Izaka Shou (played by Hayato Ichihara), Motohiko (played by Yosuke Handle), Tamashiro Tetsuo (played by Yuta Hiraoka), and Minatogawa Yu (played by Mao Inoue) are seniors at an ordinary high school in Okinawa. For them, the sky and the sea are incredibly commonplace; they have lost interest in everything and are enduring each dull day. One day, while working at the aquarium, Shou meets a sexy older woman named Nakamura Nami (played by Ayumi Ito).
