You find yourself in a world where all-girl highschool (no males) as females become exorcists which is part of an organization club that’s been running for centuries to stop evil demonic beings (Goblins, Orcs, organic Walls, and Human Males even) that exist in this world from taking the world completely using imbued weapons or having skills honed from the very club that stops the threat but at what cost?

The club’s main room is a rather unassuming sight to behold in an ordinary Japanese high school. Though you may expect a plethora of ancient tomes, relic weapons, and strange talismans to be laying about in an exorcism club, that’s far from the case. In fact, the only thing of note is the simple black school uniforms worn by the members, along with the colored bandanas that signify each member's rank based on year or skill alone.
