<P> The story was conceived around a protagonist whose abilities cannot be measured through standardized evaluation; as such, he is mistakenly categorized as a poor performing student or an irregular . This premise served as a basis for the character, Tatsuya Shiba . Satō has two processes for scripting the story arcs: the first is to create scenarios to have characters behave and interact in certain ways; the second is to plan a scene, then script the story so it leads to that scene . Satō professed that he does not feel his characters are alive or have a will of their own when scripting them . </P> <P> Tsutomu Satō published his work on the online web novel website, Shōsetsuka ni Narō, between October 12, 2008 and March 21, 2011 . At some point during his publication on Syosetu, Satō sent an original work to Dengeki Bunko under a pseudonym . The original work's setting shared similarities to The Irregular at Magic High School causing an editor to deduce his identity and offer him a publication deal . On March 11, 2011, the author announced his work is going to be published as a light novel under the Dengeki Bunko imprint . The author expressed some regret turning free content into paid commodity and cited his financial needs as the reason . The illustrations accompanying the light novels were done by Kana Ishida . The first light novel volume was unable to accommodate the first story arc; deciding against cutting content from the web novel, it was split into two volumes and released a month later . On March 9, 2015, Yen Press announced its licensing of the light novels for English localization through Twitter . Yen Press' first volume was released in April 2016 . </P> <Table> <Tr> <Th> No . </Th> <Th> Translated title </Th> <Th_colspan="2"> Japanese </Th> <Th_colspan="2"> English </Th> </Tr> <Tr> <Th> Release </Th> <Th> ISBN </Th> <Th> Release </Th> <Th> ISBN </Th> </Tr> <Tr> <Th> </Th> <Td> Enrollment Arc (I) </Td> <Td> July 10, 2011 </Td> <Td> 978 - 4 - 04 - 870597 - 4 </Td> <Td> April 19, 2016 </Td> <Td> 978 - 0 - 316 - 34880 - 5 </Td> </Tr> <Tr> <Td_colspan="6"> <Ul> <Li> Chapter 0 </Li> <Li> Chapter 1 </Li> <Li> Chapter 2 </Li> <Li> Chapter 3 </Li> <Li> Chapter 4 </Li> <Li> Chapter 5 </Li> </Ul> </Td> </Tr> <Tr> <Td_colspan="6"> The siblings, Tatsuya and Miyuki Shiba, begin their first day at First High School, one of the nine magic high schools in Japan; the school segregates its students as first course or second course based on magic practicality .
