The dead become stone books that share their memories with anyone who reads them, and the Bantorra Library that keeps those books is at war with the Shindeki Church. Hamyuts Meseta, the battle-hungry acting director of the Library, commands the Armed Librarians, trainee Noloty Malche among them, against a cult willing to sacrifice brainwashed followers for its cause. This ten-volume light novel series is the original work; the manga Tatakau Shisho to Koisuru Bakudan adapts its first book.
