Hetalia - Axis Powers, Season 6

Hetalia - Axis Powers is a manga and anime series created by Hidekaz Himaruya. The story is based on world history, mainly the events of World War I through World War II. Each main character is a personification of an actual country. Each character is normally referred to as their country name, such as America or Spain, but they also have human names like Alfred or Antonio. The series started as a webcomic, and later became a web series, which is the reason for each episode being only five minutes. It was originally made in Japanese, but English subtititles and an English dub is available. So far the show has six seasons and a movie.
