In the near future, the federal government creates a committee to rid society of books it deems unsuitable. The libraries vow to protect their collections, and with the help of local governments, form a military group to defend themselves---the Library Forces! When the director of the Kanto Library Base gets sick, a temporary replacement is assigned, according to regulations. But Iku and her roommate Asako discover a trail of missing books that lead back to the temporary Director. Has he betrayed everything the Library Forces stands for and handed books over to the enemy?!
