I think if I had one very minor gripe, it's that 1786 months isn't even 150 years, so people forgetting about the war and the seal doesn't make a whole lot of sense.
Wow, those spreaded images on page 11 and the last one. Simply wonderful.
@kagypoo While I understand what you mean, how much do people really know about the stuff that happened 150 years? I don`t think it is about forgetting, but rather the theme of this manga is information itself (as shown with the fake news part in this chapter). How is information getting distorted over 150 years.
