After a cutthroat battle with Kohei Imamura, Iori ends up joining the Peek-a-Boo diving club.

Iori and Kohei don wetsuits and head to the sea! Although Iori used to be afraid of the water, he starts becoming more interested. But diving equipment is expensive! Tokita and Kotobuki decide to hold a men's beauty pageant for the Izu Spring Festival in May. The guys want to avoid being paraded around on stage, so they try to get Chisa to participate in a women's beauty pageant.

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.
