Light novels
The Familiar of Zero began as a series of light novels written by Noboru Yamaguchi and illustrated by Eiji Usatsuka under the original title Zero no Tsukaima. Media Factory published 20 volumes in Japan between June 25, 2004, and February 25, 2011. Further publication was threatened by Yamaguchi's advanced cancer,[5] which he died from on April 4, 2013, leaving the series unfinished.[6] Yamaguchi had planned the series to end with 22 volumes.[7] However, it was later decided by the publisher to continue the series in the author's absence, due in part to calls from fans to continue the series, as well as Yamaguchi's family wanting to see it completed. Yamaguchi had dictated the remaining plot of the series, including its ending, and entrusted it to the editors.[8] Media Factory released volume 21 on February 25, 2016,[9] and the final volume 22 on February 24, 2017.[10] Seven Seas Entertainment licensed the series in 2007 under the title Zero's Familiar,[11] but later cancelled the release of the novels before releasing any.
A side-story, Zero no Tsukaima Gaiden: Tabatha no Bōken, initially available as a mobile phone online serial, was released in three volumes between October 25, 2006, and March 25, 2009. It centers on the adventures of the character Tabitha, Louise's classmate. Another side story, Kaze no Kishihime, was released in two volumes on October 23, 2009, and March 25, 2010. It is a prequel about Louise's mother's youth. A companion volume, Zero no Tsukaima Memorial Book, was released on June 24, 2017. It collected various short stories and illustrations previously unpublished in book format, as well as character designs and other information, such as outlines for volumes 21 and 22 left behind by Yamaguchi. It also revealed that the last two volumes of the series were written by Yū Shimizu, author of Bladedance of Elementalers, using Yamaguchi's notes.

While Geneon Entertainment still retained the license, Funimation Entertainment assumed exclusive rights to the manufacturing, marketing, sales and distribution of select titles. The Familiar of Zero was one of several titles involved in the deal.[20] Funimation released a complete box set of the series on November 4, 2008.
