Mary Sue and Edgelord try to make post-WWI Germany into a better place by teaming up with 2 teenagers and a Chuck-Norris lookalike. It goes about as well as you'd expect until Princess Mononoke joins up with her for some reason, and then the goddamn Bat Man decides he's going to help. They liberate post-WWI Germany, but the new leader is a fake Hitler before he was Hitler who is in deep shit after the war since some asshole from Chinamerica says he'll start WWII if fake Hitler doesn't do what he says.
WWII happens anyway because people are racist bastards and a nihilistic 1,000-year old bishounen wants the world to end. He pulls some strings, a bitch wakes up and nukes the world with a stone bomb, and all the good guys have to climb the Empire State Building to smack a bitch. They then have to cast Polymerization on the bitch and a little girl to turn the bitch into her original non-bitchy self, and the world miraculously becomes un-stone-nuked. Happy end.
