An international terror network has begun a campaign of bombing attacks in order to force Celestial Being to halt its armed interventions.

Four months have now passed since Celestial Being began its armed interventions. The initial chaos has subsided, and life goes on.

In Earth orbit, Sergei's mobile suit team continues its attack on the Ptolemaios and the Gundam Meisters. While Setsuna and Lockon defend their mothership, Allelujah and Tieria find themselves caught in the enemy's trap.

The Ptolemaios crew return to space for a rendezvous with Team Trinity. When they finally meet the new Gundam Meisters face to face, Setsuna and his comrades are disturbed by their attitude and behavior.

Team Trinity continues its campaign of armed intervention. Unlike Setsuna and his comrades, they are targeting military facilities of all kinds and exterminating everyone on the scene, even civilians.

Alejandro Corner and Ribbons Almark have forced their way into the heart of Veda and taken control of Celestial Being's master computer. But their actions have triggered an unexpected programmed response.

The Celestial Being mothership Ptolemaios has been destroyed, and most of the Gundams are beyond repair. Yet Setsuna continues his desperate fight against the overwhelming power of Alejandro Corner's mobile armor and the final weapon hidden within it.

Having been rescued from near defeat by the Katharon resistance group, the Ptolemaios 2 now takes refuge at a Katharon base in the Arabian desert.

The Katharon base has been devastated by the A-LAWS attack. The words of a dying soldier remind Sumeragi of a traumatic incident from her past, and she passes out.

Sumeragi has regained consciousness, and thanks to her tactical plan the Ptolemaios 2 is able to escape the battlefield. However, Allelujah's Gundam has been shot down along with Soma Peries, and his comrades cannot locate him.

Tieria is shocked at the sudden appearance of his lookalike Regene Regetta. He is further disturbed by Regene's revelations about the Innovators.

The Ptolemaios 2, damaged by the Innovators' attack, descends to Earth. Now separated from his comrades, Setsuna searches for the Ptolemaios 2. But instead, he finds Ali al-Saachez and his Arche Gundam waiting for him.

The Ptolemaios 2 has received supplies from Katharon, and repairs are now in progress. But it cannot break through the Federation's siege without the fighting strength of the 00, and Setsuna has not yet returned to the ship.

The A-LAWS have abruptly retreated after receiving word of a coup d'etat within the Federation. Hoping to reunite with his comrades, Setsuna sets the 00 on a course for Africa.
