Books like Hetalia: Axis Powers, Vol. 1

It's a cute manga that's set in World War 2 through present day that actually manages to amuse and both educate at the same time. The manga is about anthropomorphic personifications of some of the countries during World War 2, with adorable comic strips about certain events. The personifications of the countries somewhat poke fun at national stereotypes, such as America being loud, brash yet good natured and friendly, or Japan being the quiet but secretly-an-otaku, etc, without being super offensive. A great read if you want to both laugh all while learning about WW2. :]<3
