Iori Kitahara’s college life in Izu has settled into a familiar rhythm: living above the Grand Blue diving shop, spending time with his cousin Chisa, and getting dragged into the drinking and half-naked chaos of the Peek a Boo diving club. Then Nanaka asks him to help at a new branch of the Dolphin diving shop in Palau, where the staff are short-handed. The offer promises clear water, serious diving, and the group’s first adventure abroad. It also creates an immediate problem: Kohei has already insisted he will not leave Japan if it means missing his anime broadcasts. Getting the club overseas may be as difficult as anything waiting beneath the surface. Once the trip begins, Iori and his friends trade their usual campus disasters for Palau, where a new ocean gives them fresh opportunities to dive—and to turn every plan into another ridiculous mess.
