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.

With Tettsui already a dragon, they thought she was safe. Oh no . . . at the second dose of Komui's potions, her seals have been splitting off into dragons of their own! Tenban is one of these seals, and Okuban became one too. Surprisingly, they're not the same type of dragon as Tettsui is, but they do fit their purposes. Tenban as a storm dragon, and Okuban as an earthnature dragon. Tenban apparently had a thing for her accomodator, and took on the 'Bunny' to relate that.
