Madlax

Madlax is the titular heroine of the anime of the same name. She is 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 Burton, 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.

Personality
Madlax is very kind to everyone, sticks her neck out for people she barely knows, and only fights to bring an end to the war in Gazth-Sonika. A perfect example of this is when she's hired to publicly assassinate the commander of Gazth-Sonika's armies, Guen McNichol. When she's told that the target was also the person who commissioned the hit, she sneaks into his residence at night and, after discerning his motives, comforts him before leaving. However, she is still a mercenary (considered to be the very best in Gazth-Sonika) who kills hundreds without really batting an eye.

She shows some interest in a couple of men, and then there's her subtext-fueled relationships with Vanessa and Limelda. She also says that she loves Margaret during the final battle, when the true nature of their relationship is revealed.
