Post Apocalyptic Anime
Some of us just want to watch the world end. We just want to see it burn. But what happens afterwards? Is a new world order set up like in Shinsekai Yori? Has nature overtaken everything like in Shangri-la? Or are we looking at a setup like Shoujo Shuumatsu Ryokou where everything has come to a screeching halt because of a nuclear war?
Or maybe something like Koutetsujou no Kabaneri is something more to your liking? Whatever the reason is that you came, if you love seeing the world after it has been destroyed, then you are going to love more post-apocalyptic anime like it.
Anime has a plethora of stories which employ this formula and many exciting titles have come out of the post-apocalyptic trope.
