Bloodivores [Version française]

Also called Time Prisoners, this is based on a Chinese webtoon by Bai Xiao. It's an alternative world where people researched and found the cure for a mysterious sleep-deprivation sickness where people became mad 60 years ago. Those people who were treated are now wearing a black collar who produces a dangerous side-effect: they become vampires. However, this story will take a more grave situation when these vampires/bloodivores start to be menaced by some mysterious Special Forces.
