Daydream Dragons are the hosts of daydreams and fantasies. They spend the majority of their time sitting on clouds, dropping daydreams down into the minds of people passing by. Humans who live near Daydream Dragons must be especially careful not to let their thoughts wander, or they could end up spending hours or even days in a trance-like waking dream state.

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.

Aoi spends most her time with her mate Truffles. She sometimes thinks that Truffles has a Napoleonic Complex due to his size, but doesn't usually mention it. She loves to play tricks on humans and can usually convince her mate to join in on her fun. She especially likes finding large, fluffy clouds to laze on and nap.

As the eldest of the family, Aoi knows the rest of the family looks to her for guidance and does her best to be an adequate role model. However, all she really wants to do is find a nice fluffy cloud and sleep, so she usually leaves the role of leadership to her mate Truffles.
