Iori Kitahara moves to a coastal town near Tokyo to attend university, eagerly anticipating his idealized college experience. He plans to live above "Grand Blue," the scuba diving shop owned by his uncle, and hopes to blend in with normal students, find romance, and enjoy campus life. However, his dreams are immediately shattered when he walks into the shop and finds a group of boisterous, shirtless upperclassmen naked and chugging high-proof alcohol. These seniors are the core members of the university’s diving club, Peekaboo, led by senior veterans Shinji Tokita and Ryujiro Kotobuki.Though Iori initially resists joining, desperately trying to maintain his dignity, he is quickly sucked into the chaotic fold. He is joined by Kohei Imamura, a fellow freshman and former otaku who initially despises Iori due to a misunderstanding, but the two quickly bond through shared trauma and become inseparable partners in debauchery. Their initiation into the club involves endless rounds of "Oolong Tea" and "Water"—both of which are actually flammable spirits like Spirytus—igniting a cycle of forced drinking, peer pressure, and ritualistic stripping.Despite the perpetual frat-party atmosphere, the central motivation for the club revolves around actually diving and appreciating the ocean.

Chisa agrees to help Iori learn the ropes, provided he takes the training seriously. This dynamic creates a comedic tension as Iori constantly tries to balance his public humiliation and drunken exploits with genuine moments of oceanic wonder and developing academic responsibilities.Dramatic and comedic events escalate as the university campus reacts to the Peekaboo members.
