A medium shot from a front-facing angle features a plain, shy teenage girl standing in an indoor swimming pool area. She has an okappa-style bob cut of dark hair and wears thick black-rimmed glasses that frame her timid expression. She is dressed in a standard navy blue school swimsuit (school mizugi) that fits her slender, flat-chested physique. Her posture is hesitant and embarrassed, with her shoulders hunched and her hands clutching the hem of her swimsuit or fidgeting nervously by her sides.
The background consists of the tiled walls and shimmering blue water of a school pool, with soft reflections of overhead fluorescent lighting dancing on the surface. The atmosphere is quiet and slightly awkward, emphasizing her social anxiety and modest presence. The visual style is a high-quality anime illustration with clean line art, soft shading on the skin, and a muted color palette to reflect her unassuming personality.
