World's End Harem, Vol. 1

The Man-Killer Virus--a lethal disease that has eradicated 99.9% of the world’s male population. Mizuhara Reito has been in cryogenic sleep for the past five years, and now awakens to an all-female world where he himself is the planet’s most precious resource. Reito is given one simple mission: repopulate the world by impregnating as many women as possible--whether he wants to or not!
