Mikura, a member of a mercenary team, is asked to kidnap a baseball owner, Momokichi Momoi. The problem is that Momokichi is well connected with the mob and his daughter, Momomi, is a skilled shooter. Mikura and her team have to find a way to get the mission done and they might have a way.

Mikura and the Danger Service Agency are hired by a mysterious old man to kidnap Momokichi. But during that attempt, they run afoul of Momomi. Before the resulting firefight, Momokichi dies when his head falls on a ventilation pipe. Now Mikura and the DSA have to come up with a new plan before they end up as Momomi's next victims.
