Story
Hazuki Kagimura is a normal girl who is usually alone. With her relationship with her new family not going so well, she retreats every day to the world of stories and books. One day, after school, one of the library's bookshelves sends her to another world with a magic school, where she meets Shizuka Tsuchimikado. She finds out that girls (called "mädchen") who attend the school are selected by old fairy tales and folk stories to wield their magic and are taught how to wield it in the school.
