Usagi is the granddaughter of the leader of a prestigious ninja village, but she's such a klutz that she's never made it out of the kiddie class. Frustrated with Usagi's lack of progress, her grandfather sends her to marry Lord Hanzo and have lots of ninja babies. But the lord has no interest in her or her childbearing potential!
At the tea ceremony, Hanzo saves Usagi and takes her to his hideout in the city. Unfortunately, Mamezo is caught by the formidable Akechi Mitsuhide and forced to reveal where Hanzo's hideout is! Meanwhile, Ranmaru feels humiliated for letting Hanzo get the best of him and vows to hunt down all the ninja of Iga by himself...
