Hetalia: The World Twinkle
The sixth season of Hetalia.
In a world where nations are personified as humans, Italy has joined Germany and Japan as a member of the Axis Powers. However, he proves to be cowardly, carefree, and lazy--very different from his strong ancient ancestor Rome. Meanwhile, the Allies must deal with their own personal quirks.
Hetalia explores the alliances, rivalries, and relationships between nations. Countries are depicted as a mix of truth and stereotype--America loves heroes and fast food, Germany is stern and strict, and France is a romantic. Though its main story line follows WWII, it includes character interactions from throughout history. This is a comedic look at their past and progress.
