A full body shot from a side angle depicts a high school girl performing a vertical Y-balance split in the center of a spacious school gymnasium. The girl has her hair tied in a high, swinging ponytail and wears a tight-fitting, high-cut leotard in a combination of green and white colors. She maintains a focused yet serene expression, balancing perfectly on one leg while the other is extended straight upward toward the ceiling, her arms gracefully extended to the sides for stability, hands open and fingers tapered. The background is a traditional Japanese gymnasium with polished wooden floorboards reflecting the overhead lights, white walls, and distant sports equipment like volleyball nets and mats arranged along the perimeter. The scene is illuminated by bright, natural light streaming through high windows, creating a clean, airy atmosphere with a vivid color palette and a crisp, high-quality anime illustration style.
