Red-haired Nariko is a feisty one. She's got swords and she doesn't hesitate to go berserk and wreck a few blokes... just for fun.
Or maybe the storyline has something to do with revenge, an invading king with an army of millions and some ancient sword that cannot be used by mere mortals.
Either way, Heavenly Sword is good fun, and we say that BEFORE attempting to stand Nariko in a corner and swivel the camera to get a good view of her perked, polygonal ass.
