First comes marriage, then comes an earthbound love that is out of this world!

From the day his parents named him, Nasa Yuzaki has felt connected to outer space…whether he likes it or not. His efforts to outperform the space program veer off course when an accident introduces him to Tsukasa, a mysterious girl with strange powers. Is she an alien, a moon goddess, or something else? Since she insists on marrying him, Nasa will have plenty of chances to find out!

The exam battle is heating up, along with the romantic tension between Asimo and Himari, and you know what that means—time to swerve into an unrelated flashback! See what happened long ago between Tsukasa and an apprentice monk determined to discover the key to immortality. Shake your head ruefully at Tsukasa’s chronic habit of exposing her secret to troublesome kids in need of rescue. And find out what all this has to do with Himari, who seems to know a little too much about Tsukasa. Wait a minute—this flashback isn’t unrelated at all!
