Mizore Yoroizuka

_Instrument:_ Oboe

Mizore is a second-year student who plays oboe. She is a very quiet and introverted girl, and despite seeming hard to interact with, she has friends like Natsuki Nakagawa, Yuuko Yoshikawa, and - despite past relationship troubles - [Nozomi Kasaki](https://anilist.co/character/120724/Nozomi-Kasaki).

She likes practicing the oboe alone outside the classroom, and frequently arrives at school early, hours before the start of her classes, in order to practice. She's the only student to arrive at school even earlier than Reina Kousaka.
