Moonstone Dragons are named after the orb on their tails, which resembles the gem of the same name. They are nocturnal and gather energy through the absorption of moonlight with their orbs. They seem to glow with a lunar light and are a very gentle breed, feeding off of plants and the moons’ power.

Dragons are highly-intelligent reptilian creatures that—from a human perspective, at least—appear to live forever. Many different varieties of dragon exist, each with their own unique qualities, habitats, and behavior. Adolescence in dragons is usually marked by the growth of a hatchling’s wings, although not all breeds of dragons grow wings and some breeds have other traits that indicate the beginning of maturation. In Galsreim, dragons and humans coexist peacefully.

An enthusiastic dragon, Sayaka is the leader of the Ouendan Clan's Cheer Girls division. She teaches yoga in her spare time and excels at mind concentration. Speaking of mind stuff, she is known to discipline the other Ouendan Clan members with mind training. However, she often feels like she's the only one of the cheer girls who actually focuses on helping people.
