Yessss, vindication!
I commented earlier exactly on this scenario, but Sara and the author not only did it but in a smarter way than I thought.
I thought that the next course of action for Sara was to align with a foreign country because what man in power wouldn't love an endless supply of babes superior to humans in every way?
But building a solid base solely in a remote village is even better. Doing it at a national level from the get-go would put a target on that country's back immediately, they would and should get nuked immediately.
I think we might have a timeskip or see Sara next when she built up her empire within Japan overnight, with plenty of lewd and mighty sights. It would give her time to encourage her daughters to be as smart and capable as her, making their side even more daunting to take on.
They're nation-building... while Ichi is on the run (but back in his last known residence like an idiot?), broke, and giving brojob to incels.
Yeah, I'm putting all my stocks on Sara's Empire. Bow ya shits, bow to the Sphere Queen 🙌
