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 and Tsukasa may be temporarily homeless, but life isn't all bad for the newlyweds. Staying at the neighborhood public bath, they earn their keep by helping out and still have time for cooking parties and retro video games. Nasa finally manages to plan a simple date. Tsukasa finally gets a cell phone. And the artist finally gives in to the temptation to draw Tsukasa in a maid uniform.
