[SHOT 1 — 00:00-00:07 — HIYORI'S SUMMER]
Late afternoon on a narrow seaside festival path bordered by tall sunflowers and a few red paper lanterns. HIYORI appears completely alone in the foreground, wearing the exact pale-yellow yukata and cream obi from @Image 1. Begin with a warm medium-wide front three-quarter view, keeping most of her face visible rather than showing a full side profile. Use one gentle lateral tracking move as she strolls beside the sunflowers. A sea breeze softly moves the ends of her long golden hair, sleeves, and golden tail. She slows, turns slightly more toward the sunlight and camera, and gives a tender, reassuring smile. Golden light and visible blue, violet, and green reflections from the summer sky and leaves spread through her golden-core eyes. She lifts a round paper fan close to the lens, creating a natural full-frame occlusion transition. Audio: cicadas, a soft coastal breeze, distant festival ambience, and fabric rustle. No dialogue.

[SHOT 2 — 00:07-00:14 — YUKINE'S SUMMER]
The fan clears to reveal twilight at a small wind-chime stall in the same seaside festival district. YUKINE appears completely alone in the foreground, wearing the exact pale-blue patterned yukata and navy obi from @Image 2. Use a stable medium shot with one very slow dolly-in. She calmly reaches with one hand and lightly touches a clear blue glass wind chime. The breeze rings it once and gently moves her long white hair, sleeves, and white tail. She watches the chime, then shows a small, warm smile that reveals her quiet kindness without becoming exaggerated. Keep her deep dark-brown skin and both vertically two-tone blue-over-yellow eyes clearly visible. End on a bright reflection passing across the glass wind chime and filling the frame. Audio: one clear glass chime, evening cicadas, soft breeze, and distant festival footsteps. No dialogue.

[SHOT 3 — 00:14-00:21 — AOI'S SUMMER]
The blue glass reflection becomes the cold blue glass of a ramune bottle at a brightly lit festival drink stall after nightfall. AOI appears completely alone in the foreground, wearing the exact white-and-pale-blue wave-pattern yukata and dark-blue obi from @Image 3. Use an energetic medium close-up with one short, smooth sideways track. Condensation beads on the bottle. AOI raises it, takes one small sip, hears the marble rattle, and reacts with a delighted open smile. Her curiosity and expressive personality are clear, but her motion remains physically natural. Keep both eyes open and prominent: viewer-left yellow, viewer-right blue, with a white cross-shaped highlight in each eye. Preserve the single white bang streak, the single viewer-right white braid, the single viewer-left black X hairpin, and the white tip of her blue tail. She lifts the blue bottle toward the night sky; the bottle fills the lens and its blue highlight becomes a blue firework. Audio: ramune marble rattle, one small sip, festival ambience, and the first distant firework launch. No dialogue.

[SHOT 4 — 00:21-00:30 — THE THREE TOGETHER]
The blue firework blooms above a quiet seaside waterfront beside the same festival. Reveal exactly three foreground characters and no other foreground people in a stable frontal medium-wide shot. On the same depth plane: HIYORI left in @Image 1's yukata, shorter AOI center in @Image 3's yukata, YUKINE right in @Image 2's yukata. Keep this order. Use a gentle forward dolly only; do not orbit or cross the camera axis.

Hiyori has a distinctly high-pitched, soft, 
bell-like feminine voice in a light soprano register, 
with delicate crystalline clarity. Her delivery is gentle and smooth, 
with tender, softly musical intonation and a clear, soothing brightness.
