Every girl introduced is going to be the MC’s new wife eventually. He’s already the village meat dildo. The author failed to do anything with the kid aside from having it exist as a symbol of proof he smashed a girl unprotected. All that’ll happen now is his harem will grow cancerously large. They’ll just introduce different types of exotic monster girl or demihuman for the MC and reader’s dick as the village grows stronger on all scales military might, political prowess, and agricultural exports, while the demon king country and army continues to appear more and more pathetic in comparison. Humor me if I’m wrong though. I’d sure like to be surprised.
