Mikura, Kurokawa, and Harada are the 3 members of the Danger Service Agency (DSA). Mikura is the brawn of the group, Harada is the brains, and Kurokawa is just a bitter ex-cop who likes to think he’s in charge. They’ll take on any job as long as it involves lots of danger and, of course, money.
Not that much of it ever seems to come their way of course.
Episode 1, Shell of Love kicks off with some explosive action, with Mikura in the thick of things battling some big masked, purple dudes. The big guys are tough, able to pound holes into concrete and would most certainly take Mikura head off in order to get what they both want.
