Years before the White Base landed on Earth, the seeds of war were planted in a space colony called Side-3. Here the Munzo Empire's great philosopher Chairman Zeon Deikun would prepare a declaration before an assembly of senators, but before finishing his speech would fall victim to a sudden attack on the parliament's dais.

Almost instantly, on the streets, the masses have risen calling for independence and have set protests in front of Earth Federation headquarters on Side-3. The calls for Earthnoids to return to their planet eventually would push the Federation to take up arms hoping to combat these riots. The hostilities pit men versus tanks on the streets of this colony and appear to not be letting up.

Meanwhile, Deikun's family, including his children Artesia and Casval, are soon taken into hiding by a Zeon loyalist - Ramba Ral.
