A medium shot from a rear view captures a young girl and her older sister standing close together on a riverbank at night, watching a fireworks display. The older sister, with high-density hair strands catching luminescent gradients, wears a deep indigo yukata with intricate white floral patterns and a neatly tied woven obi. Beside her, the younger girl wears a pale-pink yukata with delicate pastel motifs, her small hands clutching a paper fan. They are positioned at the edge of a dark river that reflects the brilliant bursts of gold,magenta,emerald, and violet fireworks exploding in the sky above. The scene is illuminated by warm, flickering light casting glossy tones on their skin and shoulders, with fine sparks drifting down like glowing embers. The visual style is a hyper-detailed anime-style realistic 3D rendering with hyper-saturated colors, extreme three-dimensionality, and ultra-sharp textures on the fabric, creating a magical and wonder-filled atmosphere.
