Magical Geubsig:Amsalbeobsa

Garin, an ordinary high-school girl, is given magical powers that can help fight all kinds of “villains” around her. The catch? The magic transformation is nothing short of mortifying to the teenager. But do not judge a book by its cover! With the power vested in her thanks to a peculiar god’s random blessing, Garin and her gang free humanity from the evil plot to villainize the world–and hopefully boost her grades along the way.
