In grand Onechanbara tradition, the female leads of Onechanbara Z do their vampire slaying in impossibly skimpy outfits. But if main character Kagura's standard attire just isn't revealing enough for you, you'll want to be sure and pick up the game's first print run, which includes this:

Onechanbara Z is due for Xbox 360 release on January 19.
