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.

Even though he has diffrent parents he has taken Water-Diamond as his father and Mary-kun from another scroll as his mother. He is often found with Water-Diamond looking for treasures under the lake. When not with Water-Diamond he's with Mary-kun at the lake shore talking with her and giving her small gifts. He is a very giving person and loves to bring people from one side of the lake to another and is always willing to.
