A medium shot from a straight-on angle featuring a young girl with long, sleek black hair and a youthful expression. She is wearing a traditional Japanese school swimsuit (sukumizu) made of tight, navy blue synthetic fabric that clings to her body. She is standing in a neutral pose with her hands resting naturally at her sides. The background is a minimalist, brightly lit indoor swimming pool area with white tiled walls and clear, shimmering blue water reflecting the overhead lights. The visual style is a high-quality anime illustration with clean linework, a bright and airy color palette, and soft ambient lighting that creates a fresh, clean atmosphere.
