Royal Crimson Dragons are so named due to their massive size and confident, regal bearing. Most of the time they are laid back, ignoring non-prey creatures smaller than themselves, although they will occasionally take fresh kills from other dragons as a reminder of their place in the social order. Although there are few other dragons large enough to pose a threat to Royal Crimsons, they have little tolerance for potential rivals and will fiercely defend their territory from such intruders.

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.

Giroro is a dragon who comes from a land far away, and before he came to the Kara pack, his friends believed he would be the Magma of the Kara prophecy, though when he turned out to be a Crimson that rumor was immediately put to a stop- as he had been in a different form in that other land. Seemingly tough and solitary though actually a kind soul, the warrior waits for the others of the prophecy, and is delighted to be reunited with his friends from that other world. He has also been reunited with the love of his life, his "warrior princess" Natsumi. They are now mates. Although he is not part of the Kara prophecy and she is, he loves Natsumi unconditionally.
