Ayato Kamina may seem like an average boy in a devastated world, but after being captured by TERRA, a military organization set on saving the world from the Mu, an alien race set on "tuning" the world, he realizes he is an instrument in deciding the fate of humanity and piloting RahXephon. Not only is Ayato the only person who can control the mecha, but he also has a terrible fate of his own. Holding onto memories of his old life and grasping to keep his own humanity, he must struggle in this new world and realize his true potential with RahXephon.
Hitomi was just a normal high school girl, until she was taken by the mysterious Van Fanel and dropped into a world of romance, magic and giant sword-wielding armor suits! Now Van, pilot of the famed armor suit Escaflowne; and Hitomi, whose hobby of predicting the future just became a frightening reality, must work together and fight the advanced technology of Zaibach: a force who want to shape Gaea to their visions of "peace". Follow Hitomi in her struggles against both these forces who seek to conquer this world, and her own confused heart.
Like RahXephon, Escaflowne is another series that deals with the fate of humanity, and a hero must try to save the world by piloting a huge medieval robot called a Guymelf. The animation is very similar to Escaflowne and the story is epic as well.
If you like Negima, You'll Like Love Hina because both have a guy surrounded by girls over the protagonist of Love Hina (Naru Narusegawa) as being Asuna
Negima is Love Hina kicked up a notch. The stories are quite different, Love Hina being about getting into college and Negima being about a 10-year old mage becoming the teacher (not magical, just regular teacher) of a bunch of middle schoolers. But the important thing with Ken Akamatsu's works are the girls, and Negima has about 10x as many. The "main" girls in each are also quite similar in temperament.
The two are almost the same with Negima being more action-packed and Love Hina being a more indepth story.
Both done by Ken Amatatsu, Both Harem mangas, Love hina is more of a comedy where Negima! is a fantasy and action manga.
In a time of great heroes, the evil Sephiroth and the power of Meteor were vanquished by a warrior named Cloud Strife and his companions.

Naota Nanbada is a boring young boy who leads a boring life in a boring town. His older brother has left for America, and the closest he comes to any excitement is when his deadbeat dad has too much sake. But things change one day when a bizarre girl zooms up to him on a scooter and smacks him in the face with her guitar. What's more, once Naoto returns home he discovers that this strange woman has arrived ahead of him and moved in! Not only does she constantly engage in perverted activities with Naota's father and flirt with the young man himself, but she also claims to be an alien who is searching for the ‘Pirate King.' Now, Naota must learn to live with this new intruder, deal with an odd government agent who sports exceptionally large eyebrows and the mysterious Medical Mechanica, and come to terms with the fact that there are a variety of robots and weapons emerging out of his head - amongst other things. Perhaps boring wasn't so bad after all...
Japan, present day: Alien Invaders are everywhere, taking over peoples' bodies. Fighting them is Isuzu Ayane, an introverted young girl with the ability to control powerful dimensional Gates. Under the guidance of Kageyama Reiji, a mysterious businessman, she battles Invaders and recruits new Gate Keepers. Will she and her new comrades be able to save the earth?
In the near future, a small team of scientists have solved the world’s energy problems with the Shizuma Device. While the development of the device was hampered by a chilling disaster, the device is now viewed as the ideal power supply; it is clean, recyclable, and can be used to power every device imaginable. However, the terrorist group Big Fire has found a way to recreate the disaster that was triggered during the item’s development, in every Shizuma Device around the world. It is up to InterPol, a group of justice specialists with extraordinary powers, to stop this nefarious plan and save the world with the help of their trump card known as Giant Robo and the young Kusama Daisaku, the crux of the robot’s power.
Giant Robo was one of the first mecha manga ever composed, and the animated version is pretty old-school, but it's still worth watching - I can guarantee you won't be bored.
GR is a bit more easy-going in the sense that it requires less thinking and presents you more awesome shounen action.
