Magi Dragons are, as their name suggests, primarily magic users. They rarely use physical forms of attack. They eat anything they can kill, which is almost everything. They won’t kill unprovoked except when hunting, although they may kill humans if in danger. Their strong magic makes them one of the most feared breeds of dragons.

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 Dxao first arrived at Delirium's Academy the students immediately recognised his exotic behaviour, his politeness, and his unusual—well everything. No one was surprised when he bowed more deeply before Delirium, adressing her with the honorific "Princess" almost none of her students bother with, or when he smiled constantly. After all Yuki Onna had arrived a long time ago and the other Magis recognised familiar patterns, similar looks and accents. Dxao was immediately given quarters next to the renowned senior student so he would feel at home.

Little did they know that Dxao and Yuki originate from completely different cultures which, while influencing each other over the centuries, are age old enemies with a long and rich history of wars and conquering and fighting. None of the long-noses have actually understood to this day that Yuki and Dxao are constantly fighting, insulting each other through compliments, smiles, and very finely attuned bows.
