A little girl survives the massacre of her family by an evil lord who wanted to obtain a rare sword in the samurai family's possession. She is left for dead, having lost an eye and her right arm. She's raised by an aging swords-master, learns to talk like a rough samurai, and is trained to use the blade in order to pursue deadly vengeance.
