Sea Battle Under the Moon
The Turn A Gundam and Kapool enter the moon. There they find a giant river and Loran meets up with his friends Donna and Hammett, who ride dolphins. They head to their house, where a crowd is excited to see Dianna. Guin, Michael and Lily meet with Gym, who says that he's more focused on the military and they should speak with Agrippa. Midgard tries to stab Harry, to no avail. Dianna hopes to head to the Moon capital of Gaingnham and they wonder if they can get there via the river. Working with cloth, giant disguises are made for the Turn A Gundam and Kapool to make them look like whales. Sweatson's group arrives at the Moon and starts searching for them. The Aspite and Willghem descend to Gaingnham. Whales appear, enabling Loran and the others to repel Sweatson's attack.

Turn A Gundam
This story is set thousands of years in the future. The people of Earth have forgotten the space wars of the past, reverting back to a pre-industrial existence. But the lunar settlers known as the Moonrace, who have retained their high technology, now plan to seize their mother planet for themselves. As the war of the worlds begins, a young Moonrace citizen named Loran Cehack, pilot of the legendary Turn A Gundam, struggles to bridge the gap between humanity's long-separated branches.
