Symphogear is the kind of experience that you'd get if you were watching Futari Wa PreCure and King of Braves GaoGaiGar at the same time while listening to Nana Mizuki music in one ear and Fripside in the other. In short, it's AWESOME. But those that are expecting it to make sense will be badly disappointed. Gonna say this up front: The plot is stupid. It's /unbelievably/ stupid. This however doesn't matter because it's carried by loveable characters and awesome action scenes. Every episode has at least one fight scene, always with fight music, and the action is completely over the top. Bottom line: This is a show you willeither love or hate. There is no in between.
Also it's VERY GAY. There is only one heterosexual woman in this show, and she doesn't show up until season four.
