Episode 1 Story
Summer is drawing to a close, and the season of retirement is fast approaching for the third-year members of Pab. In the midst of this, everyone decides to pitch ideas to do everything they left undone this summer. "I want to see everyone in yukatas," "I want to make takoyaki," "I want to throw a memorable drinking party." However, there was no way these events, which beautifully color the youth of their college life, would end peacefully. A note written at the edge of the memo reads, "※All done Pab-style." The extraordinary Pab-style summer festival begins with everyone stripping!

This time, it's Grand Blue Dreaming in Palau!
It has been a few months since Iori Kitahara began his university life in Izu—. At "Grand Blue," the diving shop where he is staying, he lives under the same roof as his cute cousin, Chisa Kotegawa. Joining them are his older cousin Nanaka Kotegawa, the irresistibly mature and sexy Azusa Hamaoka, and his classmate Aina Yoshiwara. On the surface, he was enjoying a smooth-sailing, youthful campus life!
...But that's only one side of the story. In reality, the vast majority of his university life is a frantic frenzy surrounded by stark-naked guys! This is because "Peek a Boo," the diving club Iori joined, treats diving as a sideshow, making a daily routine out of buff men stripping completely naked to down drinks and cause a ruckus. Alongside Kohei Imamura—a good-looking guy who happens to be a hardcore otaku—Iori has become thoroughly corrupted by the club.
Amidst all this, Nanaka asks Iori for a favor: the diving shop "Dolphin" has opened a branch in Palau, and since they are short-handed, she wants him to come over and help out. However, Iori remembers that Kohei strictly refused to go abroad because he wouldn't be able to watch his anime in real-time...
This summer, their very first overseas "Grand Blue" life kicks off in Palau!
