Kodama Tadashi

Kazuhiro's homeroom teacher for Class 5, Year 2. He is in charge of physics. He is also the advisor for the girls' track team, but she is an aspirant in name only and rarely shows up for practice or even for competitions. He is a typical hard man, and his only criterion for evaluating students is their grades. He is overbearing toward students, but is low-ranking and authoritarian toward his superiors, such as the principal. He is obsessed with students' grades. It would be an unwise guess to assume that he is particularly concerned about the grades of his own class because that may be the standard by which the school evaluates its teachers, rather than the future of its students.
