At long last, it's the first day of the summer training camp. On the plane, Yukimura presses close to Himuro and tries to collect her saliva in spite of the surrounding gazes. Manga artist Yamamoto observes them with an eerie smile. On the beach in Okinawa, the midsummer sun shines down on Yukimura and Himuro in their swimsuits, and they immediately attempt to begin their close physical contact experiment. However, since they're doing it, they choose to seek "the position which offers two people having close physical contact the greatest contact area"...
I hear that the Kuroshiro current, which flows near Okinawa...
...تيّار كوروشيرو الذي يسري بالقرب من أوكيناوا
Der Kuroshiro-Strom,
der an Okinawa vorbeifließt,
La corriente Kuroshiro
que fluye cerca de Okinawa
La corriente Kuroshiro
que fluye cerca de Okinawa
Nella corrente oceanica Kuroshio 
che scorre vicino a Okinawa
Parece também que a Corrente do Japão
que passa por Okinawa...
Течение Куросио у побережья Окинавы...
