Diabolik lovers- Great Bloodlines

My Grandfather told me that the Vampire world was built mostly on bloodlines, the most powerful of them all was the Petrova line which begun with a girl named Katara Petrova she was the first vampire in existance and when she was just an innocent beautiful girl a man left her at the edge of death a witch helped her heal with the curse of feeding on other people she had two children and left them behind to carry on the line of vampires everyone knew that she had immense powers which carried through our line.
