Zettai Junshu☆Kyousei Kozukuri Kyokashou!!

Humanity is undergoing a dire crisis: women densely populate a world in which almost no human male can be found, the ratio being one man for every 10,721 women. To solve this grim predicament, governments issue licenses to men, encouraging each to copulate with girls of their choice in hopes of restoring the balance between sexes.

As the only male in his city, Takumi Ibuki receives his license and goes about his duty. In an environment where there are females as far as the eye can see, whether it be with his school's ace, with his childhood friend, or even with his sister, Takumi will do his best to save humanity from its impending extinction!
