Mikura is a beautiful young assassin who works for a mysterious company that specializes in murder and blackmail. However when Mikura is assigned to kidnap a seemingly hapless baseball team owner named Momokichi, both she and the company soon find that they have made what could be a fatal error. Momokichi turns out to be powerful underworld boss who is not at all easy to abduct, and who is quick to anger. Eager for the challenge, Mikura becomes determined to complete the mission, only to find that Momokichi has a daughter who every bit as vicious and talented as she is, and who is also as eager to dispatch Mikura.
