The Lonely Castle in the Mirror novel
The Lonely Castle in the Mirror anime is based on the eponymous novel by Mizuki Tsujimura, who is an established name in the industry.
The novel was originally published in Japan by Poplar Publishing on May 11, 2017. Having proven to be an instant success, the novel won the grand prize in the 2017 King’s Brunch Book Prize and the 2018 Japan Booksellers’ Award.
In March 2021, Poplar Publishing re-released the novel in a two-volume paperback format.
The official English translation was published in April 2021 by Doubleday. Erewhon is set to publish a hardcover English edition on October 18, 2022.
In 2004, Tsujimura published the A School Frozen in Time novel series (冷たい校舎の時は止まる, Tsumetai Kousha no Toki wa Tomaru), which won the 2004 Mephisto Prize.
The novels inspired a manga adaptation illustrated by Naoshi Arakawa (Your Lie in April), which was serialized in Kodansha’s Monthly Shounen Magazine from December 2007 to April 2009, spanning four tankōbon volumes.
Vertical has licensed the manga series for an English release.
In 2014, the author published another successful novel — Anime Supremacy! (ハケンアニメ!, Haken Anime!), which was illustrated by CLAMP.
Anime Supremacy! was published in English by Vertical in October 2017.
