character: nakano_yotsuba. In a medium shot from a side-angle, nakano_yotsuba is positioned in the center of a vast school swimming pool. She is wearing a navy blue school swimsuit (sukumizu) and has her signature orange short hair with a green ribbon. She is actively blowing air into a super-sized beach ball, her cheeks puffed out as she grips the air valve with her hands. The beach ball is immense, featuring vibrant red, blue, and white striped patterns with a high-gloss, polished texture that is completely free of reflections. The background consists of the expansive, clear blue water of the school pool, stretching toward the distant edges of the facility. The lighting is bright and clear, evoking a sunny school day, with a clean and vibrant anime illustration style that emphasizes the saturated colors of the ball and the sparkling water.
