Viz Media Fly Me to the Moon, Vol. 19

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!Nasa and Tsukasa venture into the mountains to visit the house where Tsukasa once lived in seclusion. There, they hope to find clues to unlock the data left for them by Tokiko-data that could end Tsukasa's long quest. Failing that, at least they can pore over her old hoard of vintage manga. And if that's not enough fan service for you, Nasa's students explore the wilderness and wind up skinny-dipping!
