In a world where IS Units were created by a super genius, these IS Units were Mechas designed specifically for annihilating armies and creating mass destruction but the only drawback was that it could only be manned by females! As expected this may seem cliche and a little fan service but as to be expected of a harem anime, the only male that can man the deadly machines is the male protagonist Ichika. He is soon enrolled into the elite High School that dedicated itself to training the world's future IS Pilots which is entirely all female until the male protagonist comes in, harem time!
Although the story and the plot development is terrible, mass destruction capable mechas manned by highly trained overly confident female anime girls? That sounds hot and appealing to me, although the anime itself was horrible with nothing unique or special that could be memorable, watching it wasn't bad at all, I didn't slog through it or dread watching another episode, I genuinely enjoyed it.
