Beyond the Red Sky
Kudelia and Tekkadan finally leave Mars behind them and head for Earth. With a ship waiting for them, they attempt to travel by shuttle to a low-orbital station but are attacked by Coral's Gjallarhorn forces.
As for Them
The members of Tekkadan need a guide in order to reach Earth despite Gjallarhorn's surveillance. To gain a powerful backer, they attempt to negotiate with Teiwaz, which is based in the Jupiter Sphere.
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.
Mikazuki and Orga learn that Akihiro's long-lost younger brother is one of the Brewers mobile suit pilots. Tekkadan challenges Brewers in order to get back Akihiro's brother.
The battle with Brewers has cost many lives on both sides. The survivors hold a funeral service to pray for the rebirth of their fallen comrades.
Vessel of Hope
After overcoming many difficulties, Tekkadan is finally about to reach Earth. Its members head for the Dort colony cluster to deliver an item Teiwaz asked them to transport when they were aboard the Saisei.
The colony workers have launched a protest movement against the company that employs them. As they grow more radical, the situation develops to the point of a Gjallarhorn intervention. Kudelia has been drawn into the heart of the uprising.
Kudelia and Tekkadan witness Gjallarhorn's brutal suppression of the workers. Seeing the true situation of the colonies, Kudelia makes a fateful decision.
Tekkadan's members attempt to leave the colonies behind and descend to Earth at last but they miss their chance due to one last item of business in the colonies. They are contacted by someone, who claims to be their supporter.
