The Danger Service Agency (DSA) consists of three members: Mikura, Kurokawa, and Harada. Mikura is known for her strength, while Harada is the brains of the group. Kurokawa, a bitter ex-cop, likes to act as though he's in charge. They are always on the lookout for high-risk jobs that offer them a handsome reward. Anyone who crosses them risks their life. Their latest mission revolves around discovering the motive behind the attempted assassination of Kurokawa.
