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.

Yuuki-Yuki is named so because in Japanese "Yuu" means gentle and "Ki" means princess. And "Yuki" means snow. So all together, Yuuki-Yuki's name means "Gentle princess Snow".

Her owner decided it would be the perfect name seeing she grew up to be a pacifist dragon, capable of great healing but never harming. And she was also as white as snow.

Yuuki-Yuki is the first female offspring of four generations straight being pacifist Dragons. The past three, her Father, Grandfather and Great-Grandfather (F4G4), have all been males.

Yuuki-Yuki, of course a vegetarian loves to eat fruit as she has a sweet tooth, but she also enjoys other dishes like Vegetable soup and Vegetarian nachos. Yuuki-Yuki is very tame and true to her name, she is very gentle towards other people, animals and dragons. But if something brasses her off, then she just squeals her frustration but never really snaps.

She has never found the need to fight with anyone or dragon because as a pacifist, she always has ways around it.
