Hetalia

It's the "Meeting Of The World", and all the nations must come together to solve whatever global problems they can. However, after America starts the conference off on a bizarre note, can the gathered nations even solve the problems they have with each other? After this, it's a leap back in time to WWI...

It's WWI, and Germany, in search of the heir to the legendary Roman Empire, discovers an abandoned tomato crate sitting in the middle of the woods. However, even Germany finds himself unprepared to deal with the strange descendant of Rome.

Italy is sent back home after annoying Germany, but Germany quickly finds that ditching the cowardly nation is a task easier said than done. Especially when WWII nears and Italy takes it upon himself to declare that he's now Germany's ally.

Meet Japan. He's the newest ally to Italy and Germany, and a powerful nation in his own right. But with having been isolated from the rest of the world for over 200 years, what he sees as his "normal" behavior comes off as extraordinary to others.

An endless blue sky, pure white clouds, and a shining sea. Normally it would be just your average trip to the beach. In the case of Germany, Italy, and Japan? They've been stranded on a mysterious island in the southern sea, their S.O.S message having gone ignored as the three of them make the most of their "vacation".

Germany reflects on times spent around Austria. Meanwhile, unbeknownst to the three stranded nations, they've got company on the island and are being watched from afar, even when they're roasting marshmallows at their campfire.
