In a time and place where one’s soul can be morphed into a weapon, there are modern-day magicians called Mage-Knights. Although Kurogane Ikki is a student at an institution that trains Mage-Knights, he has no particular talent in magic and is labeled the "Failure Knight" or "Worst One." Getting way less than average marks in the scorings, he was forced to repeat a year. But with the arrival of a new head of the institution, a new rule was created: knights whose abilities are compatible, as decided by the board, must share rooms and attend practice and training together throughout their school years to bring up their abilities to the max. It is a rule to implement the absolute verdict of ability. Ikki’s roommate, Stella Vermillion, turns out to be a princess of another foreign country. Stella is a Rank A knight: the type of genius in magic who only appears once a decade. When Ikki walked in on her while she was changing her clothes, it caused a huge misunderstanding (since neither yet knew of the new rule) which eventually ended up in a duel between the two of them. The punishment (or as some might see it, the prize) of the losing side is Eternal Submission to the winning side. Forced to live the same room and practice magic together throughout all their school years, how will Stella and Ikki’s relationship evolve?
In the near future, a Japanese scientist engineers a powered exoskeleton called "Infinite Stratos" (IS). Possessing technology and combat capabilities far more advanced than any other weapon system, the IS threatens 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 for dominating the others. The introduction of the IS does however have a major effect on society. As IS can only be operated by women, the power balance between men and women is broken, with women coming to dominate society over men. Ten years after the first IS were introduced, the world has entered a new age of peace. The peace is shattered, however, by an unexpected discovery. A 15 year old Japanese boy, named Ichika Orimura, is discovered to be capable of operating an IS. Realizing the potential, Ichika is forced by the Japanese government to attend the prestigious Infinite Stratos Academy, an international academy where IS pilots from all over the world are trained. Thus his busy school life surrounded by girls begins.
