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.
While on patrol, Akihiro and Takaki encounter unknown enemies and engage them in battle. The attackers turn out to be Brewers, a pirate group that operates between Mars and Earth.
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.
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.
The Gravity of Wishes
With its path blocked by Gjallarhorn's fleet, Tekkadan attempts to descend to Earth in response to Kudelia's request. The battle against Gjallarhorn soon becomes very fierce.
Mikazuki's group, Tekkadan, has been commissioned to escort Kudelia on an inspection of a halfmetal mine, but suddenly, finds itself under attack by space pirates.
In the Midst of Jealousy
Despite some casualties, Tekkadan has successfully repulsed the space pirates of the Dawn Horizon Corps. It appears, however, that this enemy was just one part of a huge space pirate group.
The Trigger of Success
Mikazuki and Orga visit Allium, leader of the ideological group Terra Liberionis, to resolve the issues surrounding the attacks of the Dawn Horizon Corps.
Inauguration of the Arbrau Defense Forces
Tekkadan's Earth branch, which is now serving as a military advisor to Arbrau, is consumed with preparing the launch ceremony for the Arbrau Defense Forces. At Makanai's request, Tekkadan takes charge of security for the ceremony venue.
