Lunar Wars World

In the year 2087, when a military force called the Lunar Empire of Giganos has risen and captured the Moon. Their stated goal is the rebirth of mankind, but their primary intention by some of its members is the destruction of all those who dwell on Earth.

Setting

The year is 2087, and mankind has started expanding into outer space, founding colonies on the Moon and advancing dramatically in technology and generally improving the living conditions for everyone. However, a dark shadow is cast over this future, as the Moon colonies, under the leadership of Marshall Iskandar Guiltorre, declare themselves independent under the collective name of Giganos Empire.

After years of excalating tensions, brought on by the ever-growing discrimination against Earthlings on the Moon colonies, and by the construction of Giganos' Mass Driver, war finally breaks out, with Giganos Empire in an overwhelming advantage thanks to its technological superiority and the use of anthropomorphic Humongous Mecha called Metal Armors. A few months in the conflict, already 70% of Earth is under Giganos' dictatorship, and the Earth Federation is getting desperate...

Fortunately for the Federation, three new-model Metal Armors codenamed Dragonar are captured by an Allied fleet during transportation. Unfortunately, the Giganos forces immediately start pursuit, with the order of taking them back at all costs... and in the whole mess, the Dragonar end up being boarded and piloted by three teenagers from the neutral colony of Arcadia, which Giganos attacked to take back their prototypes.
