It's an incredibly good idea...but honestly, it's one I kinda want to keep to myself? It's not something I'd ever be able to make. (I'm not skilled enough at making a mangaesque art with the level of detail necessary especially in a lite-high-fantasy setting. Especially not one where being anatomically accurate holds plot relevance and I can't draw people properly proportioned. Also there's the whole, "It's basically porn with plot" premise to it.)
It's a really good idea, though, one I find hilarious, cute, endearing, and yet disturbing, the perfect mixture of twisted messed-up stuff and absolute slapstick carefree lightheartedness. It's just a story idea that I want to enjoy by myself, more or less, to have as something to run my head through "reading".
I even completed the first chapter start to finish, and have an idea of many key events happening in it, along with no less than three possible endings (which one, I favor in spite of it being by far the most cliched of them, simply because there's a sense of poetry to it).
