Shinta's passion lies in observing schoolgirls, specifically their uniforms and breasts. Contrarily, Shirasu is frantically seeking to expand the Fishing Club's membership. As a newcomer, Shinta catches Shirasu's attention and is persistently urged to join the club, despite his lack of interest in the activity. Despite his refusals, events transpire that lead to Shinta being rescued from bullies by Nagisa, known as "Tsuri-Chichi" for her exceptional fishing abilities. Nagisa's expert skills and generous nature, coupled with her impressive bosom, alter Shinta's perspective on fishing and motivate him to pursue it seriously, as she assures him of his potential as a professional fisherman.
