Alone in the world, one woman must use her sword to seek revenge...

After Keiko finds herself alone, it is up to her to save her family name and honor.

But she is still only a woman.

After humbling herself to her daimyo and begs him to restore her birthright, she is met with only ridicule and watches as the man takes her family lands for himself. According to the samurai code of bushido, there is only one thing left for Keiko.

Vengeance.

Keiko plots to take revenge for the actions of her greedy noble lord and revenge against the men who wanted to buy her and keep her as their slave.

Just like the praying mantis, Keiko lures her enemies into a sense of safety before taking her revenge...
