Mireille Bouquet is a professional assassin, and a very good one at that. But when she follows up an E-mail from a young Japanese girl named Kirika Yumura, inviting her to take "a pilgrimage to the past", her life becomes even more dangerous than it already is. Now, with a haunting melody invoking the memory of an event long past, Mireille and Kirika decide to work together to find the truth about a thousand-year-old organization that has controlled both of their lives since before they were born.
