While gentle as the rain, and violent as the storm blown sea, Mizu is not filled with contradiction. Rather Mizu extends from one extreme to another. Mizu knows no set form, and thus is constantly changing. The water that quenches a thirst can also drown. The Healer knows how to kill.
Mizu is the closest to Uchu, second only to Jimen, for it was Mizu who actually gave birth to Uchu.
Mizu's Hidden form is that of the deepest oceans, and as dark as night.
