The background of Grips war.

In 0084 AD, the "Dilaz Rebellion" initiated by the remnants of Jean Principality ended. However, the rule of the federal government is still extremely unstable. After the federal parliament issued a policy resolution to maintain the status quo of the earth circle, the voice of opposition became louder and louder. Although under the iron fist of the Titan Rangers led by Brigadier General Demitov Haimen, there has not been a large-scale conflict in the earth circle, the tension in the air is close to the critical point. In the same year, after the Axis countries were silent for a long time, char aznable, the man of the year's war, secretly returned to the earth circle, which few people knew. He assumed the alias of Quattro Bajeena, and skillfully obtained the army status of the Union Army through illegal means, and became the subordinate of Brigadier General Rieks Forer who opposed Titan's violent means and hoped to fight for human rights for space immigrants.

In 0085, the Titans fought violence with violence, and Mitov, the Brigadier General, won a high position in the federal army. However, Mitov didn't stop there. On the contrary, he intensified his efforts, further conniving at the Titan's more severe suppression-or cruel suppression-of all dissatisfied people. Finally, on July 3 1, the "Satellite 30 Incident" occurred: Commander Basque Om of Titan injected toxic G3 gas into colonial satellite 30, which was the most concentrated protest against tyranny in SIDE2, resulting in millions of deaths. The "30 Satellite Incident" wrote the darkest chapter of Titan's atrocities.

When the news came out, it shocked both inside and outside the earth. Brigadier General Briks finally made up his mind to call comrades to form an anti-Earth coalition government (abbreviated as A.E.U.G, or even pronounced Ogu).

In the increasingly fierce conflict, let the remnants of the principality rise again and become the new Jean New Zeon. Axis, an old mining base in the asteroid belt between Jupiter and Mars, was rebuilt by the remnants of the old Jean Principality for several years, and its scale and military strength should not be underestimated. Under the order of girl commander Haman Kahn, it began to March into the earth circle in February, 0086.
