Cyborg Kuro-chan EP28 - The City in the Desert

Still stranded, Kotaro meets a traveller, Fox and her companion Gurnee. They inform Kotaro about the war, which was caused by the two sons of the former king fighting for power, as well as the mystery of a pyramid-like structure known as Taboo. As the group disbanded, Kuro explores the desert and with help from a cyborg named Vice, search around for Nana and Juliet. Romeo is also ordered to take over the role of the older brother who died, so their army isn't overthrown by the other brother.
