Neotropical Dragons are a breed that originate in rainforests. They are fun-loving and enjoy lounging on tree branches, eating whatever fruit they find. They are also often found sunning themselves on rocks, using their large wings to soak up the rays. In the summer, males compete for mates by showing off their striped wings and gliding in spirals down the tree trunks. It is said that the larger the wings, the more likely the male will attract a suitable mate.

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.

Sozoku's name simply means "thief."  She feeds herself by plucking fruits off the trees and by stealing from other dragons she comes across.  However, she vigorously denies laziness, stating simply that stealing is hard work.  Indeed, since she lacks the physical strength to take on most other dragons, she must dart in and fly away with her booty at top speed.  When at a safe distance, she camoflages herself against the foliage until her pursuer gives up the chase.
