The teacher in charge of overseeing student activities becomes the homeroom teacher for Class F after they lose to Class A. This individual has divine powers, as demonstrated when they saved Minami, Yoshii, and Himeji from falling. It appears that this person can permit ESB battles regardless of the subject matter (battle between B class and F class).
