Distributor Anime Limited have been fairly quiet surrounding the release for Riddle Story of Devil (Akuma no Riddle). Years have gone by and still no news for the title aside from pre-order listings appearing and delisting.
Today we have discovered via social media that Riddle Story of Devil will no longer be released for the UK & Ireland on Blu-ray & DVD. The reason is due to the rights no longer under their name.
Unfortunately that it correct, we no longer hold the rights to release this series on home video, so listings for this title have been removed from retailers. ^AH
