Nao, an 8th grader, is one of the only two members of a Digital Camera Club, where she also serves as the manager. It's a mystery that she shoots nothing else but the skies and clouds.

And there's Jun, who helps Nao and Miki look for a cat that can fly. Then, there's Yukio, who is the widow of Taiki's deceased brother.
