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.

Ko Kuyo Senshi, meaning Black Night of the Warrior Family, was raised as an orphan by the Senshi family. Though she is mostly known as quiet and polite, Ko is very protective and loyal to her family. Some even say Ko is the strongest among them, as she is known to keep fighting even in vastly unfair situations. Because of her strength and attitude, the Senshi family is very shielding of Ko, and commonly keep an eye on her, lest she get into a fight over her head.
