Dragons are creatures with nearly unlimited life spans. They can survive for long periods of time, and no one has found a dragon that has died of old age. Adolescence 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. Once they hit adolescence, hatchlings change quickly, maturing to their full forms in only 2 years.

Dragons don't communicate with each other verbally, but they will growl to scare off predators and frighten prey. Young dragons will emit an extremely high-pitched squeal when they are frightened. To communicate, they use telepathy with each other and to speak to other creatures.

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.

This black dragon grew up greatly admiring the clan fighter Kurokaze. She wanted to be just like him, even going as far as to half copy his name. (However, her name means 'black shadow', unlike his, which means 'black wind'.) Nothing made her more excited when Kurokaze decided to take the young black dragon under apprenticeship, but she quickly realized just how tough it was to be a fighter. Despite a slap of reality in her face, she refused to give up and learned how to battle efficiently. Now, she is a great fighter who enjoys fighting more than anything, and is also Kurokaze's trusted second in combat. Just like him, she doesn't use magic to fight, but instead relies on her own claws and teeth. Though she isn't as fast as him, she is an excellent flier and uses this to her advantage. She also is taller and heavier, but has found that even now she has yet to win a fight against the master.
