Madlax is a 26-episode Japanese anime television series produced in 2004 by the Bee Train animation studio. Kōichi Mashimo directed Madlax and the soundtrack was composed by Yuki Kajiura. The DVD version was released by ADV Films in North America and the United Kingdom and by Madman Entertainment in Australia and New Zealand. The story revolves around two young women who seemingly have little in common and do not know of the other's existence at the beginning, and later join forces to investigate a powerful crime syndicate. Madlax was produced as a spiritual successor to the studio's earlier project, Noir, and together with El Cazador de la Bruja, these series constitute a trilogy exploring the "girls-with-guns" genre. The production of Madlax began in 2002 but it wasn’t until Yōsuke Kuroda joined the project that the series took its final form. While the critics noted the resulting similarities between Noir and Madlax, they also acknowledged the differences, such as the latter's less episodic and more plot-driven style and, in particular contrast to the predominantly realistic Noir, incorporation of many supernatural elements, which the audience must often interpret without further explanation.
