The year is U.C. 0105, twelve years after Char’s Rebellion. The anti-government organization "Mafty," led by someone called "Mafty Navue Erin," has taken a stand against the corrupt leadership of the Earth Federation. As Mafty carries out terror attacks and assassinates government officials, it gains support from the angry populace.

Mafty's leader is actually Hathaway Noa, the son of war hero Bright Noa. Inspired by the ideals of Amuro Ray and Char Aznable, Hathaway plans to follow in their footsteps and clear a path forward through armed resistance. His destiny, however, is drastically altered as he encounters the Federation officer Kenneth Sleg and a mysterious young beauty named Gigi Andalucia.
