魔法陣クロノカノン•Mahoujin Chronocanon

Magic Circle Chronocanon

Karino, a girl who had been imprisoned, was finally allowed out into the world where magic was the norm. Karino possessed magic power, but she didn't know the proper incantations. So she enrolled in a magic academy with Touma, the boy who rescued her, in order to learn how to use her magic. (Source: Shogakukan, translated)
