I'm astounded by Hajime Isayama. He's managed to cause shockwaves to millions of fans, evoking philosophical discussion over the ethics of procreation, the lengths one would go to achieve freedom for their people, a dilemma regarding whether a race with an extreme potential for danger, but also good, should be allowed to exist in the world.
He's undoubtedly witnessed the growing pessimism and nihilism, declining birthrates, manipulative identity politics, and race guilt in 1st world countries and has sought to confront it. I applaud him for it. SnK was perceived to be nothing more than a giant zombie story by millions, but look at it now. SnK may very well ascend to being a philosophical treatise against pessimism. This could be a tale that changes the very course of history.
Neon Genesis Evangelion only deals with the psychology of the individual (depression, suicide, trouble socializing, offspring-parent relationship) While it has its importance in the anime industry and undoubtedly enriched the lives of millions, I believe SnK has more potential to restore the spirit of Japan.
SnK deals with the psychology of groups and the nation (antinatalism vs natalism, race guilt, propaganda, historical revisionism, healthy vs dangerous nationalism )
I have faith in your ability to reverse the declining birthrates of Japan and to set it back on the course of growth, Isayama, you Advancing Giant of an influencer. Keep dedicating your heart. After all, you started this worldwide popular story didn't you? It's name... is ShingeKI NO Kyojin.
