The continent of Halkeginia is a place of turmoil, where various kingdoms, princedoms, dukedoms, and fiefdoms compete with one another to expand their territories. The nobility conspire and plot among themselves to gain influence over their lieges or even foreign ones. Situated in the heart of Halkeginia is the small yet significant kingdom of Tristein. Its most prominent feature is the Tristein Academy of Magic, where nobles from around the world come to study magic in order to become magi. Although friendships may form across national boundaries at this school, will they endure the politics and schemes of the wider world once the students depart? Louise is a student at the Tristein Magical Academy. She is known to be quite a failure when it comes to her magic. One day, a ceremony takes place in which each student is to summon a being or entity that will serve as their familiar. For Louise, her familiar appears in the form of a boy named Hiraga Saito. Somehow, he managed to be transported from his world into hers, and shortly thereafter became her familiar.
