Seasonal Dragons take on the characteristics of the season during which they are born. Thus, eggs that are laid in spring match the pink flowers and green buds of spring, and those that are laid in the summer grow to depict the bright green of the forest trees and the yellow of the sun. Eggs laid in autumn display the bright colors of leaves falling from trees, and those that are laid during winter take on the appearance of the icy snow.

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.

Summer Sun loves to live up to her name. She spends almost all her time sunbathing in the summer sun. She doesn't really socialize with the other dragons very well though. She's always been the quiet type. Though she has kids of her own, she doesn't keep in touch with them. She'd rather just sunbathe without a care in the world. This irks her master, Miroku-Kun, but he knows better than to mess with her. She can be grouchy at times.
