World's End Harem - S01

Reito Mizuhara, a medical student at Tokyo's National Advanced Medical School, is diagnosed with a deadly illness called cellular sclerosis. To receive treatment, he is placed in cryogenic sleep for five years. When he wakes up, he discovers that a year after he was frozen, a global pandemic erupted-caused by the MK virus, a disease that only affects men and has wiped out nearly every male on Earth. Reito and four other men, preserved in cryosleep, survived and are now immune to the virus. As the last remaining men, they are expected to repopulate the world by fathering children with as many women as possible. But Reito remains devoted to Elisa Tachibana, his childhood friend and only love-until he learns she vanished three years ago. While the other men embrace their new role, Reito resists temptation, choosing instead to search for Elisa and uncover the truth behind the mysterious virus.
