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.

Daimaru Cheng, son of Daidaiiro Heart and Dai Cheng of Sarunikae's clan, is a naive young dragon. He is very timid and hard to get near, like his mother. Nonetheless, he is a great leader, and when he was young, he saved the frozen hatchlings from an enemy clan's adult dragon, Iceleon. Daimaru gets this trait of leadership from his father. Daimaru spends his days mostly taking care of the young ones of the clan, and welcoming newcomers; his favorite friends in the clan are the new autumns Akikaru and Kyoko.
