White Dragons are pacifists and specialize in extremely strong healing magic. The only limit of this magic is that it can’t bring back the dead. They only eat plants and never kill living things.

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.

Tamayuki is like other dragons of his breed a kind and very calm and caring dragon. He hates to fight physically, but would not hesitate to discuss with other dragons or humans who wants to harm any other being. This White Dragon takes care of the wounded and sick ones of the group and would do everything to heal them. He is quite popular among the other dragons, in fact almost every breed likes him, especially the Black Dragoness Kuronaifu. It appears that there must be a special bond between these to dragons of the cave, because he is always protected by her, if stranger comes by and tries to harm him.

Already when Tamayuki hatched from his egg, he had been around Kuronaifu and she seemed to be fascinated about his white fur, and wings when he slowly matured. Then it happened that Tamayuki fell in love with her and is still protected by Kuronaifu's martial personality.

He also had has a child with Kuronaifu, Feixing Xiaogui, who was turned into a vampire.
