Nonoka Komiya, Koharu Shiihara, Shione Togawa, and twins Yuzuki and Souta Mizusaka once tried to call a flying saucer to satisfy their desires. They called it quits after concluding that they had failed. Nonoka, on the other hand, unexpectedly left Kiriya City, severing the circle's tie. The gang had no idea they were successful, and the saucer has been hovering in the skies ever since, waiting to accomplish its mission.
