Miharu was a new student at the Magical Girl Training Academy. Chosen by a magical weapon, she dreamed of awakening as a magical girl and trained hard every day. That said, the academy itself was peaceful—almost too peaceful. Even though monsters supposedly saw magical girls as "special targets for their desires," Miharu couldn’t quite wrap her head around what that meant. But one day, a powerful monster appeared at the school. A magical girl was assaulted and kidnapped, leaving behind her magical sword. The sword chose Miharu as its next wielder. Now a magical girl, Miharu teamed up with her senior, Fubuki, another magical girl, to take down the monster. However, the monster grew stronger and stronger, unleashing its primal instincts on the two of them. What would become of their fate?
