Seventeen years ago, the “Conjurer of Calamity” tore open the boundary separating the human world from the demon realms. In the years since, the earth has become crowded with otherworldly beings and fiends—zombies, vampires, half-lizard men, and more. Yet after seventeen years, these creatures now live alongside humanity in peace. At Banmaden, a school where mixed-species students study together, three pupils spend their days uncovering the strangeness of their surroundings. Fox demon Hisagi Hatsune, raccoon demon Futatsuiwa Mami, and demon dog Kousenji Hoyu roam both campus and town, chasing down obscure urban legends and solving the mysteries hidden within them.
