The Irregular at Magic High School, known in Japanese as Mahōka Kōkō no Rettōsei (魔法科高校の劣等生, lit. "The Poor Performing Student of a Magic High School"), is a Japanese web novel series by Tsutomu Satō. It was published on Shōsetsuka ni Narō, an internet web novel website, between October 2008 and March 2011. Satō reached a deal with Dengeki Bunko and began releasing his work in a light novel format beginning July 2011. In 2013, each story arc received a manga adaptation with varying manga artists and publishers. That same year, an anime adaptation by Madhouse was announced and was broadcast between April and September 2014. The Irregular at Magic High School franchise had been localized for English by two companies: The light novels and one of the manga adaptations are licensed by Yen Press while Aniplex of America licensed the anime series. The anime series was simulcasted on four networks, and was later made available on Netflix.
Magic is a product of neither legends nor fairy tales, but instead has become a technology of reality since a time unknown to people. Supernatural power became a technology systematized through magic, while magic became a technical skill. A "Supernatural Power User" became a "Magic Technician." Magic Technicians (in short, Magicians) are nurtured through Magic High Schools and Universities.
