Review Detail of Sevennamed in Deleted Novel

This was one of the best Highschool DxD fanfictions I had ever read, but that all changed at chapter 17. I had rated this story as a "10/10", now it is at best "4/10". I became worried about this story when the author came out with the whole "King of the Jungle Youkai" thing, which makes no sense. But this turned out much worse than I thought. His Mom is a S1ut, Dad is a Devil, has a Half-Devil/Half-Brother. The story has lost all reason and logic.
