Minori Nanahashi is a 17-year-old high school student in her third year. Her surname Nanahashi translates to "seven bridges," and her given name Minori blends the characters for "control/honorable," "from," and "pear." She supports her grandfather in running the family bathhouse, working there daily and forming a profound attachment to the place. This bathhouse embodies stability and continuity for her, driving her to fiercely resist any changes that could jeopardize its future. Her story progresses through her interactions with the protagonist, whom she invites to work at the bathhouse. Together, they take on tasks like cleaning and attend the Tatsuta Shrine festival, an event anchored in local cultural traditions. A defining moment occurs when Minori proposes marriage to the protagonist, aiming for them to co-manage the bathhouse—a move that reveals both her dedication to preserving the establishment and her personal vulnerability. Later, after the protagonist assures Minori's father and grandfather of the bathhouse's secure future under their joint care, she responds with pride and admiration, seeing this support as deeply validating and strengthening her trust in him. Personality-wise, Minori merges modern energy with traditional values, cherishing cultural history while embracing a contemporary outlook. Her aversion to change emerges in her reluctance to consider different futures, preferring the comfort of established routines and the bathhouse’s enduring presence.
