She is a level 3 Hydro Hand (水流操作ハイドロハンド, Suiryū Sōsa (Haidoro Hando)?, lit. "Water Current Manipulation") and it is shown to control small amounts of water in a way to form a miniature waterspout.[1]
In her combination battle with Maaya against Baba Yoshio's robots, it is shown that she requires a body of water to use her powers, and once it is scattered on the ground she will not be able to make use of it.[18] Kinuho can only control four separate clumps of water at the same time, though it is shown she has great difficulty for every clump she tries to control. Furthermore, once she controls water, she can still control it despite being out of her sight, or taken inside a container.[19]
