As far as I know, you're looking for a novel where the protagonist can summon a 2D girl. I strongly recommend "My 2D Beauty Tenant." The protagonist has the ability to summon 2D characters. He has summoned 2D beauties such as Sister Pao, Furan, and Mother Zi. He has also been to worlds such as Star Dragon Knight and Fantasy Village. In addition, the main character was also of the vampire's ancestral bloodline. I hope you like this fairy's recommendation. Muah ~😗
