Rain doesn't have a particularly special or eyecatching design, I guess. And yes, she was largely inspired by Esmeralda, from Disney's version of Hunchback - she was hawt. Mind you, wild and chaotic gypsy women with a penchant for troublemaking are pretty much always sexy ^_^ It's always very liberating to play a character who knows that society scorns her, and delights in it.

On a side note, I like her tattoo. I think that's a good spot for one. It's so... enticing... >:)
