For a vampire, familiars were an extremely important existence!
Aside from their nearly infinite vitality, vampires could only be considered a weak branch among demons, whether in terms of physical strength or combat ability. The reason they were called the strongest of the demon race lay in the overwhelming power of the familiars nurtured in their blood.
Therefore, for every vampire, familiars came first!
Once a vampire was born, the very first thing they did was undoubtedly summon a familiar from another world and raise it in their blood for their own use.
Now, a vampire who was only in his twenties not only possessed an enormous amount of magical power and no familiar, but could also fight two vampires who had unleashed their familiars all by himself! Originally, Nangong Nayue had only appeared there because one of her students had been there and seemed to have run into some trouble. Otherwise, merely detecting abnormal magical power—such a common occurrence—would never have drawn a top-class Demon Slayer like her.
Bringing Wu Yan and Kotori here had merely been out of a desire to protect Akatsuki Nagisa, along with a passing whim.
Now, Nangong Nayue was truly becoming interested in the man before her. No matter how she looked at it, this unusual vampire was covered in inexplicable mysteries. If she could, Nangong Nayue truly wanted to uncover every last one of them.
"What a... unbelievable vampire..." Nangong Nayue made no attempt to hide her curiosity. Her gem-like eyes remained fixed on Wu Yan, as though she intended to see right through him, yet she did not ask outright. Intelligent as Nangong Nayue was, she knew that true secrets would not simply be revealed to her.
As for Wu Yan, being stared at so intently by such an alluring "little girl"
