Red Dragons are similar to typical story book dragons. They shoot flames, can fly, etc. However, they aren’t evil creatures as depicted in myths and won’t go around raiding castles, killing knights, or kidnapping princesses. They live in a variety of habitats, from forests to coastlines to abandoned castles, usually in warm climates, and eat whatever living creatures they can find.

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.

Tsu' is short for Tsunami. A-chana knew that a name with water-related meanings would not work out well for a dragon that kept setting random objects on fire, however, and uses the nickname almost exclusively. Tsu' is extremely emotional, although some of the other dragons joke she has only two moods: Dangerously furious, and obliviously chipper. This isn't to say Tsu' is a bad dragon to be around. Tsu' is the 'little sister' to them all, even though she's older than some. She's loyal to the others, and if the situation ever called for it, she'd give up her life for them. She may act like she hates them sometimes, but in reality, she loves them all dearly. It's her family, after all.
