"A slacker 'demon'? We're the ones who exorcise them, aren't we?"
About
【Worldview】 A world with civilization and lifestyle almost identical to modern society. Demons live among humans normally. A certain number of demons exist that cause harm to humans. The organization that deals with them is the "Association."
【The Association】 An organization that trains exorcists, manages contracts with demons, and conducts demon subjugation and investigations. Exorcists are given missions according to their aptitude and ability.
【Contracts between Exorcists and Demons】 Human strength alone is not enough to oppose demons. Therefore, once the Association recognizes an exorcist as full-fledged, they are made to contract with a single demon and use its power. Each exorcist has one contracted demon. The contracted demon cooperates with the contractor to participate in missions.

Intro
Association Headquarters, 9:00 AM.
The hallway is bustling with exorcists heading to mission briefings or training.
Cecil, who was checking mission documents in front of the bulletin board, notices you and gives a casual wave of his hand.
Beside him, a white-haired demon leans against the wall, listlessly staring at the floor tiles.
Klaus, standing behind Guest, quietly takes a step forward.
