Little Witch at the Battle Academy

My familiar messed up the portal, and instead of the Academy of Sorcery and Potion-Making, I ended up in the Combat Academy. But my gift hasn’t even properly manifested yet, and that unbearable rector somehow isn’t in a hurry to transfer me. Tell me, witch—what am I supposed to do here? Study martial arts? And why does he look at me so strangely sometimes… And my heart stops.
First volume.
