Episode 2 Story
Although a trip to Palau has been decided, Iori's passport is left at his family home. He asked his younger sister, Shiori, to mail it to him, but she flatly refused for some reason. Left with no choice, Iori decided to take Chisa and Kohei with him for a brief visit back home. However, even when they met face-to-face, Shiori still rejected the request, saying, "Absolutely not." Seeing no other option, they form a plan to infiltrate Shiori's room, but at the inn, they spot the suspicious Germans they met on the train on their way there...

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!
