A medium shot from a slightly low angle depicts a young girl with flowing light blue hair riding on the back of a large shark, gliding across the ocean surface. The girl wears a simple white summer sundress that flutters in the wind, her expression one of pure joy and excitement as she grips the shark's dorsal fin with both hands. The shark's skin has a sleek, metallic grey texture, cutting through the deep turquoise sea. Dramatic white water splashes erupt around them, with individual droplets frozen in mid-air. The waves around the shark glow with a luminous, iridescent light, creating shimmering trails of neon blue and silver. The scene is set under a scorching midsummer sun, with a clear, brilliant blue sky and a distant horizon where the sea meets the sky. The lighting is intense and bright, with high-contrast highlights on the water's surface and a vibrant, saturated color palette that evokes a refreshing yet energetic summer mood. The visual style is a high-quality anime illustration with crisp lines and luminous environmental effects.
