Sousei Kishi Gaiarth

Long after a devastating war, humanity survives among lost technologies and combat machines that still roam the land. Ital grows up under the protection of the aging war-roid Randis until an attack destroys their isolated life and takes his guardian from him.

Traveling across Gaiarth, Ital joins the amnesiac robot Zaxon and the junk hunter Sahari. Their encounters reveal that the weapons of the past are more than abandoned relics, and that a deeper threat may endanger the fragile civilization rebuilding around them.
