- “I don’t believe I’ll lose to others just because they spend a little more time than me.”
- “I don’t want to end with just ‘I’m glad I came to Kansai.’ If I’ve come this far, I want to take Kitauji’s sound to the whole country.”
- “Yay! My euphonium got praised!!”
- “Then, I won’t say it. See you!”
Early Life and Middle School
Asuka was born to Masakazu Shindo and Akemi Tanaka, but her father left when she was two. She grew up with her mother. In first grade, she received a euphonium and notebook in the mail from her father. Her mother did not like her playing music and they fought, so Asuka made a deal: she would earn top grades if she could keep playing.
First Year of High School
Asuka chose to attend Kitauji High School because it was close to home. She was selected as the new-student representative and joined the band’s bass section. Asuka stayed in the club even when other first-years quit, focusing on her music. She refused the offer to become band president, taking the job of vice president instead.
Second Year of High School
Asuka became the unofficial leader of the bass section, mentoring new members like Natsuki Nakagawa. She remained neutral during the band’s trouble, only stepping in when it suited her. She helped host the school concert and influenced music choices.
Third Year and Band Transformation
When Noboru Taki became the new band adviser, the band decided to aim for Nationals. Asuka, now assistant leader and drum major, played a key role in helping the band adapt and improve. She was usually unconcerned with others’ personal problems, but started thinking about her approaching graduation and leaving the euphonium behind.
Kansai Competition and Personal Challenge
Kitauji qualified for the Kansai Regional Competition. Asuka wanted to win and dreamed of performing at Nationals, where her father would be a judge. When her mother demanded she quit band for university entrance exams, Asuka was forced to temporarily leave the group, hurting team morale.
Asuka confessed her story, fears, and dream of performing for her father to Kumiko Oumae in a heartfelt moment. Inspired by Kumiko’s encouragement and a strong exam score, Asuka bravely convinced her mother to let her return, just in time for the Nationals team selection.
National Competition and Graduation
Kitauji played at Nationals but only won a bronze medal. Asuka was overjoyed when she received praise from both her peers and, through Taki-sensei, her father—finally hearing, “Beautiful sound.” She thanked Kumiko and gave her the treasured notebook.
After the competition, Asuka shifted her focus to university life but sometimes visited the band. She attended graduation and, instead of saying goodbye to Kumiko, said “See you!” while handing her the notebook containing “Sound! Euphonium.”
After Graduation
Asuka shared an apartment with Kaori Nakaseko and kept close ties with old bandmates. She helped with reunions and band advice, passing on knowledge and encouragement to the next generation.
- Asuka always carries simple school supplies and dislikes wasting time or effort.
- She loves choco-chip butter cookies and often snacks on them.
- Her self-confidence and independence inspire many, but she keeps her most sensitive feelings deeply hidden.
- She often says her only “true love” is her euphonium.

- Her bicycle is a green RENAULT 266L Classic-E with a basket, matching her practical style.
