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. Allelujah and Peries leave their crashed mobile suits and confront each other in person.

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. Meanwhile, Kati Mannequin is horrified by the results of Aber Rindt's ruthless mopping-up operation. Soma Peries is also despondent after witnessing the attack. She receives a message from Sergei Smirnov, but although she appreciates his sympathy, she sees no choice but to accept her role as a super soldier and recommit herself to the battlefield.

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. Resistance leader Klaus Grad offers to join forces with Celestial Being against their common enemy, but the crew are reluctant to ally themselves with Katharon. While Setsuna takes off in a small craft to return Marina to Azadistan, Saji takes this opportunity to part ways with Celestial Being. Saji is quickly captured by regular Federation forces under the command of Sergei Smirnov, and reveals the location of the Katharon base. When this information is passed on to the A-LAWS, they launch a ruthless mopping-up operation, and the warriors of both sides are horrified by the results.

Setsuna and his comrades have successfully overpowered the A-LAWS and freed Allelujah and Marina from the Federation's detention center. When Marina asks them to return her to Azadistan, they set a course back to the Middle East. But the A-LAWS have anticipated this course of action as well, and they are already deploying a powerful new mobile armor to ambush the Ptolemaios 2 in the Arabian Sea. As the two sides prepare for battle, their members are becoming aware of their connections to the enemy. Allelujah is convinced that Soma Peries, whom he met at the detention center, is his childhood friend Marie. Kati Mannequin, meanwhile, has begun to suspect the true identity of Celestial Being's tactical forecaster. And Billy Katagiri, whose love for his old friend Sumeragi has now turned to bitter hatred, makes a fateful decision.

The A-LAWS prepare a new trap for the reborn Celestial Being at a detention center for anti-government elements. This detention center holds the former Gundam Meister Allelujah Haptism, and the A-LAWS anticipate that Celestial Being will attempt to rescue their former comrade. Among the other prisoners is Marina Ismail, princess of Azadistan, who has her own connection to Celestial Being. In space, the Ptolemaios 2 crew learn of Allelujah's whereabouts, and ask the reluctant Sumeragi to draft a rescue mission plan. As the ship plunges down into the atmosphere to carry out a daring five-minute raid on the detention center, the Gundam Meisters of the reborn Celestial Being prepare for their first battle as a genuine team.
