Infinite Stratos is a Light Novel series written by Izuru Yumizuru, with illustrations provided by Okiura. The first volume was published by Media Factory under their MF Bunko J label on May 31, 2009.
Due to conflict between the MF publisher and the author, publication of the light novels was under suspension. Later, the author confirmed that he is simultaneously writing a new work while continuing the series through Kodansha. Now the publishing of the novels were moved to Overlap under their Overlap Bunko imprint, with CHOCO replacing Okiura as the illustrator. Reprints of the first seven volumes begun on April 25, 2013, starting with the first two volumes.
The light novels are being translated into traditional Chinese and the first volume was published and released by Sharp Point Press on November 9, 2010. The Chinese translations of the light novels were originally under indefinite suspension due to Yumizuru citing that Media Factory's overseas representatives were engaging in contracts with foreign publishers without the author's permission. Yumizuru had also stated that he was willing to fight over this matter in court if necessary.
On February 27, 2018, J-Novel Club announced it had licensed and begun translating the series into English.
