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!

Nasa's students are making a horror movie! When things get a little too real, Tsukasa grabs a sword and gets busy slaying monsters. Cutting a swath of destruction is easy for our heroine--but showing her feelings for her husband? Not so much. Fortunately, the gang has plenty of ideas for ways she can show her affection, from saying those three little words to bonding over ice cream to wearing fancy underwear to bed. If only Tsukasa had the nerve to go through with any of it.
