In an unknown country closed off from the outside world for well over 500 years, the ruling dictatorship enlists the help of the Takemikazuchi family, a clan of skilled assassins who sought asylum from their nation years ago. The most highly trained member of the family is Princess Yuki, killing dissidents who attempt to thwart the ruling body. One day, Yuki discovers a dark secret that changes her life forever: her mother may have been killed by her own leader, a member of her adopted nation's ruling class.

Soon, Yuki is fighting for her life, enlisting help from the most unlikely of allies - a rebel named Takashi - while her own family attempts to hunt her down. A wild ride into a dark, apocalyptic future, where law is upheld with the power of the samurai sword, Princess Blade is a stylish and spectacular ride featuring some of the most mind-blowing fighting and special effects sequences ever seen.
