Makanai has retaken his position as Prime Minister of Arbrau while Tekkadan becomes a formal member of Teiwaz after obtaining rights to half-metal. In addition, Tekkadan is now the official military advisor for Arbrau. Kudelia and Teiwaz form the Admoss Company to mine, process, and ship the half-metal of Arbrau colonies. She also opens an orphanage at the Sakura Farm on Mars. At the same time, the exposure of Gjallarhorn's corruption has caused a mass instability in the Outer Colonies, with more Mobile Suits and Human Debris appearing on the scene. Tekkadan is assigned to escort the Admoss Company on a tour of their mines. There, the new recruits and the Gundam Barbatos Lupus are put to the test against a large pirate faction known as the Dawn Horizon Corps, who have been hired by President Allium Gyojan of Terra Liberionis in retaliation for Kudelia rejecting his bid to use her influence.
