Entitled "Tenkou no Escaflowne" ("Vision of Escaflowne")
This series follows the journey of Hitomi and Van Fanel as they try to defeat the evil Zaibach Empire with a legendary robotic suit called Escaflowne. Hitomi is originally from Earth, but is transported to a distant world called Gaea. There she encounters Van and his kingdom, and its destruction by the Zaibach Empire. Not having anywhere to go and feeling very alone, she joins Van as he uses the Escaflowne against the evil empire, trying to end their reign and bring peace to his war-torn planet.
