Bright-Breasted Wyverns are a breed of dragon easily recognized by their bright red markings. They are a small breed, only the size of a full-grown man. However, they have developed poisonous barbs on their feet to make up for their size. Their coloration is used to warn off potential predators of the danger, and is also used to attract mates. They are very social, and can often be seen preening in large groups.

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.

Nijito takes pride in his bright colors and often likes to show off near other dragons. He isn't the best at flying, but he can use the poison barbs very effectively to make an escape if he's in a pinch. When using the barbs, he aims for weak points, like the neck or eyes.

He tends to think of himself as more than he really is. At times he does get a bit too far over his head, and has to rely on his friends to help him. One of his best friends is Lakunamo, as they have known each other since they were hatchlings.
