In the not so distant future, society in japan has rapidly embraced harems to counter declining birthrates. The prevalence of the "harem end" rose to such absurd levels that 4 out of every 5 males never form a healthy long lasting relationship with women and 9 out every 10 women engage in polygamy. In this society harems are now treated as small business entities in themselves with all the new tax breaks and subsidies that each new harem member brings resulting in NTR on a scale never seen before.
One man reviles this shift in society as the one woman he's in love with is constantly under threat of being swallowed up by one of these harems. It is only through his valiant borderline criminal efforts that he's been able to protect their budding relationship from being nipped before it ever gets the chance to blossom. This same man however, has only himself to blame for his situation as he was the cause of all this.
One day after watching his favorite girl in an anime series lose to the main heroine in love, the frustrated young teenager cursed copout endings and wished that harem routes would be the true end. Unfortunately for him, the gods had listened and they granted him his wish by pushing the young man's best friend into pursuing such an end for his girls leading to a public confession that went viral popularized the harem end movement.
Now years later, he finds himself visited by one of those gods who herself detests the situation and wants it reverted. To do so, he must partner up with the foxgirl and break his bestie's harem to undo the magic binding the men and women of their nation. Hijinxes and moral quandries are abound as the two become closer to each other and the man must come to a decision on what it means to live his life correctly.
