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.

The Mars Knights have assembled at Marineros Island. Slaine tries to take part in the battle, but he is looked down upon by his erstwhile fellow knights because he was born on Earth. Elsewhere, the crew of the Deucalion prepares for battle at Trident Base. Learning of the existence of Slaine’s swift Tharsis, they are wary of its capabilities.
