From a young age, Kurumi Mirai has aspired to become a magician. Driven by her ambition, she has spent her childhood preparing to join the prestigious Rettoran Academy of Magic.

Admitted to the standard class at the academy instead, Kurumi soon befriends Maki Kumiiru, her new roommate; and Yuzu Edel, another girl unhappy with her placement. However, to everyone's surprise, their homeroom teacher, Minami Suzuki, promises to teach the class magic anyway. Although skeptical at first, the girls start to believe that this may be their second chance at realizing their dreams and becoming wonderful magicians.

But what exactly are Rin's intentions for wanting to actively seduce Aoki-sensei, and will Aoki-sensei be able to help her to deal with them?

Demonic activity worldwide has significantly increased due to the involvement and corrupt practices of the Illuminati. To combat the unnatural influx of demons, the Vatican Headquarters decides to hold the annual Exorcist Certification Exam early and allow for as many exorcists as possible to take up the mantle. Straight from the Vatican, one of the most powerful exorcists, Lewin "Lightning" Light, arrives at True Cross Academy to help prepare the students for the exam. The ease and mastery with which Lewin performs exorcisms quickly impresses Ryuuji "Bon" Suguro, who has lost his ambition to continue his studies, and Lewin surprisingly accepts him as his apprentice. Amid the worsening situation, twin brothers Rin and Yukio Okumura are sent to locate the recently missing exorcist Shura Kirigakure, who seems to be chained to a decades-long contract with a powerful, immortal demon hiding in Aomori Prefecture's dangerous, snowy mountains.
