Hello,
And here we are for the last post of the week end...this time we'll analyze a new Light Novel / Manga / Anime that is currently on air in Japan. Its name is Infinite Stratos and is currently slated for a 12 episodes run. (still only 4 episodes are broadcasted)
First of all let's go see the synopsys :
In the near future, a Japanese scientist engineers a powered exoskeleton called "Infinite Stratos" (IS). Possessing technology and combat capabilities far more advanced than any other weapon system, the IS threatens to destabilize the world. Faced with such an overpowering weapon, the nations of the world enact the "Alaska Treaty", which states that IS will never be used for military combat and that existing IS technology must be equally distributed to all nations, to prevent any one nation for dominating the others. The introduction of the IS does however have a major effect on society. As IS can only be operated by women, the power balance between men and women is broken, with women coming to dominate society over men.
Ten years after the first IS were introduced, the world has entered a new age of peace. The peace is shattered, however, by an unexpected discovery. A 15 year old Japanese boy, named Ichika Orimura, is discovered to be capable of operating an IS. Realizing the potential, Ichika is forced by the Japanese government to attend the prestigious Infinite Stratos Academy, an international academy where IS pilots from all over the world are trained. Thus his busy school life surrounded by girls begins.
Quite a generic plot for a generic harem anime series. From the few episodes I've watched the story presented itself like the classic "ingenue protagonist followed by hundreds of girls, but does not notice" category, and while the story by itself isn't the best, the quality of animation in the battles and for the characters makes up the rest to make this a decent series to follow.
Of the characters till now presented I'm liking a lot Huang Lingyin, but I'm waiting to give my vote at the end of the whole series. (Houki Shinonono is the runner-up and may catch up in my heart 
)
I'm most likely buying the first volume of the manga in this february shipment, and I'll make a new post when I'll get it to describe what is different between anime and manga.
If you're are into the harem series, give it a shot and watch the anime. You may end up liking it like me. 
That's all for now,
