Infinite Stratos also written as IS is a Japanese light novel series. In the near future, a Japanese scientist creates a high-tech powered exoskeleton called "Infinite Stratos" (IS). Possessing technology and combat capabilities far surpassing that of any other arms system, the IS threatens to destabilize the world. Faced with such an overpowered weapon, the world's nations enact the "Alaska Treaty", stating that ISes shall never be used for military combat purposes, and that the existing IS technology must be equally distributed to all nations, to prevent any one nation from dominating the others. However, sometime after the IS was introduced, society has undergone a drastic change. As ISes can only be operated by women, there is a shift in the power balance between men and women, where women now dominate society over men.
