Tomonari Mashima

Tomonari Mashima is a supporting character in the Classroom of the Elite anime. He serves as the English teacher and homeroom teacher for Class 1-A (the top-ranked class) at Advanced Nurturing High School.

In the anime portrayal, he's depicted as a serious, principled, and dedicated educator who takes his responsibilities very seriously and adheres strongly to morals and fairness without compromise. He's well-respected by his own Class A students and stands out among the faculty for being relatively selfless and integrity-driven compared to some other teachers who may prioritize personal gain.

He appears in various school events and exams (including more prominent roles in later seasons, such as interactions involving special exams and school politics), often acting in a composed, authoritative manner.
