In modern day Japan, Kagetora is a young ninja with a "duty". His current master offers a new duty, something he is not familiar with at all. Instead, of the usual bodyguard duty, he is the martial arts instructor of his master's daughter, Yuki. Being both her protector and instructor, Kagetora trains the "Hime" Yuki.
