Libra of Nil Admirari is directed by Masahiro Takata and features animation by Zero-G.
A secretive organization known as the Imperial Library Intelligence Asset Management Bureau (also known as “Fukurou”, or “Owl”) exists to protect these books.
The story of Libra of Nil Admirari is set in an alternative timeline in which the Taishou Period didn’t end in 1926, but instead continued on for an additional 25 years.
