Haunted by his past and the ghostly presence of Newtype Quess Paraya, Hathaway Noa joins the terrorist group Mafty under the alias 'Mafty Navue Erin'. With Mafty, he wages war against the Earth Federation government, obtaining the formidable prototype Ξ Gundam which he pilots. Their target: a high-stakes assault on a gathering of top Federation officials in Adelaide, Australia, aiming to influence a pivotal vote and challenge the Federation's authority. Notably, this narrative diverges from the animated adaptation of Char's Counterattack, offering a semi-canonical take on the Universal Century saga.
