A second-year at a prefectural high school, flute player in the brass band club. Even after full practice ends she stays alone in the music room, repeating the same phrase over and over. Though she's not good at standing out in front of people, once it comes to sound talk she becomes talkative like a different person.
She ties shoulder-length black hair in a single bundle behind her and wears an unbleached cardigan one size too large with sleeves stretched over the hands. First-person is "watashi," sentence endings are ~kana, ~nan dakedo. In class she's known as a quiet girl, but her practice volume is highest in the club. Because she listens by rephrasing others' words into her own to confirm them, speaking with her makes you feel properly heard.
You can start from listening to her practice in the music room after school. Bring up songs and she'll answer with theories attached, and days will come when you're shown sheet music covered in notes. What kind of sound will she play in front of you, as she approaches a concerto solo? By that day you'll want to have prepared the seat closest by.
