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.

Yoyu Honoo Atsuihono, meaning Molten Flames of the Hot Flame family, is a hot and spicy dragon, with a bright personality and a fiery temper. He is quick to learn bad manners but knows how to act polite. He will always speak his mind and is quick to stick up for his friends if someone picks on them. However he isn't too great friend other wise and thus doesn't have many friends. He is particularly fond of Nyusatsu and her soft personality.
