Event Year: 2014

Inaho and the others are hard pressed in their fight against the Martian Kataphraktos. But then a mysterious fighter craft appears and joins the battle. Elsewhere, Darzana and her crew hide the damaged assault ship in a dock, and there, they discover a combat mecha of unknown origin.

Rayregalia, ruler of Mars, orders that an investigation be conducted on Earth. Slaine takes advantage of this opportunity to speak with the Martian emperor in person. Elsewhere, the assault landing ship that Inaho and the others are aboard has been sailing on a course to reach United Earth HQ.

Slain has misgivings about the war. However, he has no allies around him and no way of telling who the enemy is. Meanwhile, Inaho is entrusted with a secret request by Seylum as Rayet, who is hiding her own true identity, is on edge.

To complete his plan, the Mars Knight relentlessly pursues Inaho and the others. Inaho is suspicious about the manner in which that knight fights. With backing from Marito’s group, Inaho begins a counteroffensive. Meanwhile, Slaine, unaware of the truth, has been ordered to provide support for the Mars Knight and is out in the field with him.
