Waterless Control. Ranma 1/2

[Spokavriel]

Looking for fics where Ranma has control over the curse and water is no longer a factor.

[Crescent Pulsar R]

The first story that comes to mind, since I read it fairly recently, is Happi's Redemption. I believe that water is still a factor, for one reason or another (I forgot why), but he does eventually end up with the ability to switch between his male and female forms by willing it.

[Knight of L-sama]

The only one I can think of where water becomes a complete non-issue is Kenko's (aka the author of Girl Days) Paragon.

It takes a while to build up to it but there's also Comes the Cold Dragon by Don Granberry. Water still triggers the change but Ranma figures out a way to control it in addition to water. Warning, some chapters have lime and lemon segments.
