The Danger Service Agency (DSA) is comprised of three individuals: Mikura, who serves as the group's physical strength; Harada, who utilizes his intellectual abilities; and Kurokawa, a former police officer with a bitter disposition who believes he holds authority. This trio takes on any job that involves danger and payment. It is crucial not to cross them if you wish to survive long enough to enjoy dinner. Their most significant case may revolve around determining the motive behind someone's desire to assassinate Kurokawa.
