図書館戦争

Iku Kasahara wants more than anything to be an ally of justice--just like her prince. In the current age, the Media Betterment Act has allowed the Japanese government to impose heavy censorship on the expression of ideas, particularly those from books. When her favorite childhood book was marked for censorship, Iku felt that oppression firsthand, but she (and the book) was saved by a man from the Kanto Library Defense Force... her prince! Inspired by his example, Iku joined the Kanto library to safeguard expression of freedom, all while searching for the man she idolizes.

Set in the year 2019 in Japan. In order to crack down on free expression, a new law is passed, which allows for the government to create an armed force to find and destroy objectionable printed material. Meanwhile, to oppose this oppressive crackdown, the Library Force is created. The Library force, including instructor Atsushi Dojo and Iku Kasahara, work to protect the libraries. A fierce battle then ensues between these two groups.

Kasahara Iku and Dojo Atsushi receive an emergency recall in the middle of their date as Japan is rocked by a terror attack. Their new duty is a protection detail assigned to Touma Kurato, an author. Meanwhile, the relationship between Librarians and the Media Purity Committee is also worsening. During yet another hostile confrontation, Dojo is seriously wounded. Although Kasahara is badly flustered by this turn of events, Dojo still sees fit to entrust her with Touma's protection.

Set 18 months after movie "Library Wars." After the government's enactment of the Media Betterment Act, battles wage between the Betterment Squads and the Library Defense. The Library Defense resists censorship and advocates freedom of expression. The biggest battle awaits for the Library Defense.

Iku (Nana Eikura) joined the Library Defense Force after a member from that team retrieved an important book that was targeted for censorship. She is assigned to work under Atsushi’s (Junichi Okada) team. She endures Atsushi's harsh treatment and looks for the member who retrieved her book. She also finds herself becoming attracted to Atsushi. Iku meets female high school student Marie (Tao Tsuchiya) at the library. Maries has a hearing disability. She is also a childhood friend of Mikihisa (Kei Tanaka). Iku senses Marie’s strong feelings for Mikihisa. Asako (Chiaki Kuriyama) works as a clerk for the Library Task Force. She has frequent meetings with curator Shuji (Aoi Nakamura). This creates complicated feelings for Hikaru (Sota Fukushi). One day, Mikihisa is arrested because of a book he recommended to Marie. Official reason given is because the book is unsuitable for disabled people. The members of the Library Task Force are angered by Mikihisa's arrest.
