integrated_multimodal_description: Create a complete 15-second Japanese folk-tale explainer in a vertical 9:16 composition, telling the story of Momotaro. Use friendly 2D flat-vector picture-book illustration: thick, even, near-black outlines of consistent weight, flat solid color fills, no shading, simple dot eyes and small curved mouths, restrained cutout animation, and a light paper grain over the flat color fields. Use a compact palette of warm off-white, soft peach pink, deep indigo blue, vermilion red and golden yellow, with near-black outlines. Background color changes mark the chapters of the story. No photorealism, no 3D rendering, no gradients, no drop shadows, no browser interface, no screen-recording artifacts, and no player controls.
[Shot 1] Begin on a warm off-white background. An old man in a brown work coat carrying a bundle of firewood walks off toward the frame-right edge while an old woman in a blue apron carrying a round wooden washing tub walks off toward the frame-left edge, the two of them separating in one smooth movement. Then the Japanese caption "むかしむかし" appears at the top of the frame, sliding in gently word by word.
[Shot 2] At 00:01.500, a soft peach-pink field wipes across the frame. A large peach with a simple leaf drifts down a stylised river of curved white lines from the top of the frame toward the bottom. The old woman pops in at the lower edge and raises both hands in surprise.
[Shot 3] At 00:03.000, staying on peach pink, the peach splits cleanly into two halves and a small boy in a red vest sits up between them with his arms raised. The name "桃太郎" assembles in large near-black type in two stages beside him.
[Shot 4] At 00:04.500, a warm off-white field wipes in. The boy grows taller in three clear steps, becoming a young man with a headband. The old man and the old woman pop in on either side of him and smile.
[Shot 5] At 00:06.000, staying on warm off-white, the old woman holds out a small cloth bundle of millet dumplings and the young man takes it in both hands. He then raises a simple banner on a pole and starts walking toward frame-right.
[Shot 6] At 00:07.500, staying on warm off-white, a white dog, a brown monkey and a green pheasant pop into the frame one at a time, each with a small bounce. The four of them then line up in a neat row facing frame-right.
[Shot 7] At 00:09.000, a deep indigo-blue field wipes across the frame. A small wooden boat carrying the four of them rides over rows of simple curved waves from frame-left toward frame-right. The dark silhouette of an island with a gate then rises into view at the far right.
[Shot 8] At 00:10.500, a vermilion-red field wipes across the frame. A large red ogre with two horns, a spiked club and a tiger-skin loincloth plants himself in front of a heavy gate, filling the centre of the frame. The caption "鬼ヶ島" appears above him in near-black type.
[Shot 9] At 00:12.000, staying on vermilion red, the young man and his three animal companions leap in together from frame-left and the ogre drops backwards onto the ground with his club falling from his hand. A golden-yellow field then wipes across the frame from the bottom.
[Shot 10] At 00:13.500, on golden yellow, the four of them pull a small cart stacked with treasure chests and coins from frame-left to frame-right, the ogre bowing behind them. The background settles to warm off-white and the closing caption "めでたし めでたし" appears in large near-black type, assembling in two stages and holding cleanly until exactly 15.000 seconds.
overall_soundscape: Soft water plops and a gentle stream accompany the peach as it drifts, and the peach opens with a light crisp pop. Paper-like pops mark each caption and each animal as it enters. Short restrained whooshes carry the color-field wipes, with wooden creaks and lapping waves under the boat. A single deep drum hit lands as the ogre plants himself, followed by a soft thud when he falls and bright chimes as the treasure cart rolls past. No dialogue.
non_diegetic_music: Generate an original 15-second Japanese folk-tale jingle using shinobue bamboo flute, plucked shamisen, light taiko drums and small hand bells at a moderate walking tempo. Begin sparse and calm over the off-white opening, brighten as the peach appears, drop low and sparse over the indigo sea, turn urgent with heavier taiko over the red ogre section, resolve into a warm bright melody on the golden treasure section, and finish with one clean final chord at exactly 15.000 seconds.
