Description
Kaho Hariya is a supporting character who appears in the third season of the anime, introduced as a new first-year student at Kitauji High School. She joins the concert band and plays the euphonium, an instrument that places her in the same section as the club's president, Kumiko Oumae.

In terms of background, Kaho enters Kitauji High School alongside her three close friends from childhood: Sari Yoshii, Suzume Kamaya, and Yayoi Kamiishi. The four of them decide to join the concert band together. Prior to high school, Kaho was a member of her middle school's manga club, where she developed a love for drawing, and she has no significant prior experience with brass instruments.

Kaho has a personality that is best described as quiet, timid, and gentle. She often displays a dreamy and somewhat absent-minded demeanor, which her seniors sometimes describe as unconventional. She is not one to dominate a conversation, preferring instead to listen to others with a warm and genuine smile. Kaho is also known for her contagious laughter, easily finding joy in simple jokes and wordplay, which helps create a pleasant atmosphere among her peers. She is a very approachable and sweet-natured girl, though she can be easily flustered or nervous, especially when interacting with upperclassmen she admires or finds intimidating.

Her primary motivation is to do her best and improve as a musician, despite starting as a complete beginner. She wants to contribute to the band and find her place within a new and demanding environment, leaning on the support of her childhood friends and her more experienced seniors for encouragement and guidance.

Kaho's role in the story is as a newcomer whose journey represents the challenges faced by first-year students in a highly competitive band. Her struggles and growth help to highlight the supportive atmosphere fostered by the club's leadership. She is part of a wave of new talent that the third-year president, Kumiko, must help guide. Much of Kaho's early story focuses on her intense training for the Sunrise Festival parade, where she struggles with marching and playing simultaneously. Her perseverance during this time allows her to overcome these initial hurdles and improve her skills.

Key relationships define much of Kaho's experience. Her strongest bonds are with her three childhood friends: Sari Yoshii, a clarinetist who is her oldest friend and confidant; Suzume Kamaya, a tuba player known for her playful and humorous nature; and Yayoi Kamiishi, also a tuba player who is athletic and caring. Among the upperclassmen, Kaho looks up to Kumiko Oumae as a distant and respected figure, often feeling nervous in her presence. She shares a particularly close and relaxed relationship with Mayu Kuroe, a fellow euphonium player who offers her kind words and musical support. She is also wary of her second-year senior Kanade Hisaishi, who is calculating and enjoys playfully teasing her, leading to many awkward but comedic interactions. She admires Mirei Suzuki, a skilled second-year tuba player, for her musical ability and elegant demeanor.

Throughout the season, Kaho undergoes notable development as a musician and as a person. Initially struggling with the most basic techniques like fingering and intonation, she dedicates herself to practice. With patient instruction from upperclassmen like Mirei Suzuki and the faculty advisor Michie Matsumoto, she improves dramatically over the summer, eventually reaching a level comparable to other experienced beginners. Her ability to persevere through tears and frustration, pushing past her initial failures, is a testament to her quiet determination. While she remains a shy and gentle girl, she gains confidence in her own abilities and finds great satisfaction in her small daily victories.

Kaho's notable abilities extend beyond her musical instrument. She is a talented artist with a special skill for drawing flipbooks and manga, a hobby she cultivated in her middle school's manga club. Outside of music and art, her most notable talent is perhaps her ability to lighten the mood; her genuine, easygoing laugh is described as her secret weapon for cheering up her friends.
