Vampire Overlord's Servant

"Finally you have come back to me, dear, Emilia." A man in an ancient noble suit stood up from the coffin. "This time, you shall love me, only me!" His declaration of love went past the ruined grave and echoed throughout the whole abandoned ancient planet.  It was the last thing Emilia heard before she fainted as the living skeleton cupped her cheeks like a lover. … Emilia, a sub-beta, somehow ended up in the ancient earth after accidentally waking up a skeleton from its grave.  The worst thing was somehow she had become younger and could not communicate with her she-wolf?!  Not only that, somehow she became a slave?! Oh no! What to do?! She was getting sold! Someone, come and help her!
