Avenger - S01

Mars has been colonized, and in this world, children have been replaced by robotic servants called "dolls." Layla, a skilled fighter haunted by her past, roams the planet with her companions: Nei, a peculiar doll with unexplained ties to her, and Speedy, a doll breeder. The rulers of Mars view the trio as a danger to their society, and with each confrontation, fragments of Layla and Nei's hidden past-and uncertain future-begin to surface.
