I have a few questions. First and foremost you say we have to use real demons yet then link a list of demons from fiction? whats the about?
Secondly is there a plot? or are you going for a jump in and do what you want sandbox?
This is more constructive criticism rather than a question, but the OP is quite daunting. It's a large wall of text with no indication of what your reading followed by a quick section on magic and the rules etc. It might be an idea to tidy it up and put some headers around etc. A bit more organization can draw people in a lot more and hopefully garner more interest.
