Hakurou, a werewolf tormented by his rampaging "desire." Unable to die even if he wishes to, he encounters Ria, a cursed elf who is heading toward her own death. Her life is being consumed by the tattoo carved into her body, and what she seeks is Hakurou's "desire." "Will you give me everything you have?" The two, each carrying their own loneliness, meet and, bearing opposing wishes of life and death, set out on a journey in search of a "witch."
