Sunset Dragons are closely related to sunrise dragons. However, their behaviors differ greatly. Sunset Dragons generally live alone or in small packs. They are more active in the evening, hunting and performing all of their daily tasks as the sun sets.

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 "Sunset". She is one of the many daughters of Kentaro and Kiyomi, and was raised in one of their largest clutches ever. She was raised alongside her sisters Yuubae, Asayake, Dori-Mu, and Ichimu; her brothers Suto-Mu and Biribiri; and her younger brothers Baishakunin and Nakoudo. She is an incredibly feisty female, and as a hatchling spent most of her time roughhousing with her brothers. Once she reached adulthood she became an excellent huntress, she also found herself pursued by many of the colony's bachelors. However, she couldn't find a male that measured up. She needed someone strong, brave, adventurous, a true alpha. Then, one day, she discovered that she was completely wrong. That was the day that she met Kurokongouseki, a sweet, kind, and gentle male, and she fell in love. They were soon courting, and at a beautiful sunset ceremony, they became mates. They may be opposites, but they are made for each other. They are in love, and always will be.
