Strike Witches is an Anime series about a diverse group of cute girls who are called on to use their latent magic powers to defeat an alien force. But what makes this series stand out is that it is set in an alternate reality in which WW2 was put on hold due to the appearance of the alien menace known as the Neuroi.
The aforementioned girls have magical powers that let them attach mechanical devices to their legs & allow them to carry large weapons,thus becoming like living fighter planes of that period to battle against the Neuroi.
The girls are from a rather curious mix of both Allied UK, USSR, Free France) & Axis (Germany, Japan, Italy) countries who put aside their differences & unite to fight the alien force
Despite its premise & "fanservice", this show is a delight to watch, just to see how these little ladies deal with the current threat as well as their day-to-day lives.
War is Hell, but who says it can't be cute?
