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 and Hanzo finally return to Iga, where a wedding banquet awaits them. Usagi couldn't be more thrilled that her dreams are coming true! Unfortunately, the arrival of Oda Nobunaga's troops puts an end to the festivities. Can the Iga ninja protect their home against such a large army?
