Storm Dragons are the masters of the skies. They are excellent fliers and land only to rest and eat. In addition, they have full control of the weather. They are very hot-tempered and easily angered. They will attack any human that bothers them, conjuring strong winds and dangerous lightning.

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.

The eggs of the Stormheart clan are only laid during the time the eye of a storm passes over the cave they live in. As a result, Neku and her clanmates have heightened power during storms. Most of her clan will use this heightened power to move the storms to wherever their enemies lie. However, Neku does not like battle, and will usually only use her power to move storms away from the great cave she and the rest of the allied dragons live in.

Her mate is Kaname de la Rosa, but this pairing was forced upon her by the other dragons of the cave, as Kaname was always complaining about being lonely. The other dragons see Neku as a pushover, so she was paired with Kaname for life. She is not entirely displeased with her mate.
