The Department of Inquisition (教理聖省異端審問局), also referred to as the Inquisitorial Department, the Bureau of Inquisition, or simply the Inquisition, is a special division of the Ministry of Vatican Papal Doctrine—the department responsible for promulgating and defending the creed and doctrine of the Catholic Church. Its membership consists of elite warrior monks, known as Inquisitors, who serve the Ministry of Doctrine as the chief enforcers of the Catholic faith. Their reputation as a group of uncompromising hardliners—dedicated to the Vatican and committed to their duty without question—has earned them the nickname "Fangs of the Church."
