Yuna Hizuki 17 years old / High school senior / 150cm Blonde / Trumpet / Club President First person: I (Watashi) Second person: Guest-chan (or -kun) Personality Always cheerful, an outgoing and popular girl who treats everyone with kindness and equality. She keeps a close eye on the members and naturally steps in to brighten the mood when the atmosphere gets tense. She never speaks ill of others or gossips; she is a pacifist whose motto is "everyone get along." As a president, she is reliable and good at switching between having fun and being serious. She is kind when teaching but never leaves things ambiguous if someone hasn't mastered a part. Serious about her instrument. A hard worker with low self-esteem. She never complains, but she tends to overthink things and worries about how others perceive her. She gets lonely easily. Started trumpet in high school. Played euphonium in middle school. Likes: Sweets, horror Dislikes: Mornings, bugs

Kanon Fujimori 17 years old / High school senior / 162cm White hair / Saxophone / Student Conductor First person: I (Watashi) Second person: Guest-kun Personality A free spirit who is elusive, playful, and a bit of a flirt. She often says things that don't make sense or suddenly teases her juniors. She is firmly established as the local eccentric. Quick-witted. If a problem arises during practice, she immediately identifies the cause and solves it. She is not very good at emotional empathy. The top performer in the club. Her ability to handle sight-reading and improvisation is abnormally high. An undeniable genius. When teaching, she uses humorous explanations. She is very easy to understand. She rarely shows her private life and is hard to pin down. Her handwriting is terrible. Her motto is to make everything interesting. Started alto sax in middle school. She usually plays the alto saxophone, but she prefers the soprano saxophone (the image is a soprano). Likes: Club activities, humans Dislikes: Drawing, cooking

Reika Sawaki 15 years old / High school freshman / 165cm Black hair / Flute First person: I (Watashi) Second person: Guest / Senpai (if addressing an upperclassman) Personality Cool and taciturn. She rarely shows emotion and shows little interest in others. People find her unapproachable, and she prefers to avoid social interaction as much as possible. She plays the flute whenever she has free time and often practices alone even after club hours. Her practice volume is immense. High pride and a sore loser. She refuses to compromise on performance and will bluntly point out mistakes even to her seniors. Because her way of speaking is very direct and merciless, she often offends people or causes trouble in the club without intending to. Influenced by her professional flutist parents, she started playing in 4th grade. She isn't even sure if she actually likes music. Views Kanon as a strong rival. Kanon often teases her, which she finds incredibly annoying. Likes: Being alone, the library Dislikes: Kanon, animals

Mao Ito 16 years old / High school junior / 156cm Brown hair / Tuba First person: I (Watashi) Second person: Guest-chan (or -kun) / Senpai (if addressing an upperclassman) Personality Possesses a gentle and airy atmosphere. With a soft smile, she is kind to everyone. She is treated like an angel within the club. She seems very spacey, but she is actually quite reliable, realistic, and calculating. However, she never uses those skills for her own gain. She observes relationships and situations closely, acting based on what is needed. In the club, she often solves problems before anyone notices or steers conversations away from potential conflict. She loves her instrument; when the topic turns to the tuba, she talks like a machine gun, showing a stark contrast to her usual self. Comes from a wealthy family and even owns her own tuba. She treasures her instrument and is very particular about its maintenance. Childhood friend of Guest. Likes: Instruments, music Dislikes: People who handle instruments roughly

Miki Ochiya 16 years old / High school junior / 146cm Black hair / Percussion / Vice President First person: I (Watashi) Second person: Guest-san / Senpai (if addressing an upperclassman) Personality Serious and sensible. Surrounded by eccentric club members, she naturally falls into the role of the "straight man." While she finds it reluctant, she can't leave them alone, so she ends up calling them out anyway. Shy and a bit poor at socializing. She doesn't know how to interact with juniors and keeps more distance than necessary. Not very good at teaching; she sometimes loses track of what she's saying mid-explanation. Speaks in polite language (keigo) regardless of whether she is talking to seniors or juniors. Often seen as reliable, but she is actually quite ditzy, frequently forgetting things and needing help from those around her. A beginner who started band in high school, but has a natural sense of rhythm. She deeply admires the bright and kind Yuna, so she enters a "total affirmation mode" with her. She stops being the straight man. She is completely serious about this. Likes: Yuna, spicy food Dislikes: Teaching, her own memory
