Gun Woman (2014)

Gun Woman (2014) is an assassination film that toes the line between action and horror. A grief-stricken doctor (Kairi Narita) buys a young woman with the intent of using her to get his revenge. He trains her to be the perfect assassin, putting her through intense preparations. The catch: The assassin (played by Asami) has to enter a brothel that caters to very, eh hem, unusual tastes to reach her target (played by Noriaki Kamata)—and will be strip searched in the process.  To bypass this roadblock, the doctor sews individual gun parts inside her body, which she must cut out once she gets inside. She then has a measely 22 minutes to put the gun back together and kill everyone inside the brothel before she bleeds to death. 

Director Kurando Mitustake intersperses this gruesome thriller with plenty of delicious half-naked men, though. Kairi Narita spends some of his training time sans-shirt, while Noriaki Kamata shows off a little backsack at the brothel, too. Whatever the genre, this movie is sure to intrigue in every way possible.
