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.

Her name means "To Survive", since she almost died as an egg. She's one of the daughters of Mamosuke and Emi, who took Tasukaru in when she was just a sickly egg. Her shell was too thick, so she couldn't break out properly, and it took far too long for her to hatch. A few more hours and she would have starved in her egg. However, Mamosuke found her egg just in time and helped her out of her shell. She never let her rough entrance into the world set her back though, and she quickly recovered. She is much smaller than most of her kind, likely because of her malnutrition while in her egg. She is a feisty live-for-the-moment dragon. She cherishes every second of her life, and tries to make the most of it. She doesn't have time for fears or insecurities. That's why she asked Yairochou out when he ran into her. He was cute and endearing, and she liked him. They are mates now, and couldn't be happier. They are so in love and always will be. They are on the biggest adventure of their lives.
