LOUPS=GAROUS

In a near future, the world's population has decreased dramatically due to a deadly virus that terrorized the whole planet. Now people eat only synthetic food and tend to avoid as much as possible any form of physical connection or "real contact" with living creatures. Real shops have disappeared from the streets, and with the exception of the community centres (what were once called schools), people communicate with each others exclusively online. But even in this tightly controlled and systematized society, there is a group of young girls who actively pursued real contact. And when a string of brutal murders emerges, their challenge to this closed world is just about to begin. (Source: Production I.G.) — Description from AniList community (anilist.co).
