A massive golden koi fish swims through a sea of fluffy white clouds, its scales shimmering with metallic gold and orange hues. A girl in a traditional red and gold dress sits gracefully on the fish's back, holding a paper umbrella. The fish's tail creates a gentle ripple in the clouds. The lighting is warm and golden, resembling a sunset, casting a magical glow on the girl's face and the fish's scales. The scene evokes a sense of freedom and ancient mythology.
