Mizu Shitataare was a member of the Dark Fall, and she went to earth after Michiru and Kaoru died. Mizu's power was based on water. She created most of her uzaina monsters from something based on water.

Mizu went to earth and went around in many disguises. In just about every episode, Miizu wore a disguise so she can spy on the PreCure girls.

Mizu first appeared in episode 24, and died in episode 32.
