Madlax (マドラックス Madorakkusu?) is a 26-episode anime television series that was produced in 2004 by the Bee Train animation studio. According to the composer of the series, Yuki Kajiura, the director Kōichi Mashimo created a list of brief descriptions of every recurring character for her to base their respective musical themes upon. She refers to this list as "Mashimo Menu" and commented that the director's descriptions provide deeper insight into the characters.
Margaret Burton (マーガレット・バートン Māgaretto Bāton?), born on 14 July 1992, is a clumsy, absent-minded 19-year-old girl who attends an elite college for aristocratic families' children in Nafrece. Her memories of her own life are limited to its last twelve years, the word "Madlax", and vague recollections of something important connected to an unusual "picture book" she possesses.
Margaret is ultimately the central character of the story, as she is the person who has the Gift, a mysterious ability to alter the reality. Twelve years ago, she and the person who later became known as Carrossea Doon, survived a plane crash in Gazth-Sonika and interrupted the stand-off between Friday Monday, who unintentionally caused the accident while accessing the Sanctuary (see Terminology), and Colonel Richard Burton, Margaret's father. Although Burton was victorious, Monday, with his last strength, chanted the Words of Awakening and put him into trance, forcing to shoot his own daughter. Protecting herself, Margaret shot her father and, to flee from the guilt, used her Gift to split herself into three personae: one who retained the Gift, one who took the sin of patricide upon herself, and one who kept the memories of this. Since that moment, the person known as Margaret Burton became but a third of her former self, still possessing the Gift, but having lost all memories.
