Review of chapter 10...the new chapter that feels promising...but also very short. You end with a very good line from Lilith that suggests the upcoming scene will be quite fun, but then the chapter is over.
One thing I thought about as I was reading this was that that the complaint from Lilith brother seem well founded. Her status seem kind of mary suish with benefits but few disadvantages compared to her brother. What is it really that she puts as risk by going around and working at protector of mankind? A random idea from me would be that embracing her horns side and doing such actions as she plan to do the end of chapter 10 bring the risk of temporary or permanently put her status and the powers that comes with them in jeopardy...him giving his secrets can make it more easy for his allys to deal with her.
Quite a few story codes for this story...but after reading the first 9 parts I have not found much content matching the story codes, Kind of a shame really since it seems you have the concepts and characters for making it fly. The style of the story makes me think on Hamiltons Anita Blake books....except for far less actual sex than in Hamiltons books.
Speaking of things to improve...in part 2 you write "bad" instead of "bag". I also think you should consider redoing the intro to more show-instead-of-telling. It is nothing wrong with the intro in itself except that Lilith is too good character for delivering the information as an info-dump.
There was a formatting issue with me in particular. I'm not sure if this is an issue with everyone else but I think the Xs you used to separate the story from the mini prologue is locking the format into an extra wide screen. It could be my desired reading style and my phone clashing. But your story is the only one that appears this way.
I'd suggest just three to five Xs in the center. :)
