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.
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.
A conflict between the rival economic blocs Arbrau and SAU breaks out as their armies clash on the Balfour Plain.
Sovereign of Mars
The fighting ends as the rival economic blocs SAU and Arbrau agree to peace negotiations. As they remember their fallen comrades, the members of Tekkadan decide to withdraw from Earth.
Via a certain matter on Earth, the connection between Tekkadan and McGillis grows even stronger. Meanwhile, the Gundam Vidar, which has been undergoing adjustment by the Arianrhod fleet, finally rolls out.
Tekkadan has discovered a huge object at a mine it is managing. Having received a message from Orga about the object's true nature, McGillis decides to pay a secret visit to Mars.
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 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.
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.
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.
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.
A Future Reward
Orga and the other Tekkadan members have finally reached Edmonton but they are attacked by Gjallarhorn, which seeks to prevent Makanai from making it to the parliamentary session.
