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 "Flying Horse" in Japanese. He is one of the many sons of Kentaro and Kiyomi, and was raised alongside his brothers Kurokongouseki and Sekibutsu; as well as his older brothers Baishakunin and Nakoudo. He is a very brave and bold dragon, and loves to compete with others. His favorite activity is to having flying contests, and he is very very good. Like his father, he is a natural-born leader, and helps to defend the colony. He is mated to Yuubae, who he met while patrolling. She is a strong and beautiful female dragon, and quickly stole Tenba's heart. They are soul mates, and are deeply and eternally in love.
