After the Memento Mori's destruction, the Ptolemaios 2 is forced to descend to Earth. The Innovators arrive and attack the ship and in the ensuing battle, Tieria reveals the Seraphim Gundam hidden in Seravee to decisively defeat Bring Stabity. Separated from his comrades, Setsuna is lured by Ali Al-Saachez into a meeting with Ribbons, who reveals that he was responsible for saving Setsuna's life as the 0 Gundam's pilot and influencing Veda to ensure Setsuna would become the Exia's pilot. However, Ribbons now intends to claim the 00 Gundam as his own and has arranged for Al-Saachez to kill Setsuna. In a heated battle between the two, Setsuna manages to destroy the Arche Gundam with the 00 Raiser's Trans-Am system, but is unable to kill Al-Saachez himself when he hears Marina singing with the Katharon children. Meanwhile, tensions between the A-Laws and the Federation Army continue to rise to the point of an emerging coup d'etat.
