Ichika Orimura is a normal teenage boy who just enrolled in high school, which happens to be the famed IS Academy, an all-female educational institute to teach the students to operate the multi-purpose exoskeletons called Infinite Stratos. In adverse of what normal boys would find paradise, Ichika finds himself very discomforted being the center of attention in a girls-only class and to the world for being the first male to activate an IS which can only be operated by females!

Ichika tries to get through the first day with his sister, Chifuyu Orimura as his homeroom teacher. He goes through a rough reunion with his childhood friend, Houki Shinonono, who becomes his current roommate. The following day when his class votes him to be their class representative, the British cadet representative, Cecilia Alcott is against it and challenges him to an IS duel.
