Inside a certain day's dream, [The Goddess of Love and Beauty, Yutaka Minoru] forcibly woke me and gave me a servant and a strange power. And then, I was told about the [Goddess's Request].

According to the Goddess, "Right now, the male s*x chromosome is on the decline. The male population itself is falling, and at this rate, no more men can be born. But you are different. In millions of people, you alone have two male chromosomes. You have the super rare XYY gene! So that humans can once again reproduce normally after sex, to preserve the integrity of natural childbirth, go spread your DNA!!" "In other words…" "Your quota is to screw at least 100 girls!

If you manage to succeed, I'll reward you! If you fail, I'll send you to hell!" And with that, I was given a strange power from the Goddess, granted a servant, and forced to attempt to screw 100 girls. "You have until you graduate from high school." No wait, that'll be impossible! "I'm not popular at all, and I'm a virgin who has never even had sex! There's no hope for me to do adult things!"
