Izu Diving Club
A diving club where the ocean is secondary to the bottomless supply of beer.
The Izu Diving Club, known as "Peek a Boo," is a student organization at Izu University ostensibly dedicated to scuba diving. In practice, the club is a chaotic group of buff men who spend more time drinking, partying, and stripping naked than actually diving. Despite this, the senior members sincerely love diving and take possible dangers seriously. The club's base of operations is the diving shop "Grand Blue," owned by Iori's uncle Toshio Kotegawa, where Iori stays in a room above the shop after moving to the Izu Peninsula for college.

Lore & Background
The club's culture is defined by its senior members, Shinji Tokita and Ryūjirō Kotobuki, who often get themselves and other club members drunk and naked. Tokita is a muscular, laid-back college student who loves to party, while Kotobuki can be surprisingly charismatic and works as a professional bartender part-time. Despite their rowdy behavior, both take diving seriously. Azusa Hamaoka, a senior at Ōmi Women's College, is one of the few female members in the senior circle and frequently undresses without warning. The club's antics shock new members like Iori Kitahara, a first-year Mechanical Engineering student who never learned to swim, and Kōhei Imamura, an eccentric otaku who enrolls chasing an unrealistic dream of attracting high school girls. Chisa Kotegawa, Iori's cousin and classmate, maintains a reserved demeanor and avoids the club's rowdy behavior, prioritizing her goal of becoming a dive instructor like her mother.
In Their Own Story
Iori Kitahara looks forward to his new life on the Izu Peninsula as he prepares to start college, staying in a room above his uncle's diving shop "Grand Blue." However, he is quickly shocked as he meets the local Diving Club, a group full of buff men who spend more time drinking, partying, and stripping naked than actually diving. Despite his attempts to distance himself from the group, Iori gets quickly swept up in their antics, while his cousins try to show him the wonders of diving into the ocean and sea. The club's activities often involve drunken antics, with Iori frequently finding himself drawn into their chaotic activities. Aina Yoshiwara, a shy Ōmi Women's College freshman, joins after Iori and Kōhei defend her from bullying at her former tennis club. The club's bond is forged through shared misadventures, with members demonstrating unexpected resolve when their interests are threatened.
Reader's Guide
The Izu Diving Club operates without formal ranks, centered around senior members Tokita and Kotobuki who lead the partying. Recruitment is informal: new members like Iori and Kōhei are dragged in through circumstance, while Aina joins after being defended from bullying. The club does not hold formal meetings but gathers at Grand Blue or the university. Traditions include mandatory drinking sessions that often lead to nudity, and "training dives" that are more about social bonding than actual diving. The club plays a pivotal role in the series as the social hub where characters bond, clash, and grow through shared absurdity. Notable members include Iori Kitahara, Chisa Kotegawa, Kōhei Imamura, Aina Yoshiwara, Ryūjirō Kotobuki, Shinji Tokita, and Azusa Hamaoka.
