A medium shot from a side angle depicts a cheerful girl with long blonde hair fading into purple tips, styled in thick braids, riding on the back of a dolphin in the middle of the sea during twilight. The girl is wearing a futuristic cyberpunk-style bikini made of metallic fabrics and glowing neon circuits, gripping the dolphin's smooth skin with her hands as she laughs joyfully, leaning forward. She is positioned centrally, gliding across the water's surface. The environment features a vast, calm ocean reflecting the deep oranges and purples of a sunset sky, with gentle ripples and splashes of water around the dolphin. The visual style is a high-quality anime illustration with a vibrant, warm color palette, cinematic lighting from the setting sun, and a dreamy, energetic atmosphere.
