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.

Her name means 'Black Demon'. When hunting at night, KuroiAkuma emits a series of eerie shrieks, screams and screeches at forest entrances to scare her prey and drive them out so she may catch them. She uses very little effort in her hunting as she tends to save her energy to fight in case any other Black dragons are attracted to her hunting cries. KuroiAkuma lives alone in a deep cave in a forest. There is proof she has defended her territory many times, many bones litter the entrance of her cave and the ground and trees surrounding are scorched and blackened.

Although she likes her privacy, she is not cold-hearted or vicious, she simply finds it difficult to socialise with others because of the many attacks upon her home, therefore, she does not trust many.
