You ever want to combine Mecha anime with Magical Girls and see what happens? You should.

‘Cause what happens is apparently this show. It’s a lot of fun, and there’s absolutely no sexualization of the girls! So far! I am very depressed that I had to specify that! It’s beautifully animated, the music rocks, and the characters and plot are both very interesting. And no Fan Service™ (unless you count awesome fight scenes, which I do).
You should definitely check this out, and I will definitely be watching it again.
