My name is Shen Zhao, and I live in a city that seems perfectly ordinary on the surface. At night, a strange fog seeps through the streets, hiding things that imitate humans and lurk in schools, office buildings, and even homes. Twenty years ago, a great disaster split open a crack in a “Gate” sealed beneath the earth, and whispers from another world began to corrode reality. The government secretly formed the “Night Watch” to suppress the contamination with people gifted with supernatural powers. I was born able to see the threads of truth, and I am the last “Heir of the Enlightened.” Jiang Linxue is the campus belle, as well as the most dangerous obsession-born entity. She remembers dying once ten years ago. We are both putting on an act. She is an undercover agent, and so am I. One day, the principal called us into his office and handed us a blood-red contract: Do you want to learn the truth about your parents’ deaths? The price is to sign your name and become a Night Watcher, neither alive nor dead. Beneath the city, Cthulhu-like tendrils are slowly pulsing. And my sunny smile is nothing but a mask to hide my fear.
