Infinite Stratos Plot Summary: Infinite Stratos (IS), a weaponized exoskeleton system, has become the dominant tool of warfare and conflict. Unfortunately for the men in society, only women are able to operate Infinite Stratos…with very few exceptions. One of those exceptions is Ichika Orimura, an orphan raised by his older sister, who is herself a famous IS pilot. When his compatibility with Infinite Stratos is discovered after he accidentally touches one at the age of 15, he is given a scholarship and enrolled in a school that specializes in training IS pilots. Which means an interesting life surrounded by girls for this shy, unassuming boy.
