Ichika Orimura is the first male IS pilot, and is forced to attend an all-girls' school where he runs into rivals, childhood friends and corporate spies.
Girls from all over the world gather at IS Academy to learn how to become IS pilots. However, since the protagonist, Orimura Ichika, can somehow pilot the IS even though he is male, he was forced to attend IS Academy as well. As the only male in this school attended by girls of all shapes and sizes from around the world, including his childhood friend and kendo buddy, Houki, tempestuous action battles and romantic encounters await him.—Apple TV
In the near future, an eccentric Japanese scientist engineered a powered exoskeleton called the Infinite Stratos (abbreviation: IS). Possessing technology and combat capabilities far more advanced than any other weapon system, the IS threatened 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 from dominating the others. The introduction of the IS, however, caused a major effect on society. As IS 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.
Ten years after the IS was initially introduced, the world has entered a new age of peace. The peace is shattered, however, by Ichika Orimura, a 15-year-old Japanese boy who is inexplicably able to operate an IS. Realizing the potential, the Japanese government forces the bewildered young man to attend the prestigious IS Academy, an international academy where IS pilots from all over the world are trained. Thus, Ichika's busy high school life surrounded by nothing but girls and IS battles begins.
