Unlucky Rhine accidentally boards the same train home as the True Ancestor. After an explosion at a celebration, the only one left at the scene is a newly born vampire princess.
When she learns that the only way to fully awaken is to drink her little sister's blood, Rhine, a doting big sister, can't accept it. She decisively joins the forces of good and becomes everyone's favorite.
And so, in a rather large room...
A certain vampire expert pushes up her glasses. "So, that means your bloodline is exceptionally pure?"
"Of course! I'm at least the eighth king of the vampire race, so of course it's pure!" A certain tipsy vampire princess gives herself a thumbs-up.
"Excellent." The vampire expert pats the vampire princess on the thigh. "Then show me just how pure you are."
"What do you mean, show you? What are you going to do?"
"Be good and let me have a look." The vampire expert steps closer, only to be pushed back by the vampire princess.
"N-no, don't!"
So the expert takes off her glasses and gives a wicked smile.
