Long before the western world began to view samurai warriors as inherently male, there existed a group of female samurai, every bit as powerful and deadly as their male counterparts. They were known as the Onna-bugeisha. They were trained in the same way men were, in self-defense and offensive maneuvers which ensured protection in communities that lacked male fighters. In this game you take on the role of three famous Onna-bugeisha to defend your village against waves of attacking enemies. Progress to unlock new characters and special abilities that would allow your to survive the harder difficulties.
