Humans and vampires are at odds, and the era of conflict is reaching its climax.
On a mission to hunt the vampires' leader, the "Primogenitor", a young knight named Fabrice loses consciousness in the midst of retreating from a losing battle. Fabrice wakes to find his enemy, the vampiric Primogenitor herself, waiting for him.

"So many of my people have been killed, and I've got so much free time. It's so boring...so you're going to be our plaything."

What fate awaits Fabrice, the man who'd been kidnapped and imprisoned by his enemy and made into her pet......?!

This is the story of a young man whose whole life had been ruined by a vampire woman.
