FLY ME TO THE MOON GN VOL 19

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 fanservice-y enough for you, Nasa's students take advantage of the trip to go skinny-dipping.
