I use meditation to reduce the lewd to 0....I thought that was for good
Oh, right. The lewdness goes up by 1 each time Celica orgasms, so the meditation reduction is not permanent. You can always go back to the hot springs to reduce it again, though. But there's no real reason to reduce Lewdness at the moment, at least as far as I'm aware. All it does is make Celica not cover herself up in battles when stripped if it's high enough.
