Ten years ago, Eriya’s and Naria’s parents were killed due to prejudice against their race, and thus the two were bullied for meaningless reasons until they faced death itself. When in that position, the sisters were saved by Folken, and throughout their time spent with him, the two fell deeply in love with him. 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. After which, the two presumed their loyalty to Folken, carrying out any task he set them to the best of their ability, even if it threatened their very own existence.
- Eriya is the younger of the two twins.
- Her original name, before being rechristened by Folken, was Belubelu.
