Black Dragons are warriors. They are strong and capable in battles of force, but also ample magic users, capable of devastating opponents with their spells. Their bright eyes give them excellent night vision, which is why they generally hunt during the night.

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 "Black Belt" in Japanese. He is a son of Jiro and Kazumi, who named him after his strong will. As a young hatchling he began to show signs of being a great warrior and leader. He was always coordinating the other youngsters on "Adventuring Parties". Not only that, but he started studying martial arts, and honing his fighting skills and discipline. By the time that he matured he was a master. Now he acts as a defense for the valley, training other dragons to help defend their homes and their lives. But his favorite pastime is teaching young hatchlings the joys of martial arts. That's how he met Kiri, she was babysitting one of her young siblings, and she loved how Yuudansha was so gentle, patient, and caring. Soon they were courting one another, and on a crisp spring morning, they became mates. They are both so in love, and they always will be.
