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 "Happy Hero" in Japanese. He is one of the many sons of Kentaro and Kiyomi. He has always been very brave, even when he was a dragonet. He used to go "adventuring" and would often end up in some sort of trouble. Once he managed to sneak away from his mother, and no one could find him. All the other dragons searched for him for hours, and eventually found him chasing lizards at the outskirts of the valley. Needless to say, he was watched like a hawk afterwards. But despite the constant supervision, he still grew up to be an adventurous dragon. He met Seiya during one of his adventures. He saw her playing in the snow, and she looked so much like an angel, he was sure he had died. Once he realized that she was real, and staring right at him, he decided that he had to talk to her. It was love at first sight. They started dating, and then they became mates. They are so happy, and always will be.
