Gundam Build Divers Season 1 Episode 5

The next destination for Riku and his friends is the Perisia Area, a neutral zone where builders from all over the world gather, and it is forbidden to bring in Gunpla without permission. As the three of them walk across an endless desert in Diver form, they are eventually confounded by the mirage-filled landscape, which never changes no matter how far they go. Then a jeep appears, driven by a female Diver called Ayame.
