In the third year of the apocalypse, the only woman who can eat "Calamity Mist" is hunted across the city as a source of pollution. She keeps eating her way forward until, in the end, she eats the calamity itself.
The Gray Tide arrives, and the "gray snow" blanketing the globe is actually alive. Ninety percent of those infected mutate into "Eroded Ones." A rare few neither die nor transform, becoming Grayfolk: living filters whose bodies constantly seep mist. Anyone who sees them burns them alive. The heroine, Jiang Li, is 24 and used to manage the sample library at the P3 Laboratory. When the Gray Tide struck, she was sealed inside the sample library. On the verge of death, she smashed open an emergency cabinet and injected herself with an unfinished, unnumbered dose of antagonist E-0.
