CONTRAST HERO = EXTREME CONTINUOUS HIGH-SPEED MOVEMENT HERO POSTURE = FORWARD-LEANING MAXIMUM SPRINT CAMERA = DYNAMIC TAG-LOCK AT HERO SPEED MONSTERS = EXTREME SLOW MOTION PEOPLE = EXTREME SLOW MOTION BACKGROUND CHAOS = ALWAYS VISIBLE DURING THE RUN BLACK AND WHITE INK = CONTINUOUS FLOW IMPACT = FAST LOCALIZED INK EXPLOSION CREATURE FLUID = DARK GREEN CREATURE FRAGMENTS = NON-GRAPHIC SUPERNATURAL FRAGMENTS FINAL RULES Approximately 100 creatures emerge from the subway train. Opening camera rushes through the monster invasion toward HERO. HERO activates the monochrome black-and-white ink state. HERO'S blue eyes remain clearly visible. HERO maintains forward-leaning maximum sprint posture. HERO continuously attacks while running. Camera remains dynamically locked to HERO. Monsters and civilians remain dramatically slowed. Background chaos remains visible throughout the action. Black and white liquid ink continuously interacts with the environment. Impacts remain powerful but non-graphic. No human blood. No excessive gore. No teleportation. No casual upright running. No stationary fight sequences. No excessive motion blur. End with the subway returning to normal time and a close-up of HERO'S blue eyes. Maintain strong visual continuity for HERO, creatures, subway and commuters throughout the entire video.
✍️ Editor’s Notes

这条堪称全库篇幅之最,也是唯一一条把模型写成「GPT Image 2 + Seedance 2.5」组合的,基本可以断定是先用GPT Image 2把@IMG1-4这四张身份图(主角、怪物群、地铁场景、路人)配齐,再交给Seedance 2.5做动画,属于两段式生产管线。核心机制是「极端时间对比」——主角全程全速冲刺攻击,除他以外的所有怪物、路人、掉落物全部陷入极慢动作甚至悬浮定格,这个设计的聪明之处在于把「主角同时对付上百只怪物」这个理论上极难编排的多体高速混战,拆解成「只有一个物体在动、其余都是准静态背景」的简单问题,大幅降低了模型需要同时追踪的动态实体数量。台词「Ryōiki Tenkai」(领域展开)和黑白墨境的视觉设计明显是在致敬某部知名日漫的经典能力设定,但全程没有点名任何角色或作品,靠日语术语和画面风格去唤起观众的联想而不触碰版权红线。怪物体液统一设定成「DARK GREEN」而不是红色血液,也是常见的规避血腥审核的老办法。结尾专门列了一段「VISUAL MOTION CONTRAST」把核心规则浓缩成对照表重复一遍,这是因为整条词接近两万字符,担心前面的关键设定在长文本处理中被稀释,所以在结尾再补一次压缩版兜底。
