Horse Dragons have equine-shaped bodies and hooves instead of claws, which allow them to be fast runners. They specialize in running takeoffs, which are quicker than taking off from a stand-still. Horse dragons are able to stalk their prey from the ground then quickly execute an aerial attack for the kill.

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 "Little Gift" in Japanese. She is Eiai's first daughter. Soshina's egg showed up, abandoned in the wilderness, and Eiai was the one to find it. Usually the egg would have been given to a nice couple to raise, but Eiai refused to give the egg up, she'd found it, and she'd raise it, alone if she had to. However, Kanbi, Tabi, Uma, Aiba, Keiba, and Tategami all decided to help Eiai raise the egg, and are now Soshina's aunts. She is a very headstrong and adventurous dragon, and loves to compete. She met her mate, Kenkou, after she twisted her ankle while racing. He healed her, and won her heart. They love each other so much, and always will.
