Albino Dragons are so named because their translucent, scale-less skin lacks all pigment. Instead, to help protect their bodies from the sun, they are coated in an oily secretion that blocks the sun’s harmful rays. The call of an albino dragon is similar to a barn owl--a shriek instead of a roar.

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.

Iruma is the second son of the proud white dragon Sugumi Takahashi. Despite still being descended from both the honourable Takahashi and Vulcanord bloodlines, others of his family look down on him for the circumstances of his birth. After his father's arranged mating to Leiko Merum-D'Hennegel produced an heir, Sugumi chose to live instead with the female he loved, the albino Kichouna Syn, who was of common birth. And thus was born Iruma.

Being stubborn and willful, Iruma has refused to have anything to do with his father's family, and he and his brother hate each other. When he met the nebula Porrima Zodiac, he fell in love and moved into her family's living area. He now only keeps regular contact with his mother, and occasionally his father. But whenever he and his brother meet, the usually placid dragons end up shouting at each other until someone else intervenes and separates them.
