Is Avenger coming back?

Avenger ended on December 25, 2003, after its first season aired on TV Tokyo.

It was an action-packed anime series that premiered in October 2003. The show was set on Mars, a colonized world where children had been replaced by robot servants called 'dolls.' The story followed Layla, a skilled fighter with a tragic past, as she traveled the planet. Alongside her were Nei, a mysterious doll with unknown ties to her, and Speedy, a doll breeder. The series explored themes of conflict and identity as the founders of Mars viewed the trio as a threat, leading to attacks that gradually revealed their hidden pasts and possible futures.

The episodes each had a runtime of approximately 30 minutes.
