制服少女と虹の空

anime illustration, A medium rear-view shot shows a teenage girl with short, silver-white hair tied in a short ponytail standing still on a wet city rooftop, her back to the viewer as she gazes up at a rainbow arching across the post-rain sky. She wears a drenched, semi-translucent navy-blue sailor uniform with a white collar and red ribbon, the fabric clinging to her frame with visible folds and sheen. Her arms rest naturally at her sides, fingers slightly curled. The urban background consists of tall concrete buildings lining the skyline, asphalt streets below dotted with reflective puddles that mirror the rainbow. Soft overcast daylight illuminates the scene with faint sunbeams filtering through dissipating clouds, water droplets on surfaces catching glints of light. The tranquil atmosphere features a muted blue and gray palette accented by the vivid, multi-colored arc of the rainbow both above and reflected in the puddles.
