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...
This is my new project after going to 
Okinawa and being awed by a whale shark.
Das ist mein neues Werk, zu dem mich

Es mi nuevo proyecto tras ir a Okinawa
y ver un tiburón ballena.

y ver un tiburón ballena.
C’est mon nouveau projet, inspiré
par les requins-baleines d’Okinawa,

a Okinawa dopo aver visto uno squalo balena.
Esse é o projeto novo que comecei depois de ir em
 Okinawa e me espantar com um tubarão-baleia.
Я так впечатлился китовыми акулами на Окинаве,
что написал новую работу!
