Jun Inoue

Serving as both the math instructor and the homeroom teacher for Yuuki Hase’s class, this educator is frequently seen reprimanding Hase for his consistent struggles with mathematics. Beyond his academic duties, he played a pivotal role in the story by providing Kaori Fujimiya with her own key to the school rooftop. His presence serves as a constant, disciplinary force within the classroom while simultaneously facilitating key moments of connection between the main characters.
