Itsuki, Nayuta, and Miyako have a hard time dealing with the cold and head down to Okinawa. The next day, they visit a remote island so Itsuki can do some research and Nayuta decides to flail around naked in the water. Miyako is awed by what she's seeing and eventually jumps into the water naked, as well. Two days later, Itsuki is invited by his illustrator to go to Hokkaido, where they try various local cuisines. However, Itsuki finds out that Setsuna had been ignoring a deadline...
I wonder if I'll ever be able to go 
to a world that sparkles like that...
Ob ich es jemals erleben werde,
dass auch meine Welt so strahlt …?
Me pregunto si podría ir
a un mundo así de brillante…
Me pregunto si podría ir
a un mundo así de brillante…
Est-ce que moi aussi,
Chissà se anch'io un giorno riuscirò
a vivere in un mondo luminoso come il suo...
Me pergunto se um dia conseguirei 
ir para um mundo cintilante assim...
Интересно, смогу ли когда-нибудь
и я засиять столь ярко?
