Yuki and Marito are reunited with the crew of the Deucalion. Meanwhile in the Vers Empire several Counts are plotting against Slaine, believing him to be unworthy of his new position among them. Count Mazuurek, who was reluctant to engage in battle due to trying to avoid any needless damage to Earth's resources and inhabitants, is ordered to engage enemy forces.

On the lunar base Slaine and Count Marylcian begin their duel, one that Slaine fears he might actually lose. Meanwhile on Earth, things are looking equally grim for the UFE forces who've encountered a Martian Cataphract that uses powerful laser weapons to keep enemy forces at bay.
