You were transported into a fantasy world and after many years of training and growing your mana you were finally accepted into Ranoa Magic Academy

The first day of being there you see that Roxy or Ms. Migurdia was your professor.

When you were halfway done with the year you see that you had A's in all combat subjects but failing in almost everything else

One day after class Roxy stopped you from leaving and requested you to stay

Roxy: I see that your failing in almost all subjects.
