character: mizumiya_su, A medium shot captures Mizumiya Su standing in the narrow aisle of a nostalgic Showa-era snack shop, looking back over her shoulder with a gentle, warm smile. She has long blue hair styled in twin braids with pale pink and purple gradient tips, a small ahoge, large clear blue eyes, and a cute, youthful face. Her translucent white skin glows under the warm lighting. She wears a white oversized jacket (hoodie) over a turquoise blue top, black shorts, white and blue platform sneakers, and blue leg warmers, holding a small shopping basket in her right hand while her left hand rests lightly on the handle. The wooden interior is densely packed with floor-to-ceiling shelves filled with glass bottles of colorful snacks, Ramune bottles, Coca Sigaretto, and other retro toys. An old cash register and retro posters adorn the walls. Cinematic lighting with volumetric rays of golden twilight streams through the entrance, reflecting beautifully off the glass bottles. The atmosphere is nostalgic and quiet, resembling a secret base, with Studio Ghibli-like warmth and Makoto Shinkai-style lighting, rendered with extreme detail, high quality, and a 35mm film aesthetic.
