Usagi goes from village darling to castle clown, but that's not going to stop her from doing her best! She's going to get her man and become a ninja, and not even two super-skilled shinobi beauties can stop her!

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!

Usagi will remain in Ieyasu's household forever, apart from her beloved Hanzo, unless she can come up with an elixir of eternal youth. Usagi journeys to a mountain to find a hermit who supposedly knows how to create such an elixir, but he has no intention of sharing his knowledge with her. Even if Usagi is successful, there are others who don't want to see her free to return to Hanzo's arms...
