The novel was originally released from KADOKAWA in two-volume hardcover edition in September 2014, then re-released as four-volume bunko edition in June-July 2017.
Toho announced today that the release date for the anime feature film adaptation of Nahoko Uehashi (Moribito series, The Beast Player)’s fantasy novel series Shika no Ō / The Deer King is postponed to sometime in 2021 due to various reasons.
The film was originally set for a release on September 18, 2020, but no trailers had been posted even just one month before its release.
