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.

Ryuka was the first born son in the noble and honorable Dragon family the Aisawa clan

After his formal owner tried to kill him due to his specie, (he did not turn out to be a gold dragon like his mother or a gorgeous alternate Black dragon) and the clan rejected him, denying his existence, Ryuka fell into a deep depression. To worsen the circumstance, his mother had a second child, who ended up being his half sister and paternal aunt at the same time.Shocked and confused, not knowing who to trust, he ultimately ran away from the family and owner hoping to reset his life on a new clean scroll.
