In 2040, Reito Mizuhara is put into cryostasis to keep him alive until a treatment is developed that will cure the rare disease he has, and he is forced to leave behind the girl of his dreams, Erisa Tachibana. He awakes five years later to learn that the world has been ravaged by the MK (Man-Killer) Virus which has killed almost every male on the planet save for a handful that were put into cryostasis. He and four others are the only remaining men in Japan who somehow developed an immunity to the virus. Now the planet’s most precious resource, he gets to live the harem dream as part of a project to impregnate as many women as possible to ensure the survival of the human race! But all he really wants is to find Erisa who went missing three years prior. Can true love bloom in an apocalyptic world or will he fall to temptation?
