ケーキ入刀が真剣勝負になる

原文プロンプト

Wan 3.0 Prompt
Create a 15-second action-comedy video with synchronized audio. Use the selected aspect ratio. Serious sword-action buildup, one spectacular stroke, an ordinary cake-cutting reveal, then A's familiar stunned face.

REFERENCES
A = the black-haired heroine in Image 1.
B = the white-haired heroine in Image 2.
Preserve their exact faces, hairstyles, costumes, accessories, proportions and original 2D anime art style. Appearance references only; new poses and background. Keep identities and character scale consistent.
A's voice timbre references Audio 1. Use its vocal identity, not its recorded words.
B has no voice reference and remains completely silent, with closed lips.
SETTING AND STYLE
Empty rooftop above Shibuya at dusk. Photorealistic rooftop and distant skyline; hand-drawn 2D anime characters with clean lines and cel shading. Match lighting and contact shadows while preserving anime faces.
A stays screen-left, B screen-right. One sturdy table stands between them toward the foreground. Maintain screen direction.
A holds one katana throughout. One plain round white-frosted cake rests on one wooden cutting board, initially on B's side of the table and visible from the first frame. One fork rests on a ceramic saucer beside B.
B uses A's serious sword technique to cut her cake.
Shot 1 (0.0-4.0 seconds): THE FINISHER
Low-angle medium-wide two-shot showing both characters, table and cake.
A plants her feet and raises the katana overhead with a two-handed grip. Bright teal energy coils around the blade. Wind lifts her hair and costume edges; one circular light ripple spreads beneath her feet. Keep her face, hands and sword clearly visible.
B looks from the raised blade to the cake and remains still during the line.
Dialogue, 0.3-1.8 seconds:
A says: "これで、おわりだ！"
Voice timbre reference Audio 1. Lip sync. Speak once in Japanese, confidently and clearly. Finish before 2.0 seconds, then close A's mouth.
Instrumental low strings and percussion build beneath a magical hum. Hard cut.
Shot 2 (4.0-10.0 seconds): THE CAKE CUT
One uninterrupted three-quarter medium shot. Show A's grip and sword, B's hands, the entire cake and tabletop together. Steady camera.
4.0-6.5 seconds: A holds the sword overhead. B pushes the cutting board's edge, sliding board and cake together to the center of the table, directly beneath the blade. The table remains fixed.
6.5-7.2 seconds: B releases the board and withdraws both hands fully to her side. Briefly hold with her hands clearly outside the blade's path.
7.2-8.5 seconds: Only after B's hands are clear, A performs exactly one powerful downward stroke. Feet planted, two-handed grip consistent. A short, brilliant teal arc follows the blade.
Show the blade physically contacting the cake before it separates.
The blade cuts through the cake's center and stops at the board. Exactly two equal semicircular halves remain upright on the board, with a narrow gap and visible fresh sponge cross-sections. The board and table stay intact.
8.5-10.0 seconds: A lifts the blade slightly to reveal the clean cut, then holds still. The teal light fades. B calmly admires the neatly divided cake.
Audio: one sharp sword whoosh, then a soft cake-slicing sound. Stop the dramatic music and magical hum abruptly when the two halves are revealed. No dialogue. Hard cut.
Shot 3 (10.0-12.0 seconds): JUST DESSERT
Medium two-shot, A left and B right. Keep both cake halves visible.
B casually picks up the fork from the saucer. A small ceramic clink. She looks at the cake with her usual calm expression and closed lips.
A looks from the cake to B's fork. Her confidence disappears. Her sword points downward beside her body.
No dialogue. Fork clink and faint rooftop ambience only. Hard cut.
Shot 4 (12.0-15.0 seconds): THE FAMILIAR FACE
Close-up of A, preserving Image 1's facial design.
Eyes widen, pupils become small, eyebrows rise. Lips part slightly once, then remain still. Her familiar stunned, uncomprehending expression.
A short, controlled push-in. Hold her face for the final full second, with only tiny shoulder trembling.
No dialogue or vocal reaction. End directly on A.

AUDIO CONTROL
Exactly one spoken sentence: A's line in Shot 1. After 2.0 seconds, both characters produce zero vocal sound.
Keep the specified instrumental music, sword effects, fork clink and ambient wind.
No improvised speech, narration, inner monologue, gasps, grunts, screams, laughter, vocal breaths, choir or vocal samples. Never replay Audio 1's recorded words.
NEGATIVE PROMPT
Extra characters, duplicate bodies, mixed identities, costume changes, realistic character faces, 3D game-CG, chibi, extra limbs or fingers, fused hands, unstable props, repeated swings, detached energy beams, crushed or exploding cake, extra cake pieces, broken table, building destruction, injury, wedding staging, subtitles, readable text, logos, watermarks, HUD, end card, canned laughter, comedy sting, excessive camera shake.
