The Archangel crew crosses the Red Sea to head towards the neutral Orb Union with Cagalli and Ledonir Kisaka on board. With the previous battle weighing heavily on him, Kira talks to Cagalli about his reasons for fighting, making Flay jealous. They are attacked by ZAFT air and underwater type mobile suits, but Kira and Mu manage to take them out.

A battle with ZAFT submarine forces led by Commander Marco Morassim prevents Kira from fighting alongside Mu and Cagalli in their FX-550 Skygraspers. Cagalli's Skygrasper sustains damage and is forced to turn back, but she encounters Athrun's transport plane; her Skygrasper is shot down, but not before shooting down his transport plane, forcing Athrun in his Aegis to eject from the transport plane. By chance, they are both stranded on the same deserted island.

Following the Break the World incident, the story revolves around Sven Cal Payang, a 20-year old male Natural who is a member of the Phantom Pain special forces and pilots the GAT-X105E Strike Noir. It also features Selene McGriff, a 28-year old female Coordinator and a researcher of the "Stargazer Project" for the Deep Space Survey and Development Organization (DSSD).

Sven Cal Bayan and his team are sent to eliminate a Coordinator refugee camp suspected of harboring terrorists. Sven has flashbacks of his military training and conditioning when he was a child. Sven proceeds to massacre the camp without hesitation. In another battle, while defending the Earth Alliance Forces ground carrier, Bonaparte, Mudie Holcroft is killed while fighting ZAFT forces. Meanwhile in space, Selene tests the new AI piloted GSX-401FW Stargazer with its Voiture Lumiere propulsion system.

Phantom Pain attacks the DSSD station to steal the AI data of the Stargazer. The brutal assault leaves many DSSD members and the Verde Buster pilot, Shams Couza, dead. To counter the attack, Selene and Sol launch in the Stargazer and use its unique features to destroy several enemy mobile suits. Lost in space, Selene captures the Strike Noir and uses the Stargazers propulsion system to catapult themselves near Venus. Sven and Selene meet face to face and start their long journey home. Selene administers a drug on both of them to increase the oxygen absorption inside their blood and they slowly enter coma state. They must be found within 27 days or they will die from lack of oxygen, but Sol finds the Stargazer 27 days and 21 hours later.
