Core Visual: Realistic style, summer night fireworks festival, with a giant golden firework blooming in the sky in the background. An 18 or 19-year-old Japanese girl (half-body shot) turns back toward the camera in surprise and delight at the sound. Face: A classic "auspicious" (Fuxiang) round face, her skin tinted warm golden by the glow of the fireworks. Rounded eyebrows and eyes, pupils dilated with excitement, reflecting the brilliance of the fireworks. A few beads of fine sweat on her small nose. Lips slightly parted, wearing water-red lip gloss, revealing white front teeth and an innocent smile. Attire: She is wearing a light blue yukata with a white morning glory pattern, tied with a vibrant orange hanhaba obi in a magnificent Bunko knot. Her smooth black hair is pinned up with a pearl hairpin, revealing her graceful nape. Duration: 6 seconds. Audio Requirements: Grand sound effects of fireworks ascending and blooming, mixed with the cheers of the crowd, and a short, nostalgic summer festival-themed pop music intro with shamisen elements.
