High-resolution, deformed anime-style watercolor illustration with a dynamic angle, in a wide format. The scene features a young girl android riding a sci-fi mechanical vehicle resembling a flying fish, now predominantly in shades of red, in a post-apocalyptic city during late autumn. The vehicle has a narrow, elongated seat, indented on the top, and is about 50cm wide. A prominent white envelope (✉) symbol is painted on the vehicle, symbolizing its purpose for delivering messages. At the rear of the vehicle, there's visible luggage. The android is in a forward-leaning position, straddling the red vehicle with the envelope symbol. The vehicle emits a faint blue glow from its underside. It's afternoon, with buildings surrounding them. The android is wearing a rugged, post-apocalyptic version of a school uniform and long coat, a scarf, and her hair is back-length black with a hint of blue.
