Skywing Dragons spend most of their lives flying in the air. They hunt from the air, diving at prey from above, and land only to rest. They are some of the fastest fliers, capable of extremely high speeds. The webbing at the end of the tail acts as a rudder, allowing them to easily change direction during flight.

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.

A rather calm and collected dragon, until something sets him off, Chiaki seems to be great at everything he touches, whether it's cooking, flying, music, or just about anything you can think of. Especially music, which is Chiaki's "first true love," as some say.

Chiaki loves classical music, and becomes furious when he hears someone playing it poorly, turning into "Devil Chiaki," as Mine has dubbed it, screaming the unsuspecting individual's faults right at them in a harsh and direct manner. Chiaki's harsh criticisms have brought many to tears, though he seems to be slowly softening (though that may be due to the fact that the group he follows has been improving dramatically, lately). His relationship with Mine is strained due to this tendency of his.
