杉林夜色中的雷劍決鬥

Start exactly on the opening frame. FORMAT: 16:9 horizontal, 30 seconds, 10 shots, hard cuts on the timestamps. STYLE: modern theatrical anime, cel-shaded, clean line art, flat vibrant colour with deep saturated darks, painterly background art; no photographic texture overlay. STRONG CHIAROSCURO, extreme contrast throughout: near-black cedar forest and night sky against small hot lantern orange, and against the gold-violet of the lightning; hard rim light on every silhouette; never flat even lighting. Dense layered depth in every shot: wet reflective stone in the foreground, the fight in the midground, the receding double row of stone lanterns and black cedar trunks behind. THE WOMAN: mid-twenties, tall and long-limbed with mature adult proportions, straight-backed and composed, a calm hard gaze; sharp cool grey eyes with upswept outer corners; jet-black hair, no gradient, in a high ponytail with two loose strands at the temples; deep indigo Japanese short-jacket and hakama, a plain dark leather chest guard, white wrapped bracers; a plain charcoal short haori with a ragged torn hem and no pattern of any kind; a slim straight sword, cold silver blade with no colour gradient, plain square iron guard. Her blade is ALREADY DRAWN and in her right hand from the first frame; it is sheathed only once, at the very end. Referred to as "the woman". THE DEMON: not humanoid. A shifting mass of liquid blackness that holds no fixed shape - it pours, bulges and re-forms; from inside it, long thin claws and clusters of small red glowing eyes push out and withdraw. It has no face and no body plan. It never becomes a person. SCENE: a long stone stairway at night in a cedar forest after rain, stone lanterns down both sides, mist in the lantern beams, wet steps mirroring the flames. RULES - action: each shot is one continuous camera take, no jump to a new position inside a shot. Every strike runs visible target then body entry then strike motion then clear contact then immediate body reaction then balance change then next action; no reaction before contact; no effects in place of real body motion. Full speed throughout - no slow motion, no speed ramps, no freeze frames. Effects allowed: SPEED LINES, SMEAR FRAME, IMPACT BURST, SHOCKWAVE RING - sparingly, and the heaviest only on the finishing blow. Lightning is gold-violet, thin and forked, and it lights the whole forest for the instant it exists. [1. Found, 0-4s] The camera holds behind and left of her, then rises and pushes slowly up the stairway past her shoulder. She stands with the drawn blade lowered at her side, looking up into the dark. More red points open above her - three, then eight, then too many to count. One thread of gold-violet runs the length of the silver blade and dies. She turns her head a few degrees further toward them. The woman, low and level: "……見つけた。" HARD CUT. [2. First exchange, 4-7.5s] Wide side-on shot across the steps. The black mass pours down the stairway and a long claw comes down at her; she steps off the line and the claw splits the stone where she stood, chips flying. She is already turning into the gap. HARD CUT. [3. Her answer, 7.5-11s] Low tracking shot rising with her. She cuts upward backhand through the mass; gold-violet arcs tear along the wound and the blackness recoils up the steps, shedding eyes that wink out as they fall. HARD CUT. [4. Three at once, 11-14.5s] Medium shot, the camera circling her. Three thin claws stab in from three sides; she parries all three, one two three, sparks and thin lightning at every contact, her feet sliding back a hand's width each time. HARD CUT. [5. Struck down, 14.5-18s] The fourth blow catches her and throws her; she hits a stone lantern back-first and it bursts, scattering orange fire across the wet steps. She comes up on one knee, still holding the blade, and her gaze goes colder; gold-violet begins to leak from her shoulders and forearms. Behind her the mass swells into a wall and every eye in it opens at once. HARD CUT. [6. Gathering, 18-19.5s] Tight close-up. She drops low with the blade held back and low behind her, both hands on the hilt; lightning pours down her arms and floods the whole length of the steel until it is a bar of gold-violet, and the stone under her boots cracks and lifts. The woman, shouting: "雷牙——八重！" HARD CUT. [7. The strike, 19.5-21s] The frame holds the empty stairway for a beat - she is no longer where she was. A single gold-violet diagonal tears across the whole screen, SPEED LINES and one SMEAR FRAME, the forest lit white-gold for that instant. HARD CUT. [8. Eight fangs, 21-23s] Eight afterimages of her enter the black mass from eight directions at once, each one a clean stroke; every cut line bursts gold-violet, IMPACT BURST on each, a SHOCKWAVE RING going out across the treetops. HARD CUT. [9. Undone, 23-27s] The mass is lit from inside by the eight burning lines, holds one moment, then comes apart into ash that lifts upward through the lantern light. She lands with her back to the camera at the top of the steps and slides the sword home for the first time; the guard closes with one hard click. HARD CUT. [10. After, 27-30s] The camera pulls back and cranes up into a high wide of the whole stairway. One by one the stone lanterns light again down both sides, a double line of small warm flames running away downhill, ash still drifting up through them. She stands alone halfway down the frame, small. Hold one second. AUDIO: mist and dripping cedar, a single distant temple bell / then stone splitting, cloth snapping, blade on claw, her breath and boots on wet stone, lantern glass bursting / then the deep crack and roll of lightning on the finishing blow, ash hissing, and one hard click as the guard closes / at the end only rain-drip and the bell again. Her two lines in Japanese, low and hard; the demon has no voice, only a wet shifting sound. No BGM, no music, no score, no instruments, no humming, no singing, no narration, no subtitles. CONSISTENCY: the woman's face, facial proportions, adult build, skin tone, jet-black high ponytail with the two temple strands, cool grey upswept eyes, indigo jacket and hakama, leather chest guard, white bracers, plain charcoal torn-hem haori and the plain silver blade identical in every shot; strictly no random character changes; never change the visual style. AVOID: subtitles, watermarks, logos, on-screen text; photorealism, 3D game CG, plastic skin; identity drift; the demon ever taking human shape or growing a face; any patterned haori, checkered or flame motifs, earrings, or a colour-gradient blade; flat washed-out lighting, low contrast; slow motion, speed ramps, freeze frames; reactions landing before contact; effects standing in for body motion. Modern theatrical anime, cel-shaded, high contrast chiaroscuro, expressive facial animation, dense painterly background art, character design consistent throughout.
