Axis Powers Hetalia (ヘタリア) is a historical comedy manga and anime series by Himaruya Hidekazu, consisting of vignettes (mainly in a World War II-era setting) acted out by anthropomorphic characters representing the nations of the world. Most nations actually have full human names, but those aren't used on Danbooru, not even as aliases.
