An exceptionally charismatic and attractive young woman, who is at the same time the best mercenary agent in Gazth-Sonika with 98% mission success rate. Like Margaret, she doesn't remember anything before twelve years ago (though she hasn't lost her language knowledge), except for the word "Madlax", which she has adopted as her code name, and a brief flashback of a gun in her hands and her father walking away - Madlax believes that her father is still alive and fighting somewhere in Gazth-Sonika. While she is the best fighter in the country, easily able to dodge bullets with her Gun Kata fighting style and take down a small army all by herself, Madlax hates war and acts very gentle and lady-like in private life. She fights only to bring a rapid end to all fighting and, when Vanessa Rene shows her that Enfant is behind the war, Madlax immediately seeks to destroy it, no matter the personal cost.

Her Pistols of choice are the Sig Sauer P210.
