Following a string of heartbreaks, Ikuto Watarai decides to go into the mountains to clear his head and dump women for good. He laments his previous experiences until a massive storm forces him to take cover in a cave. With nowhere else to go, he explores deeper into the unknown and gets hopelessly lost. The world goes dark and he accepts his fate...

But instead of waking up in the afterlife, he finds himself in a small, aging village that the world has all but forgotten. Looking around, he see that his saviors are three girls? And they are calling him their destined "messenger" who is to revitalize their home by giving birth to a new generation?! Now that Ikuto's has arrived, he can't leave until he completes his duty!

There's just one catch – these girls have a secret under their skirts...
