World's End Harem

Reito Mizuhara, a young researcher who has been diagnosed with multiple sclerosis, will be placed in cryosleep until a treatment is discovered. Short on time, Reito makes the decision to say goodbye to his loved ones and disclose his repressed feelings to his childhood sweetheart Erisa Tachibana. Erisa storms in and says she will wait for Reito as he drifts off to sleep and his awareness starts to wane. Reito awakens five years later in a post-apocalyptic world where 99.9% of the male population had been wiped off four years earlier by the "Man-Killer Virus." He is one of a small number of individuals whose therapy for sclerosis has made them immune to this virus. Reito and the other four males have now become priceless resources for humanity, and it is expected that they will conceive as many women as they can. However, Reito is adamant on finding Erisa and will not make love to any other women. Can he maintain his hold on the woman of his dreams when temptations abound?
