A medium shot from a side-angle view depicts a young girl riding atop a colossal whale as it glides through a vast, open sky.
The girl, appearing to be in her early teens with a joyful expression, is perched comfortably on the whale's back. She wears a simple, light-colored summer dress that flutters in the wind, and her small hands are gripping the whale's skin for balance. The whale is immense and majestic, with a smooth, deep-blue skin texture and a gentle gaze, soaring effortlessly through the air.
The background is a brilliant, clear blue sky filled with soft, drifting white clouds. A vibrant, multi-colored rainbow arcs gracefully across the horizon, spanning the width of the scene and adding a sense of wonder.
The visual style is a high-quality anime illustration with a bright, saturated color palette. The lighting is radiant and sunny, creating a hopeful and serene atmosphere with a soft glow illuminating the characters and the surrounding clouds.
