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.

His name means "Sharp, big boy" in Japanese. He is one of the original three dragons to settle in Ryuu Tanima, the Dragon Valley. He is a proud dragon, and fiercely protective of his mate and offspring, although he has curbed most of his more violent tendencies in order to please Kiyomi. Kiyomi is the love of his life, even though they don't agree about everything. He loved her since they were children, and soon enough, she loved him as well. They now have many biological children, even more adoptive children, and their family continues to grow. He is pretty much the father of the valley, and takes in any eggs or hatchlings from the wilderness that are unclaimed. Kentaro is in charge of keeping the peace in Ryuu Tanima, since he is older than most of the other dragons, and they all respect him. He may not be the biggest dragon in the valley, but all the other dragons treat him as their leader.
