Armed Detective Agency

The Armed Detective Company is a group focused on solving crimes which are considered too violent or difficult for the Military Police to handle. Often, these crimes are of a supernatural origin. Nearly all of the detectives within the company have their own special powers known as Abilities.

Shortly after meeting Osamu Dazai and his partner, Doppo Kunikida, Atsushi Nakajima is manipulated, by the former, into joining the Company against his wishes.
