When Water Dragons mature, they lose the ability to survive on land, entering the water permanently. They are adept swimmers and eat whatever fish are in the lake they live in. They tend to inhabit the same lake for their entire lives, although a few live in the ocean and swim all over the world.

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.

Nadadorazul is the last of the first four dragons. Her only need and hobby is swimming. She likes the male dragons owned by Banana Queen, but only as friends. Nadadorazul is known as a sea creature who swims in very deep waters, but can pop out any moment she like. She's a bit jealous if she sees any of the other dragons, except from Poderosalapidar and Reyverde, fly. She always wanted to fly too. But she's a waterdragon. She simply can't.
