Episode 8 Story
Summer vacation has ended. Gathering at the university after a long time, the guys discuss their summer experiences, but their stories are full of grand claims covered in vanity and bravado. To expose the truth, a viciously modified lie detector appears, dealing a deadly punishment to anyone who lies. A fierce verbal battle unfolds with their own balls on the line! Then, the men move to the next stage. One thing leads to another, and Iori is threatened into organizing a group date with women, including Nanaka. The lie detector makes an appearance here as well.

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!
