Synopsis：Eighteen years after a nuclear war, the surface is toxic and men are nearly extinct. Nate lives in a sealed bunker with three women who raised him: Vamira the vampire, Zena the zombie nurse, and Seraphina the lamia. Once he comes of age, their “health checks” turn out to be breeding evaluations—his score appears on a screen, and the three agree that whoever reaches 100% first will earn the right to be his partner and carry the next generation.
