Sophia University Diving Club

Lore & Background

The dynamic between the club's serious-minded members, like Chisa, and its chaos agents creates a unique social ecosystem where diving skills are often secondary to drinking endurance. The apartment itself has become a legendary location within the university, known for its smell of stale beer and the constant noise of laughter or shouting. It is here that Iori Kitahara's journey from a reserved freshman to a fully integrated member of this bizarre family begins, marking his transition into the wild world of Sophia University.

In Their Own Story

The afternoon sun filtered through the dusty blinds of the second-floor apartment, illuminating floating dust motes and empty beer cans scattered across the tatami mats. Ginji sat cross-legged in the center, holding a bottle of sake with the reverence of a priest, while Kohei attempted to explain buoyancy control using a half-eaten bowl of fried chicken as a prop. "Listen," Iori groaned, rubbing his temples as another freshman stumbled through the door, eyes wide and hopeful for a diving lesson. Instead, they were handed a bottle of beer before they could even take off their shoes. The ocean was far away; right now, the only tide that mattered was the one rising in their stomachs.

Reader's Guide

The hierarchy is loosely structured around Ginji's absolute authority as president, though his rule is often challenged by the collective drunkenness of the group. Recruitment is aggressive and deceptive; seniors actively hunt for freshmen at orientation or through word-of-mouth, promising diving experiences that rarely materialize on the first day. Once recruited, new members are immediately subjected to hazing rituals involving excessive drinking games and forced participation in late-night parties. The club's role in the series' social dynamics is central, acting as a catalyst for nearly every major plot point, from misunderstandings at the beach to chaotic road trips. Traditions include celebrating every minor event with alcohol, maintaining a shrine of empty bottles, and occasionally organizing legitimate diving trips that are inevitably interrupted by hangovers or other distractions. Despite the chaos, the club functions as a found family for its members.
