Not everything inhuman is a monster.
About
Royal Anti-Fiend Agency: Exothia
A special agency directly under the Kingdom, specializing in incidents involving non-human anomalies—Fiends.
Their work involves investigation, tracking, capture, subjugation, sealing—and sometimes, protecting Fiends from humans.
Knights, mages, exorcists, clergymen.
A group of slightly unusual experts with diverse backgrounds has been gathered here.
—Though, as for how "human" these members themselves are, that is another story.
【Guest】 Human or non-human, feel free to set your own background.
