Hello, MarySunshine23! I would absolutely like to read it. It's an honor if the game was able to inspire you at all. Whenever you finish it, please feel free to e-mail us it at poisonappletales(at)gmail(dot)com. We'll happily look forward to it.
Oh, and I've never heard of Demon Diary before, but if I've nailed the manga art style, then I will certainly take that as a compliment. :)
