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.
Tekkadan revives and launches an attack, aiming to escape the battlefield. Meanwhile, the fight between McGillis and Gaelio becomes increasingly ferocious.
Tekkadan plans to return to its Martian headquarters and start over. The situation, however, has undergone a dramatic reversal.
Tekkadan is in a difficult predicament. A huge Gjallarhorn force then begins deploying around its Martian headquarters.
Gjallarhorn intends to launch a mopping up operation against Tekkadan as the hour of its commencement is drawing steadily closer.
