character: yuuka_(blue_archive). In a medium shot illustration, yuuka_(blue_archive) is framed from the chest up, emerging from the water of an indoor swimming pool. She is positioned centrally, looking upward at the viewer with a coy, upturned gaze. She is a teenage girl with long, straight, light purple hair and purple eyes. She wears a dark blue one-piece swimsuit. Her arms are resting on the pool edge, with her hands gripping the surface. Her expression is soft and inviting, with her mouth slightly parted. The background shows the interior of a modern swimming facility, featuring white tiled walls, a ceiling with bright fluorescent lighting, and the light blue pool water. Gentle ripples and small bubbles surround her in the water. The overall style is anime-inspired, with smooth shading, crisp lines, and a clean, vibrant color palette.
