Guys, I have something to tell u.
That's exactly what Kishi want u to feel!
Kishi as always put a lot of hidden image and meaning in this manga(with a lot of Japanese religious stuff).
I have no doubt in writing this statement: Kishi is giving u a history class.
Why? My father went to japan once last year, and what he told me is that every single person there is devoted to his country, and it's prosperity. Why again? Because of the war and THE BOMB! The war and the fact that they were the only country in the world to ever experience a nuclear strike, made every single Japanese brother and sister. They all have the same goal, the prosperity of their country.
So knowing that this bomb mark their spirit for generation to come, don't u see some resemblance in the manga and the actual facts?
The gigantic shinra tensei look a lot like an atomic bomb to me...Kishi is making us see the American trough his own eyes (no offense to any American). We hate pain as much as the Japanese hates the American for destroying their land and killing their people in ONE SINGLE BLOW.
This manga as turn into the representation of a scared population and their arch enemy (economically and ideologically).
