Mikura, Kurokawa, and Harada form the Danger Service Agency (DSA). Mikura serves as the muscle of the team, Harada provides the brains, and Kurokawa, an ex‑police officer with a bitter streak, fancies himself the leader. The trio accepts any assignment that offers plenty of danger and a good payday. If you hope to survive long enough for dinner, you would do well not to cross them. Their most significant case involves uncovering the motive behind a plot to have Kurokawa killed.
