In feudal Japan, Kaede Hajime lives as a vagabond ronin, a samurai without a lord. As he spends the night at a village's inn, the innkeeper begs him to help stop a mischevious kitsune, a fox spirit, plaguing their village. But when he captures the spirit—in the form of a hauntingly beautiful man—Hajime learns that the kitsune has troubles of his own. The pearl that contains the fox's soul has been stolen, leaving him a slave to the new owner, who is forcing him to attack the village. Hajime agrees to help the fox retrieve the jewel, but living with a fox spirit isn't easy, and the budding trust between them is constantly tested. Kitsune are tricksters above all, and Hajime must decide how much of the story the fox tells him is truth. What's worse, an old comrade of Hajime's is in town, bringing with him the sour memories of Hajime's time as a samurai. Hajime must find a way to locate the thief and steal back the jewel before the thief turns the kitsune's considerable power against him.
