My Vampire Family: Sin Dominion

While digging a grave for a co-worker he killed, Levi, a psychopath obsessed with becoming a vampire, meets six-year-old vampire twins claiming to be his biological children. They say their mommy sent them on one mission: to turn Levi into a vampire and help him grow stronger. Now, Levi must navigate a world ruled by blood and sin—where vampires grow stronger by feeding on the corruption within human hearts. Follow Levi and his extraordinary family as they rise in a world where sin is power, blood is currency, and humanity is the greatest weakness. [No harem, may include sexy scenes and a great amount of gore.]
