She is a second-year student (a third-year student in Liz and the Blue Bird and Sound! Euphonium: The Movie - Our Promise: A Brand New Day) who plays the oboe in Kitauji High School Concert Band.
Mizore is a fair-skinned girl with straight medium-length blue hair that has strands framing her face, with bangs cut evenly. She has cherry-red eyes.
She is usually seen with a standard Kitauji High School uniform for girls.
Mizore is a very silent girl, and despite seeming to be distant towards others, she has a close friendship with Natsuki Nakagawa, Yuuko Yoshikawa and Nozomi Kasaki. She likes practicing the oboe alone outside the classroom, and frequently arrives early to school, hours before the start of her classes, to practice. Mizore is the only student to arrive at school even earlier than Reina Kousaka.
As a minor character in season one of the anime, Mizore had a very small role with no speaking lines. She was present as a cameo in several episodes, occasionally seen quietly playing her oboe.
In the theater version, there is an additional scene where Mizore speaks with Yuuko, which takes place before Yuuko asks Reina to purposely lose in the audition.
In season two, Mizore is revealed to have had a fallen friendship with former band member Nozomi Kasaki after the schism of the previous year. Nozomi now wishes to rejoin the band because of the new attitude of the ensemble under Noboru Taki's direction. Because of Mizore's extremely high value to the ensemble, due to her soloistic playing being a huge contributor to the band's overall success, Asuka Tanaka refuses to allow Nozomi to rejoin the band out of concern that Mizore will be emotionally compromised. However, due to an unexpected move by Nozomi to talk to Mizore causing her to run off, the latter managed to talk things out with Nozomi and restore their friendship. It is also revealed that Mizore played the oboe for the sole reason that it was the only thing that connected her with Nozomi.
In Liz and the Blue Bird, Mizore and Nozomi's friendship develops further. Mizore becomes less dependent on Nozomi and decides to go to a music school after graduating, while Nozomi decides to go to a regular university.
