Wait, so how is Nitta involved in this? Also, not "Prime Minister" but "President"? Hitomi already cleaned house and reform the government in the same year she is given office? P.S. I just remembered that Hitomi has a fake id; so instead of in 15 years, everything could be happening in the next chapter.
suddenly you realize that hitomi is the real protagonist in this, the story of her rise and conquering of the world. calling it "hina matsuri" is an effective diversion.
