Makoto Konno is a somewhat foolish and tomboyish high school student who spends most of her time hanging out with her two male friends. Things change one day when she suddenly gains the ability to leap through time! At first, she uses her newfound ability to do things such as preventing her sister from stealing her dessert, cheating on a test, and singing Karaoke for 10 hours. However, the small alterations she makes to the timeline turn out to have unforeseen consequences that snowball into dramatic and lethal situations for her and those around her...
Both of these shows are cute, feel-good romance stories. Also, the main characters are impulsive and determined female heroines, and I found them both to be quite charming. Although, the premise behind each is slightly different, I believe viewers who enjoy this type of romance would surely like both.
Amidst the turbulent revolution of 2025 wrought by the GGP government, Rin Ogata only dreams of becoming a ballerina; like her mother before her, Rin’s grace and agility mean she’s destined for success on the stage. However, an injury and the untimely death of her parents quickly shatter her aspirations and, for once, Rin’s existence seems purposeless. That is, until she enters the garage of a club one day and sits astride a RideBack! The RideBack, a motorcycle with arms and the ability to stand upright, offers Rin a new world of boundless movement! What she doesn’t realize, however, is that this club of RideBack enthusiasts is about to get dragged into the bloody war between the GGP and the terrorists intent on overthrowing them. Life may be more exciting now, but it’s also become very dangerous: will Rin’s natural talents as a pilot be enough in a world where racing is not just for glory, but for survival?
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.

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.
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.
Mai Taniyama is a first year high school student who lives a carefree life telling ghost stories with her friends. One day, she meets Kazuya Shibuya, the head of Shibuya Psychic Research (SPR); and together, she tags along to help him investigate paranormal activities in a haunted school building. His assistant Lin was hurt during an incident to protect Mai from danger, so what more can Mai do than to take the job as Shibuya's assistant? Along with a team of other ghost hunters, they will uncover the mystery of a strange case coming their way, while Mai starts to discover her own abilities.
Both Ghost Hunt and Library War feature a talented but inexperienced female protagonist in a somewhat comical romantic relationship with an emotionally inaccessible superior. When I saw Ghost Hunt, I immediately thought 'this relationship is just like the one in Library Wars'.
Also, in both series the comedic relationship and goofy co-workers share equal time with a serious and frequently suspenseful situation. Ghost Hunt is horror and has lulls and spikes in intensity, while Library Wars is more military/political and the drama intensity is more consistent.
