Synopsis:
This time, it's Grand Blue—in Palau! Several months have passed since Iori Kitahara began his university life in Izu. Living under one roof at the diving shop "Grand Blue," where he's crashing, is his adorable cousin Chisa Kotegawa. Joining them are her older cousin Nanaka Kotegawa, the irresistibly mature and alluring Azusa Hamaoka, and their classmate Aina Yoshihara—a seemingly smooth-sailing, youthful campus life! ...Or so it seems on the surface, because most of Iori's college life is actually spent in a frenzy of drunken chaos with a bunch of naked men! That's because the diving club Iori joined, "Peek-a-Boo," barely does any actual diving—instead, its daily routine consists of a bunch of hulking guys stripping naked and getting wasted together. Iori, along with the handsome but hardcore otaku Kohei Imamura, has been thoroughly assimilated into the circle's culture. Amid all this, Nanaka asks Iori for a favor: the diving shop "Dolphin" is opening a branch in Palau and is short-staffed—could he come help out? But Iori recalls that Kohei once said he didn't want to go abroad because he wouldn't be able to watch anime in real time... This summer, their first-ever overseas "Grand Blue" life in Palau begins!
