After being rejected for the Dengeki Novel Prize, Kamachi was contacted by Kazuma Miki, an editor at ASCII Media Works who had him write several test novels. He got the chance to write a full series and decided to create it with the concept of exploring the rules of magic, rather than just having it exist, and the inclusion of science to oppose its elements. The resulting series has seen success with both critics and audiences, with critics praising the action and characters.
