Avenger is an anime of 2003. It’s about androids in the future which replaces children. In confess I haven’t seen the anime, but I might try it once. Though here is a description found at from anidb.
Mars has been colonized and is a world where children have been replaced by robot servents known as ‘dolls’. Layla is a skilled fighter with a tragic past who travels about the world. Her companions are Nei, a strange and unique doll with some unknown ties to Layla, and Speedy, who is a doll breeder. The founders of Mars see the trio as a threat to their world, and each time they attack Layla and Nei a bit more of their mysterious past and future is revealed.
