A wide-angle, eye-level medium shot depicts a large group of long, black-haired girls swimming joyfully in a sparkling turquoise sea. The girls, varying in age and expression, are scattered across the water's surface, some splashing each other with their palms while others float or swim forward with bright, beaming smiles and laughter. Each girl is dressed in a traditional navy blue old-school one-piece swimsuit, featuring a modest cut and crisp white piping. The crystal-clear ocean water creates gentle white foam and ripples around their bodies, with sunlight refracting through the waves. The background consists of a vast, shimmering horizon under a clear, brilliant blue sky with a few fluffy white clouds. The visual style is a high-quality anime illustration characterized by a vibrant and saturated color palette, bright natural sunlight, and a refreshing, energetic atmosphere of summer fun.
