Hellfire Wyverns are so named for their foul tempers and fiery visages. Their social structure places all females above all males, due to superior physical characteristics and violent dispositions. Forced subservience of the males causes them to become vicious, petty, antisocial, and passive-aggressive compared to the aggressive and social females. However, orphaned hatchlings raised by foster parents of another species can develop surprisingly even tempers and mellow dispositions, proving that their defining unpleasant nature is, in fact, a learned behavior.

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.

She never met her biological parents, and was raised instead by Kiyomi and Kentaro, alongside her sister Kin'ai. Since she was raised in a loving, and non-violent home, she didn't develop the nasty temperament that hellfire wyverns are notorious for. Her mother decided to name her Hanabi, which means "Fireworks" in Japanese, since she has such beautiful fiery markings. She has a strong personality and can be competitive, but she is NOT aggressive. She is however, extremely social, and likes to hang out with the other female dragons whenever possible. She also likes to laze around with her mate Shin'ichi, whom she loves very much.
