Hanako is a lonely white fox that's an outcast in the town of Machi that she's lived in for ten years since her brother disappeared. While out hunting one day, a strange red fox suddenly confronts her and knows the meaning of her name in the ancient language that the Great Fox spoke. Hanako is fearful of this newcomer, but befriends him as they decide to confront the menacing Count Ecim after she tries to steal a mouse Hanako captures. During their journey, they encounter two rabbits named Raja and Belle that are fleeing from the oppressive Dr. Tarroc who makes them wear pendants around their necks that contain their souls. Hanako is skeptical of such a claim, but when the foxes and the rabbits are forced to rely on each other to survive, they band together to find out what lies in the ominous Castle Beyond the Clover. What secrets lie hidden inside the castle and the past of Hanako and the others?
