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!
