Storm Dragons are the masters of the skies. They are excellent fliers and land only to rest and eat. In addition, they have full control of the weather. They are very hot-tempered and easily angered. They will attack any human that bothers them, conjuring strong winds and dangerous lightning.

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.

Yuki Eiri and Tiki Mikk grew up like brothers, both of them were hot-tempered and easily angered, but still they had a strange sort of power to attract other dragons. Slowly their clan grew bigger and Yuki found his soul mate Kita-chan. After that he became calmer and his hot-tempered attitude showed less and less. Tiki was still alone at that time and therefore Yuki was thrilled to hear that his daughter,Tsume, agreed to have Tiki as her life mate.
