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.

Her name means "Deep Snow" in Japanese. She is the daughter of Toshio and Sengen, and is her father's girl for sure. She has been best friends with Yukiko, Hoshiko, and Yuki ever since she can remember. She is a very loving and kind dragon, and has a mischievous side. Many of the dragons in the valley have been hit by one of her snowballs, but no one can stay mad at her for very long. She is very friendly, and is loved by all the other dragons. She loves to playing around, and enjoys telling jokes and stories. All those are reasons why her mate, Hiroyuki, loves her so much. They met when she was playing on a frozen pond; she was so cute he just had to join her. He kind of took her by surprise, and after a good laugh, they decided to meet up the next day. They soon became best friends, and then they fell in love. The day that Hiroyuki asked her to be his mate was one of the happiest days of her life. She agreed, and they're so in love, and always will be.
