The short version of my PM is probably this: I love the whole idea and you seem to have thought about everything in a very in-depth manner, and my questions are starting to be more about the KH world than your adaptation in particular. But it all sounds amazing and very involved. And without asking about plot-specific things, which you appear to have planned out fairly conprehensively, despite your lack of idea about the villain, it all sounds perfectly awesome to me.
Oh gosh, sorry. I've been a bit busy the past week, and I haven't really had more time to do anything other than keep up with my RPs and check things and stuff and this sounds like a really lame excuse because it is. Your PMs are too in-depth and interesting for their own good. XD
I'll get back to you soon, but I basically have to go like right now. Sorry!
