Initially unfamiliar with the sport, Haruto is drawn to its challenges and the camaraderie of the school's sailing club. The club, though small and underfunded, is determined to compete in national regattas, facing off against elite teams with far greater resources and experience.

Haruto's journey is marked by his rapid development as a sailor, driven by his natural athleticism and relentless determination. He forms a close-knit team with his fellow club members, including the skilled but reserved captain, Aoi Shindo, and the strategic and analytical tactician, Riku Takeda. Each character brings unique strengths to the team, and their dynamic evolves as they navigate both the technical and emotional challenges of the sport.
