Usage and Limitations Edit
Her ability is Aquakinesis, she can freely control the shape, density and other things of water. Her favorite attack is where she makes dragon out of water and controls them (maximum 3 at the time). She is able to form a small whirpool, needles and even blades out of highly pressured water.
As opposed to most aquakinesis ability it seems like Mizuki can create water out of nothing (presumably using water vapor in atmosphere). Exact ability range and amount of water Mizuki can create(and/or control) is unknown.
The only weakness is polar opposite ability - Bastet's Claw (fire based ability)
