Waterhorse Dragons received their name due to their horse-like physique and endearing behavior. They are capable of surviving out of water, and when on land their skin secretes a gelatinous goo to retain moisture. However, their large paddle feet are better suited for swimming, and waterhorse dragons tend to move very awkwardly when on land. Waterhorses are very friendly dragons and enjoy playing with humans.

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 "True Brightness" in Japanese. He is the son of Akio and Sazanami, and always loved playing in puddles with his mother. He is a total mama's boy, and to this day likes to visit her as often as possible. He is very sweet and timid, but he loves to hang out with the other dragons. When he met Tsukiko he knew that she was the one worth fighting for. So he overcame his shyness and asked her out. They began courting, and fell in love with each other. Before he knew it, he blurted out that he wanted to be with her forever. They became mates, and know that they will love each other forever.
