Description
Iori Kitahara, a first-year mechanical engineering student at Izu University, begins as an ordinary student yearning for tranquility but finds his life upended after moving into his uncle Toshio Kotegawa’s dive shop, Grand Blue. Despite lacking swimming skills, he is coerced into joining the Peek-a-Boo diving club, disrupting his hopes for a typical college experience. A graduate of an all-boys school, he sought coeducational camaraderie but instead navigates the club’s raucous rituals of heavy drinking and partial nudity.
Possessing a muscular build and straight dark blue hair (ranging from black to light blue in anime), his light skin defies frequent ocean exposure. While casual hoodies or jackets dominate his wardrobe, he often appears scantily clad during the club’s rowdy gatherings.
Initially resistant to the club’s chaos, he gradually embraces diving with genuine enthusiasm. His personality shifts from reserved newcomer to boisterous yet deeply loyal friend, defending peers like Kouhei Imamura from mockery and supporting Aina Yoshiwara against bullies. Observant and empathetic, he uncovers hidden struggles, from Sakurako Busujima’s heartbreak to the Kotegawa family’s fractured communication.
Family tensions simmer beneath his carefree exterior. His younger sister Shiori resents bearing responsibility for their family inn due to his perceived unreliability, though he urges her to chase her own dreams. With cousins Nanaka and Chisa Kotegawa, dynamics fluctuate: Nanaka monitors him protectively, while Chisa’s initial disdain evolves into a bond blending sibling rapport and ambiguous romantic tension. Chisa’s jealousy over his female interactions fuels a pretense of dating him to deter others.
His academic journey is riddled with comedic missteps, including failed cheating attempts and an original song leaked by Shiori, becoming a recurring humiliation. He displays hidden talents in tennis, volleyball, and guitar, though his musical efforts draw mockery. Frequent participation in drinking rituals hones his remarkable alcohol tolerance.
A pivotal Okinawa trip sees him prioritize mending Chisa’s family rifts over personal plans, cementing their trust. His growth balances the club’s hedonism with an unyielding core of sincerity, charting a path from naïve freshman to a loyal figure valuing camaraderie and integrity.
