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.

Due to her bright red markings and her lethal poison, she is called "Ryuudokusei Bright No Akane", which is Japanese and means "Dragon Poisoned Star, Deep Red of the Bright".

Most of her time, she accompanies with other female dragons of her scroll, hunting and flying together with them. She is rarely seen alone or in the cave during the day.

However, she has a strong distaste to men. Although the reasons are unknown, she hates them to the point of disdain. If a male dragon dares to come close to her, she will not hesitate to use her lethal poison against him.
