Minato Narumiya is a first-year student at Kazemai High School and the protagonist of the story. He was inspired to begin kyudo, or Japanese archery, during childhood after watching a competition with his mother, captivated by the beautiful sound a bowstring makes when an arrow is released, known as the tsurune. He attended an archery powerhouse middle school but developed a condition called hayake, or target panic, during his final competition there, which caused him to lose confidence and distance himself from the sport entirely.

Upon entering high school, Minato initially refuses to join the Kazemai kyudo club, despite encouragement from his childhood friends Seiya Takehaya and Ryohei Yamanouchi. His resolve changes after a chance encounter with a mysterious and highly skilled archer, Masa-san, at a shrine archery range called the Yatanomori Kyudojo. Inspired by the beauty of Masa-san's shooting, Minato decides to face his past and rejoin the club, rediscovering his passion for the tsurune.

Minato is introspective and often keeps his emotions to himself, but he possesses a deep, quiet sensitivity, especially toward the sound and feel of his own shooting. He demonstrates remarkable concentration when engaged in kyudo, sometimes to the point of becoming unaware of his surroundings. Though initially hesitant and prone to self-doubt, he grows more open and direct with his teammates as the story progresses. He values honest communication and learns to express his thoughts and feelings willingly.

His primary motivation is to rediscover and hold onto his ideal tsurune, the perfect sound of the bowstring that first moved him. This drives him to work through his target panic and commit fully to the sport. Within the story, Minato serves as the emotional and thematic center of the Kazemai High kyudo club. His personal struggle and recovery from hayake are the catalyst for the team's formation and growth, and his pursuit of the perfect shot inspires his teammates to reflect on their own reasons for shooting.

Minato's most significant relationship is with his childhood friend Seiya Takehaya, who has always been protective of him and is deeply invested in his well-being. Their bond is tested as Minato learns to rely on himself and others more equally. Masa-san, the coach, acts as a pivotal mentor, guiding Minato not just in technique but in understanding the mental and spiritual aspects of kyudo. Ryohei Yamanouchi is a warm and supportive childhood friend who helps ground him. Among newer teammates, Minato develops a straightforward rivalry with Kaito Onogi, who initially dislikes him for having quit the sport, and a more playful dynamic with Nanao Kisaragi.

Over the course of the series, Minato's development is centered on overcoming his hayake and regaining his confidence. He learns that kyudo is not just an individual pursuit but something deepened by connection with teammates. He moves from a place of fear and avoidance to one of trust and determination, ultimately realizing that his passion for archery is inseparable from the people he shares it with.

In terms of notable abilities, Minato possesses a natural sensitivity to the tsurune and an intense, focused state while shooting. He is physically well-suited to the sport, with the official profile noting his height and calm demeanor. His greatest technical challenge is managing the mental pressure that triggers his target panic, but as he grows, he learns to channel his focus constructively, becoming a steady and reliable member of the team in both practice and competition.
