Description
Ryūjirō Kotobuki is a senior student at Izu University and a core member of the Peek-a-Boo diving club, which meets at the Grand Blue diving shop. As a third-year mechanical engineering student, he serves as the club's vice president and acts as one of its co-leaders alongside his close friend Shinji Tokita.
In terms of personality, Kotobuki is very much a product of the club's famously rowdy environment. He is frequently depicted as a central participant in Peek-a-Boo's wild partying, often getting himself and other members drunk and naked. Despite this chaotic and carefree demeanor, he possesses a surprisingly charismatic side. This duality is a defining trait; he can be both the life of an alcohol-fueled party and a source of calm, dependable leadership. His charisma is particularly evident in his professional life, as he works part-time as a professional bartender, a role that requires poise and social skill.
Kotobuki's primary role in the story is that of an influential senior to the first-year protagonists, Iori Kitahara and Kohei Imamura. Along with Tokita and the other seniors, he serves as a catalyst for much of the series' humor, dragging the new members into their unorthodox traditions of heavy drinking and casual nudity. However, this behavior is balanced by a sincere dedication to scuba diving. Kotobuki and his fellow seniors take the safety and seriousness of diving very seriously, ensuring that even in their most absurd moments, the importance of teamwork and responsibility underwater is never treated as a joke.
His key relationships are central to his character. He and Shinji Tokita are presented as inseparable partners, a classic example of a Heterosexual Life-Partner dynamic, always seen together and sharing a similar boisterous personality. Together, they form the backbone of the club's leadership. He also shares a complicated history with the other senior members, Azusa Hamaoka and Nanaka Kotegawa. The group has a shared romantic past that became messy, but they eventually resolved their feelings amicably to preserve their friendship, leaving some hints of lingering emotions. Kotobuki also has a working relationship with Azusa, as they are shown to have worked together to defuse a tense situation with a troubled student on behalf of the university.
Regarding his development, Ryūjirō Kotobuki is a static character who functions more as a steadying and humorous influence on the main cast. His backstory and the established dynamics with his peers are already in place when the story begins, and he does not undergo a significant personal transformation. Instead, his role is to provide a sense of experienced stability and to showcase the strong, trusting bonds that can form within the diving club.
His notable abilities are twofold. First, he is a highly competent and experienced diver, passionate about the ocean and skilled in all related activities. Second, he possesses the unique and practical skill of being a professional bartender, a job that highlights his charismatic and sociable side, contrasting with his often-uninhibited party persona.
