I will withhold my judgment for now.
The first episode seemed solid enough, but not particularly inspiring.
Kinda Strike Witches with mechs instead of airplanes, with Armored Core-style Arena sport instead of war (yet) and male hero.
Speaking of Strike Witches, the redhead from cafeteria = Minna. Only voice actor is different.
I do wonder how they will take up (if at all) the fact he's the only male capable of operating the IS.
Wherever it's the sheer luck-of-the-draw natural skill, or something...hmmm....more sinister. He did mention he has a problem recalling a certain period of his life so...
