Introducing the children

"One day dad will need to be killed, but I'm not yet ready for that day."

In a world where Vampires have secondary genders to procreate easier and more often, Vanitas happens to procreate with an omega, making dhampir children who have the blood of the blue moon running in their veins. Vanitas learns what it's like to have a family life, even after insisting he had no interest in raising them.

(Saw there was no TCSOV omegaverse story and I decided to make one because I love a nice family dynamics and Omegaverse when done right so here we are.)
