Grand Blue Dreaming

After a cutthroat battle with Kohei Imamura, a handsome otaku from school, Iori ends up joining the Peek-a-Boo diving club. Iori arrives home worn out from the day, but perks up when he hears about a party with a womens college. However, his cousin Nanaka wont allow him to stay out three nights in a row, so Iori tries to show her hes an independent man to get her to let him go.

The Izu Spring Festival has begun! The members of Peek-a-Boo run an okonomiyaki stall with Iori, Kohei, Chisa, and Azusa helping out. Iori finds himself in a complicated situation when a misunderstanding with Azusa occurs and a rivalry with the tennis club Tinkerbell begins. When Chisa gets nervous and freezes up during the womens beauty pageant, Iori and Kohei think of a plan to cheer her on.

Inori and Kohei get through their exams by cheating. Meanwhile, PaB throws a welcome party for Aina, their new member. Aina was looking forward to getting a new start to college life, but discovers that no one in the club is normal! Nevertheless, the club members are serious about diving and have the new members learn basic hand signals and dive in pairs. However, Iori gets paired up with Chisa.

The members of the diving team start working part-time jobs to pay for their trip to Okinawa. However, Iori and Kohei end up spending all their earnings on drinking. Meanwhile, Kotobuki is working hard as a bartender, and his boss lets Iori and Kohei try it out too. However, these two idiots dont know how to make cocktails, and end up creating some dangerous new drinks!

The Peek-a-Boo members arrive in Okinawa! After checking out their gorgeous vacation home, the group decides to head to the beach. In order to make sure the guys dont try to get naked, they decide to go to a popular beach with lots of visitors, where they have some wild fun on a banana boat. However, Iori loses their banana boat contest and ends up having to sleep in Nanaka and Azusas room!

For the last half of their trip, the Peek-A-Boo members arrive in Miyakojima. Everyone goes for a serious dive into the majestic sea with the exception of Iori, who couldnt obtain his license. Everything is magical with the stunning coral reef, colorful fishes and sea turtles, until the members engage in PaB-style Otori (a drinking custom of Miyakojima), which turns things into a living hell...

Shioris here and on a mission! How will Iori handle this situation?
