Cover of issue 1
WWII-era tanks are used in a sports-like event that pits girl high schools against each other in non-lethal combat. This crazy ass premise has spawned a ton of successful manga, animated movies, books, video games and a bunch of other shit. Personally I think its pretty silly and weird but that's the Japanese for ya. Read the manga here and watch the anime on Netflix.
Stupid ass stuff but it kinda like Weird WWII, right?
