No one besides Saku has joined the astronomy club, so recruiting tactics are still going on. Hime Makita from Saku's class is annoyed that Mihoshi and other astronomy members come to their class so often when she would rather spend some time alone with Saku. Hime met him on the bus to take the entrance exam of the school they now attend, and was thrilled to see they were put in the same class. After Hime finds out that Saku and Mihoshi are not dating, Hime joins the astronomy club, which finally becomes officially recognized. Another day, the astronomy club members go stargazing far from the city's lights.
Saku Oyagi returns to his old hometown in order to start school at Soei High School. On the first day, he runs into an old childhood friend: a second year named Mihoshi Akeno. As children, the two used to play together, with Mihoshi, or Mii-chan, being extremely fond of astronomy. After convincing Saku to join the school's astronomy club, another girl, Hime Makita, joins the club in hopes of winning over Saku. This is the story of the 6 club members of the Soei High School Astronomy Club as they soar through their lives, each maturing and changing their outlooks on life.
