Hetalia - Axis Powers

Based on a popular web-released manga series by Hidekazu Himaruya, this has been described as a "cynical gag" story set in Europe in the years between WW1 and WW2 (1915-1939), using exaggerated caricatures of the different nationalities as portrayed by a gaggle of bishōnen boys. For example, the Italia Veneziano character is into pasta and women.
Italy, once home of the strongest empire in the world, has changed. This is the story of Italy, now a cowardly pasta-loving fool, and his friends (other personified countries of the world) as they live through strange moments in world history.
