During an accidental run-in with a hibernating IS suit, it is revealed that he possesses the innate ability to operate an IS-the only male in the world capable of doing so. However, a 15-year-old Japanese boy named Ichika Orimura changes everything. Ten years after the IS was initially introduced, the world has entered a new age of peace. 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. However, sometime after the IS was introduced, society has undergone a drastic change. 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. Possessing technology and combat capabilities far surpassing that of any other arms system, the IS threatens to destabilize the world. In the near future, a Japanese scientist creates a high-tech powered exoskeleton called 'Infinite Stratos' (IS). A second series aired from October to December 2013.
