I recommend "Take a Demon King as a Pet." This was a female swordswoman and magic novel with a Blood Clan female protagonist. The story was about an otaku who mistakenly led a demon king named Charles to the magic world. The secrets of the continent and the game between the gods were all in it. The female lead was a vampire, and the male lead had two beasts called Xiaotian and Xiaoe. I hope you like my recommendation. Muah ~
