Grand Blue Dreaming

Iori heads off to college and decides to live at his uncle's dive shop; during his first day in college, Iori gets dragged into the diving club's crazy antics.

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 women's college.

The Izu Spring Festival has begun, and the group run an okonomiyaki stall with Iori, Kohei, Chisa, and Azusa helping out. Iori has a misunderstanding with Azusa, and Chisa gets nervous and freezes up during the women's beauty pageant.

Iori and the others want to go diving at a beautiful location after seeing an article on Miyakojima. However, Tokita and Kotobuki organise a tennis doubles match and say it is to build trust, but it is really to take away the cash prize.

The diving team start part-time jobs to pay for their trip but Iori and Kohei spend their money on drinking. Meanwhile, Kotobuki is working hard as a bartender, and his boss lets Iori and Kohei try it out too with disastrous consequences.

Iori tries to setup another mixer for his friends, and wants to ask Chisa to introduce her friends so they can all play truth or dare. Nanaka and Azusa also get involved. Meanwhile, Iori doesn't have enough money for their trip.
