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.

When Konan's Tsukuyomii was young, he always looked up to the powerful female Magi dragon, Konan's Amaterasu. He was taught to fight, hunt, and respect the dragons and hatchlings of Konan's flock at a young age by the female. As he grew, his feelings for her grew with him. Once his wings grew in, he and Ammy began to fly during the sunsets together and talk about the future, dreams, and wishes. One day, he grew into a powerful Sunset dragon. He earned a lot of respect from the flock leaders, Mistress Konan, Kagihosi the Stone dragon, and Konan's Rose who is Kagihosi's mate and oldest vine dragon. On the evening of his First Hunt ceremony of hunting alone in the pitch black darkness of the forest, he declared Konan's Amaterasu as his mate. Both love each other passionately and they always support each other and the flock.
