Description: (from volume 1 of the manga) Iku Kasahara has dreamed of joining the Library Forces ever since one of its soldiers stepped in to protect her favorite book from being confiscated in a bookstore when she was younger. But now that she's finally a recruit, she's finding her dream job to be a bit of a nightmare. Especially since her hard-hearted drill instructor seems to have it in for her!
Edited: (found a better series description) In an alternate Japan, the Media Improvement Act was passed that allows the government to censor all material it considers dangerous. This pits them against the state-run library system, which has the legal right to protect the freedom of expression and allow people to read all literature. When the conflict becomes violent, the Library forms a Library Defense Force to oppose the censorship and be able to fight the Media Betterment Committee. Iku, despite the opposition from her parents, enters the Library Defense Force in search of the man who had saved a book for her when she was in high school.
Reason why I'm suggesting this: I absolutely loved the manga series and would really like to read an official English licensed translation, including translations of the two side story volumes.
I’ve never read the manga or seen the media but I love the premise so I’m down
