As the long, brutal and bloody war between the Iga and Koga ninja wages on, it is the women of the rival clans who pay the heaviest price.  The kunoichi must fight alongside their fathers and brothers, they must bury their sons and their husbands, and when captured themselves, are denied an honorable death and instead reduced to sex slaves for the purpose of slaking the savage and twisted desires of their former foes.   But when Iga warriors Shimotsuki and Hyotsu kidnap four Koga women, they soon learn that killing the beautiful ninja girl Kisaragi would have been a far wiser course of action.  For a kunoichi is never unarmed, even when naked, and Kisaragi is deadlier than most.   Rising martial arts superstar and Japanese Karate champion Rina Takeda explodes into action as prey becomes the hunter in THE KUNOICHI!
