Yashahime: Princess Half-Demon #4

Can the three teenage daughters of demon dog half-brothers Inuyasha and Sesshomaru save their parents, themselves, and both realms from the menace of the seven mystical Rainbow Pearls?

While the trio continues marching westward, they run into a slimy beast that kidnaps princesses! Coming to their aid is Tokichiro Kinoshita, a cunning peasant who will one day become a historical legend, and he devises a clever—and embarassing—plan to lure the monster out of hiding. Then, the girls battle the demon and witness the sorts of tricks that Inuyasha himself would pull off!
