Split Dragons use their sharp teeth and wings to hunt large animals and rarely eat plants. They are intelligent dragons who enjoy mental challenges, preferably alone; Split Dragons are normally solitary except during mating season. When mating, many dragons come together in a group to raise their eggs and hatchlings. These groups tend to be very noisy—reminiscent of a thunderstorm—and last only until the hatchlings are capable of surviving on their own.

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.

Two-headed dragons are unique enough to deserve a separate classification from ordinary dragons. They have two necks, two brains, two mouths, but one stomach and one main body. The two heads usually work together, but there are times when they will fight each other, snapping back and forth. Their unique anatomy prevents them from breeding with single-headed dragons.

Kikuri is obsessed with finding herself a strong mate and father for her children. She has tried numerous times to seduce Kohryu and becomes enraged when he prefers to spend time with his birds than with her. Each of her two heads blames the other for not succeeding in ensnaring him, meaning that of all the two headed dragons in the family, she is the one that fights with herself the most. Sometimes, neither head will speak to the other one for days. <br/>When she isn't trying her luck with Kohryu, she practises her charms on some of the other males, but she would never accept one of them for a mate, as they have only one head each. <br/>Kikuri also loves listening to her mother's stories of adventures in far off lands and heroic battles against mighty demons. Though she claims she disapproves that her mother is used mainly as a mode of transport, she is secretly jealous of her mother's lifestyle and often wishes that she could accompany the team too.
