Plot
The story centers around high-school student Alice Sakaguchi; her seven-year-old next-door neighbor, Rin Kobayashi, who attends elementary school; and five other students who have recurring collective dreams about a group of alien scientists stationed on the Moon observing and collecting data about the Earth. Initially, when Alice learns that her classmates Jinpachi and Issei have been having common recurring dreams since middle school, she thinks nothing of it until one day she has one of these "Moon dreams" herself. Because of the nature of these dreams, the way Issei always dreams as the same person, and Jinpachi as well, now that Alice has provided a third perspective, they start to believe that people who dream as the other four scientists in their "Moon dreams" can each be found.
