Synopsis
In the year 2040, Reito Mizuhara is a young man who is put into cryostasis while awaiting for a life-saving treatment to be developed in order to cure the rare disease he suffers. Five years later, Reito awakens to discover that, in this period of time, an extremely lethal and contagious virus called the MK (Man Killer) has emerged, which mysteriously affects only males, causing the death of about 99.9% of the world's male population except for approximately one million survivors who were put into cryostasis before being infected. Much to his surprise, Reito also learns that he is one of five men in Japan who somehow developed immunity to the MK Virus and, as a result, is required to participate in a breeding program by impregnating as many women as possible so that their children can replenish the world's population. While Reito investigates the secrets surrounding the MK Virus and the mysterious disappearance of his childhood friend Elisa Tachibana, the series also shows the perspective of the other men who have developed immunity to the MK Virus, each with their own circumstances.

Reception

Critical response
The series received a mixed reception from critics. While it was praise for its unique approach to the harem genre, it was also criticized for its semi-apocalyptic setting, with many reviewers feeling it "didn't fit the harem format". Maxwell Freedman of Comic Book Resources stated, "The harem genre has long been controversial. Criticism ranges from trashy and repetitive right down to damnable and misogynistic. World's End Harem doesn't do a whole lot to counter these criticisms, but it does have some deceptive depth. As the manga goes on, it becomes increasingly psychological, exploring the dystopian ramifications of a female-only future instead of simply glorifying it as a male paradise. This doesn't change the fact that the majority of the manga's appeal is, of course, in the fanservice."
