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 Diamond" in Japanese. He is one of the many sons of Kentaro and Kiyomi, and was raised alongside his brothers Tenba and, Sekibutsu, as well as his older brothers Baishakunin and Nakoudo (who had not quite left the nest). He has always been very close to his brothers, and still enjoys hanging out with them whenever possible. Kurokongouseki is a calm and peaceful dragon, preferring a nice relaxing day over one of adventure. He is very fond of poetry, and of singing. Which is why it's so ironic that he fell in love with Iriai, his adopted older sister from another clutch, and a feisty female dragon. There's is a tale of fire and ice, two opposites who happened to attract. They quickly fell in love after a chance meeting in the meadow at sunset. They became mates on a clear spring day, just before nightfall. They are so in love, and always will be. No matter how different they are, they are made for each other.
