Masataka Sawatari

Serving as the dedicated homeroom teacher for the class, this instructor possesses a singular, humorous preoccupation with dating female university students. He frequently finds himself caught in counseling sessions with Yamai, leading to a recurring comedic trope where his glasses shatter whenever her eccentric chunibyo antics are mentioned. Despite the chaotic nature of his students' outbursts, he remains a central, albeit frequently stressed, figure within the school's daily social dynamics.
