Plot.
The story is set on a colonized Mars at some unspecified point in the future. The majority of the human population is divided up into a number of small domed city-states. Those who live outside the domes in the harsh wildernesses of the planet are known as Barbaroi. Resources are scarce, and supplies are divided out between cities based on the outcome of gladiatorial battles between representative fighters from each. Adding to the problems of the colonists, no children have been born on Mars for a decade. The cause of the infertility is unknown, but people have turned to robots called dolls as a substitute for the presence of children in their lives. And a red moon, Earth's moon, hangs over Mars, drawn towards the red planet after the destruction of Earth and ravaging it with lunar storms caused by gravitational fluctuations between Mars and its unwelcome satellite.
The protagonist of the story is Layla, a barbaroi gladiator with a mysterious past and follows her quest to defeat Volk, the ruler of Mars. She is accompanied on her journey by Nei, a strange "doll", and Speedy, a doll breeder (or repairman).
Soundtrack.
The music for "Avenger" was composed and performed by Japanese duo Ali Project, which has also contributed music to several, other anime series, including "CLAMP School Detectives", "Noir", "Princess Resurrection" and ".hack//Roots". The series opening Lunar Eclipse Grand Guignol (月蝕グランギニョル Gesshoku Guran Ginyoru) and ending (Mirai no Eve) themes and the score overall are considered by some fans and reviewers to be among the show's most memorable elements. An Original Soundtrack album was released in Japan in 2003.
