A mercenary with no memory and a sheltered woman on opposite sides of the world are the same person fractured across two realities, and the show spends all 26 episodes pulling you toward the moment you understand what that means. The mystery isn't about solving a plot, it's about watching two halves of a broken consciousness claw toward each other through gunfire and theology and fever dreams that don't obey continuity. By the finale, you realize the real horror was always that knowing the truth might not save either of them.

Margaret Burton, daughter of an aristocratic family, lives a quiet, sheltered life in the peaceful European nation of Nafrece. She has little freedom, her maid Elenor is her only companion, and an aircraft accident twelve years ago left her with no memory of her life before it. Far away, in the civil war torn country of Gazth-Sonika, a mercenary called Madlax fights with almost supernatural skill. No one knows her real name, her age or her past. The two women's lives seem entirely separate, yet they are linked by mystery and by a holy book that the shadowy organization Anfan is also seeking. As each follows her own path, they draw nearer to a truth they may not be able to bear. The series mixes action, drama and psychological mystery with supernatural elements, and it centers on war and the toll that violence takes on people.
