Nyaight of the Living Cat - S01

In the 21st century, humanity's love for cats grew so deep that almost everyone owns one as a pet. But selective breeding produces an extraordinary cat carrying a strange virus. The outbreak, dubbed the Nyandemic, turns any human who comes into contact with an infected feline into a cat themselves. Kunagi, a man who has lost all of his memories, is forced to flee mid-shift from a cat cafe. With him are the siblings who run the place, Gaku and Kaoru, and a customer named Tanishi. But Gaku confesses that he is already infected and begs Kunagi to protect his sister. After seeing the danger for themselves, the remaining three begin searching for a way to survive the very animals they adore. Despite the government's best efforts to stop the feline hordes, the Nyandemic spreads uncontrollably. Human extinction seems more likely by the hour, but Kunagi, Kaoru, and Tanishi refuse to give up their humanity without a fight!
