Twin sister to Eriya and extremely loyal to Folken Fanel, Naria is of the same race as Merle. When still children, Naria and Eriya’s family experienced prejudice against their race, leading to the death of their parents. The twins were harassed to the point of death and were saved by Folken. Throughout their time spent with him, the two fell deeply in love with the young prince. Just like Jajuka to Dilandau Albatou, the two’s serving Zaibach is due to their loyalty to Folken, and not through their truly believing in the motives of the Kingdom. Through intense training for several years, the two became extremely skilled in several forms of combat, their specialty being Guymelef combat. They were both given the unique Guymelef suit Teiring, a Guymelef specifically designed for high-speed flight and attack missions. The two remained loyal to Folken, carrying out any task he set them to the best of their ability, even if it threatened their very own existence. (Source: Escaflowne Wikia)
