In response to a decrease in population, human corpses have become a major resource for society's labor pool. Necromancers are needed to animate corpses for various jobs. These corpses work reliably unless they encounter human love, at which point they go berserk and attack.

Zen has a strange assistant, who keeps his face covered and never speaks in public. This assistant is Yomai, a ghoul that Zen took under his wing. Zen allows Yomai to feed from his own flesh, but he has strictly forbidden the ghoul from revealing himself to, speaking to, or eating other humans.
