If you liked the Toshokan Sensou anime, the Anime-Planet community thinks you'd like:
Henrietta is a young girl who works for a "welfare group" that does the government's dirty work. Cybernetically-enhanced and specially-trained, she is one of a group of elite hit-girls, remorseless killers with no memories of their past. Jose, her partner, has taken care of her since she was brought into the organization following the murder of her family, and struggles between his affection for her, and his opposing duty to his employer. But, time is running out.. for with each bullet they fire, Henrietta and the other girls lose a little more of their humanity.
Both of these anime share a similar overall feeling, although Library War is far more "silly" in it's approach. They have gun-combat action scenes and especially the sniper segments reminded me of each other. Both deal with government and politics, although in different ways. While these two are still very different from each other, I believe someone who liked Library Wars would proabably like Gunslinger Girl, especially if you wanted something similar but with a more mature and serious tone.
28-year-old Hiroko Matsukata is the definition of a workaholic. On top of smoking too much, rarely having sex and having lousy luck nurturing her romantic life, she works excessively to get the job done. Alongside many co-workers at the weekly news magazine Jidai, Hiroko tirelessly works on countless stories – thus negating any chance of a social life. Can Hiroko balance her home and work life, or is she doomed to be a 'working man' forever?
Book worms will definitely appreciate the literary focuses of Library Wars and Hataraki Man. Besides that they both work with literature, these two titles have very interesting, adult characters who deal with subjects like hard work, career, life philosophy and relationships, and politcs. Both are great josei/seinen titles.
Sion is intelligent, highly educated and lives a privileged life within the walls of No. 6, one of six city-states that was built after the world was destroyed from war. But Sion's comfortable existence changes forever when he meets Nezumi, an escaped convict, on the eve of his twelfth birthday. Due to his assistance in keeping Nezumi safe, Sion loses his rights and is forced to live in the lower town, where he becomes a normal citizen. Four years later, Sion finds himself back in Nezumi's company and in the midst of a dangerous conspiracy that leaves a trail of bodies in its wake. What is really going on in No. 6?
Both are excellently produced, intelligent dystopian stories with great chemistry (in my humble opinion) between the two main protagonists. Library War is obviously more militaristic, while No. 6 is more just creepy/strange in certain respects (you'll see). Also, if you care, one difference is that Library War's pair is male-female with a more categorically romantic relationship, while No. 6's lead pair is two guys with a MUCH more ambiguous friendship/relationship. Long and short, I loved Library War, and I'm loving No. 6.
At the turn of the twenty-first century, policing in Tokyo has taken a very unique approach: officers fight crime with cutting-edge mecha called Patlabors. Division 2 of the Tokyo Metropolitan Police Special Vehicle Section 2 is one team entrusted with these powerful weapons, but its assembly of clumsy eccentrics could prove a challenge all of its own. Under the staunchly old-fashioned leadership of Chief Sakaki, there are, among others, deadpan Captain Goto, mecha-obsessed Noa Izumi, and straight-talking Asuma Shinohara. Follow them as they try to outwit mad terrorists one minute and survive dysfunctional team dynamics the next!
Both are slightly futuristic (Patlabor more so), and focuses about new and special branches of government: library military forces and police mecha task forces. There is lots of focus on characters, a good amount of humour and are very down to earth.
If you liked either one you should do yourself a favour and check the other one out.
"Labors" are large construction robots that are now being used to commit crimes. To meet the challenge, Special Vehicle (SV) units are established by the Tokyo PD. However, the Second SV unit is a total joke. Determined to change this, Izumi and Shinohara become pilots of the new Ingram 98 police labors, and are determined to change that reputation, with the help of the SV-2 gang of misfits.
In many ways, Patlabor and Library Wars are built up around the same story: a young female joins a quasi-military unit filled with dedicated but quirky characters. The story focusses on her acceptance into the corps and her achievements, while at the same time telling a larger, if somewhat episodic, story. If you like one, you will likely enjoy the other.
