Teruyo Oshie

Acting as the dedicated homeroom teacher for Bocchi’s classmates, this instructor is affectionately known by her students as "Teru-chan." While she maintains a professional role in the classroom, she harbors a noticeable, comical fear of Nako. Her name serves as a clever linguistic play on the Japanese phrase "oshieteru yo," which translates to "I am teaching," perfectly reflecting her essential position within the school setting.
