NPC Rescue ~Hokai Shikaketa sekai no NPC o H de kyuusai suru~ (RJ01593979)

After the overworked protagonist (you) dozes off on the last train home, you awaken to a mysterious voice—only to find yourself in another world.

According to the goddess before you, this world is now on the brink of collapse. The hero who was supposed to save it disappeared just before defeating the Demon King, heartbroken after his lover was stolen by a companion. This triggered a “bug,” causing all the men in the world to vanish.

“To restore the world, you must have children with the women of this world and engrave male DNA back into it!!”

To help restore balance, you are given a single notebook. When you open it, it contains intimate information about unfamiliar women…!

“The ability I grant you… is that all women’s affection toward you will be at its maximum from the moment you meet them. Additionally, their sensitivity, fertility, and implantation rates will all be at maximum—100%.”

Granted these outrageous, sexually focused powers by the goddess, you are thrown into confusion. But ultimately, you steel yourself, take the book in hand, and decide to dive into this other world―――
