A full body shot from a side angle depicts a happy girl swimming through a vibrant coral reef, looking back over her shoulder toward the viewer. She has dark blue hair styled into braided twintails with a playful ahoge wagging atop her head and strands falling between her eyes, adorned with delicate hair ornaments. Her eyes are heterochromatic, shimmering in gold and white. She wears an ornate mermaid cosplay outfit with iridescent scales. Her arms are gracefully extended as she glides through the water, her hands gently pushing against the current. The background is a lush underwater landscape filled with colorful coral reefs, scattered sea ground, and schools of small fish, with translucent water bubbles floating around. Beams of bright sun rays pierce through the water's surface from above. The visual style is inspired by 90s shoujo art, featuring painterly anime coloring, sketchy linework, and soft blended shading contrasted by dramatic, high-contrast lighting.
