A delegation from the lunar forces is heading to the Capital Tower to state their demands. Faced with a common enemy the Space Pirates, the Capitol Guard and Captain Mask join into an uneasy allience. Raraiya seems to calm down when she recognizes a house inside the Capital Tower. The allied forces decide to head to the far side of the moon to investigate the origin of the Lunar colony and the danger it represents.
The Amerian army fleet engage the Capital Army in battle. After withdrawal of the Capital Army forces, the Amerians quietly take over control over the top of the Capital Tower. However, unknown forces from the Lunar orbit attack and destroy one of the Amerian Army ships.
With both the Capital Army and the Amerian Army greatly boosting their space forces as well as the perceived threat from the moon, a space war is brewing. A squad of mobile suits from the Capital spaceship Garanden, led by Mask, sorties to attack the Megafauna in space, but was fended off by Bellri and the G-Self.
The Megafauna makes an under the radar approach to Capitol City to start a dialog between the two parties. A short fight between the mobile suit with Mask and Bellri in G-Selff ends in another loss for Mask. After hiding the Megafauna in the Jungle a small unarmed sortie group departs for Capital City.
The Universal Century, a history marked by space colonization and space warfare, has passed. Humanity's prosperity, which ushered in a new era known as Regild Century (R.C.), was believed to endure alongside global peace. Bellri Zenam, a pilot in training of the Capitol Guard is somehow chosen by the G-Self - a highly maneuverable Mobile Suit of unknown origin - to lead to uncover hidden truths that will shake the peace of the Regild Century era.
