Mirei plays the tuba and is very skilled, even more than her upperclassmen when she enters the club.
She comes from a strong music middle school where she was in the top band for all three years.
She can easily play high notes and read difficult music at first sight.
She focuses on having a clear "ideal sound" and makes sure she can play in any style: soft, loud, sharp, or gentle.
Mirei keeps a notebook (with ultramarine pages) where she pastes cutouts of the full band score to study every part.
Her main tuba is a Yamaha YBB-632, different from her friends' tubas.
(Hazuki Katou: "Is there anything I should watch out for during practice?")
— "I think it's important to imagine the ideal sound. Also, I try to practice making lots of different sounds: soft, loud, sharp, gentle... I want to make sure I can produce any sound the piece calls for."
(Yuuko Yoshikawa: "Are you always thinking about stuff like that, Mirei? You're so smart!")
— "It's not about being smart. If you only do your favorite exercises, you can't adapt when playing real songs. That's why I always practice the basics, thinking about how they fit into the music."
— "You have to understand why you do basic practice, or it loses its value. People say effort doesn't betray you, but practice without thinking can easily betray you. Flashy parts are fun, but I want everyone to focus on the basics."
— "The instrument I hold in my arms is the color of dreams."
Early Days and Middle School
Mirei started music in first year of middle school hoping to play the trumpet, but her height got her assigned to tuba.
She wasn't excited about tuba at first, but being in the top group for three years made her proud.
She saw North Uji High School’s big music success and decided to join them for her own high school.
Joining the Band
When Mirei joins North Uji’s band, she outshines some older students, including Hazuki Katou.
Her skill makes her stand out, but her cold attitude creates friction with others.
She especially keeps her distance from her classmate, Satsuki Suzuki, even though Satsuki tries hard to be friends.
Struggles with Fitting In
During practice for the Sunrise Festival, Hazuki points out something about Mirei’s instrument.
Mirei gets upset that someone less skilled is telling her what to do and ends up storming out.
Alone, she confides in Kumiko Oumae and Kanade Hisaishi about how she feels left out and troubled by her own pride.
Turning Point
With help from Kumiko and Kanade, Mirei realizes she misunderstood her friends.
She decides to try opening up more, starting with accepting her nickname “Micchan.”
After this, she gets closer to her friends and becomes more comfortable in the group.
Progress and Leadership
Mirei continues to grow, both musically and socially.
She helps train new members and later becomes the drum major, leading rehearsals and playing a big part in band performances.
She is chosen for this role because everyone trusts her skills and clear thinking, helping support the new leaders Ririka Kenzaki and Kanade.
As a Role Model
Her efficiency, high standards, and honesty set a strong example for her younger bandmates.
She’s strict but fair, and the band comes to rely on her.
She leads the band in big events like the parade in Mahiru Island, where her dedication is admired by all.
Satsuki Suzuki
Mirei and Satsuki are classmates and both play tuba.
They went to the same elementary school and were called “W Suzuki” because of their surname.
Satsuki tries hard to be close with Mirei, but Mirei pushes her away at first because of her own struggles and jealousy.
After their big argument and making up, Mirei becomes friendlier, though she's still embarrassed to say she "likes" Satsuki.
Their dynamic is often seen as a “tsundere” (cold outside, warm inside) friendship.
Hazuki Katou
Hazuki is a second-year tuba player and Mirei’s senior.
At first, Mirei looks down on Hazuki because Hazuki started music later and is not as skilled.
Over time, Mirei warms up, and they share a “good cop, bad cop” style while training younger members.
Mirei can sometimes be blunt with Hazuki, but it comes from caring.
Kanade Hisaishi
Kanade is a fellow first-year in the low brass section (euphonium).
Kumiko asks Kanade to help Mirei fit in.
Mirei becomes comfortable with Kanade, sharing personal feelings and sometimes deep talks about music.
Motomu Tsukinaga
Motomu plays double bass in the same section, but they aren't very close.
They end up in the same class, but don't interact much.
Suzume Kamaya
Suzume is a new tuba player, younger than Mirei.
Mirei acts as a mentor, sometimes surprised by how quickly Suzume learns.
Ririka Kenzaki
Ririka plays oboe and becomes the new band leader.
Mirei trusts Ririka's leadership and supports her as drum major, acting as the technical pillar of the team.

Mirei likes ultramarine blue and uses a notebook with blue pages for her music studies.
She enjoys karaoke and reading boys’ manga.
She is good at making puns.
Her family has a big Japanese-style room where she helps host band gatherings.
