The Turn A Gundam and Kapool land on the moon, discovering a giant river. Loran reunites with Donna and Hammett, who ride dolphins, and they visit a home where a crowd welcomes Dianna. Meanwhile, Guin, Michael, and Lily meet Gym, who directs them to Agrippa due to his military focus. Midgard attempts to stab Harry but fails. Dianna aims to reach the Moon capital of Gaingnham via the river. The group crafts giant whale disguises for the Turn A Gundam and Kapool using cloth. Sweatson’s group arrives on the moon and begins searching. The Aspite and Willghem descend toward Gaingnham. The whale disguises allow Loran and his companions to successfully repel Sweatson’s attack.
