Iron and Blood
Mikazuki belongs to the private security company CGS at the Martian city of Chryse, which has been hired to escort Kudelia to Earth. But just as preparations for departure are underway, Gjallarhorn attacks CGS in an attempt on Kudelia's life.
The adults of CGS flee in the face of Gjallarhorn's attack, using Mikazuki and the other children as decoys. Gathering the children who have been left behind, Orga decides to fight back against Gjallarhorn and puts a certain plan into motion.
Thanks to Mikazuki and the Gundam Barbatos, Orga's group has temporarily repulsed Gjallarhorn, though not without many sacrifices. As they are discussing their next move, one of Gjallarhorn's Graze mobile suits again appears at the CGS base.
The Price of Life
Kudelia is distressed so many boys have lost their lives because of her. Mikazuki takes her to the farm run by Biscuit's grandmother, where an unexpected encounter awaits.
Tekkadan has made contact with Turbines, which runs Teiwaz's transport division. But they find themselves clashing with Turbines over their group's origins and property.
The Form of Closeness
Having demonstrated Tekkadan's strength and legitimacy to Naze, the leader of Turbines, Orga and the others renew their negotiations with Teiwaz. Meanwhile, Atra visits Turbines's warship bringing the frustrated Kudelia with her.
Accompanied by Naze, Tekkadan visits the Saisei, the stronghold of Teiwaz, in order to meet with Teiwaz's representative McMurdo Barriston. Here, Orga receives a surprising proposal from Naze.
A Letter from Tomorrow
Tekkadan and Turbines go on ahead to Earth, leaving Mikazuki and Yukinojo on the Saisei to complete final adjustments to the Barbatos. But the events aboard the Saisei have greatly affected their respective states of mind.
