Orga, Mikazuki, and their fellow child soldiers have organized themselves into a mercenary group called Tekkadan. Their continuing mission is to escort Kudelia to Earth, where she hopes to negotiate independence for Mars. Thanks to their alliance with Teiwaz, a Jupiter-based crime syndicate, the Tekkadan members have overcome the space pirates—acquiring a second powerful Gundam in the process—and fought their way to the Earth Sphere. Here they will face hidden conspiracies, political intrigue, and the full extent of Gjallarhorn's cruel oppression.
