Story
Think of it like WWII, except every country is a pretty boy instead. A hilariously stereotypical pretty boy. America loves burgers, Russia is into the vodka, and China has pandas and a wok. It is centered mostly around Italy, who has both a North and South character. The Hetaria portion of the name is probably mocking Italy, as Hetare means "Useless."
