Hetalia theories (A Gory Demise)

The nations were not always countries, but humans, reincarnated in an alternate universe, better suited for them; a second chance at life before they go to Heaven or Hell, given better bodies with a chance of friends and family. This was not my idea, I've seen these around, but have read very few of them. They will be Creepypasta-esc, considering a character dies in each chapter.
