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.
Battle Before Dawn
Deploying all the fighting strength it possibly can, Tekkadan attempts to capture Sandoval Reuters, the leader of the Dawn Horizon Corps, with help from Gjallarhorn's outer lunar orbit joint fleet, Arianrhod.
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.
A conflict between the rival economic blocs Arbrau and SAU breaks out as their armies clash on the Balfour Plain.
Gjallarhorn has received a mediation request from the SAU. In order to break the prolonged stalemate, McGillis personally enters the battlefield in a mobile suit.
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.
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.
Trail of Footprints
Just as on Mars, the colonies suffer great disparities with Earth and a protest movement has begun among the increasingly dissatisfied workers. As it gradually intensifies, Tekkadan is caught up in various schemes.
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.
Tekkadan has finally made it to Earth successfully introducing Kudelia to Arbrau's representative, Makanai Togonosuke. However, they will have to accompany Makanai to a parliamentary general session taking place in Edmonton.
To the Place of Return
During preparations to depart for Edmonton, Tekkadan finds itself under attack by Gjallarhorn. Setting a trap for their relentless pursuers, Orga makes a counterattack.
