The DX series are compilations of short stories. So far, I can say with pretty good confidence that besides the titular Worship☆Dragon-God Girl, it includes Nekomata☆Ninja Scroll and Maniac's Palace based on the preview quotes. As I don't know enough about the other short stories, I'm not prepared to make any additional guesses as to which others will be included, though there should be 3-4 more short stories based on DX.1.
