If you liked the Saber Marionette J anime, the Anime-Planet community thinks you'd like:
Keitaro Urashima is somewhat of a failure. In order to fulfill a promise he made to a girl fifteen years ago, he has tried time and again to get into Tokyo U but has never managed to pass the exam. However, fate smiles upon him and he ends up working for his aunt, managing an all-girls dorm! Living with the feral Kaolla, the timid Shinobu, the sake-loving Mitsune, the blade mistress Motoko and the punch-happy Naru, can Keitaro keep his focus and keep his promise? And will he ever end up meeting that girl from his past?
I'm not sure exactly what about Saber Marionette J reminds me of Love Hina; maybe it is the fact that they are both, on some levels, coming of age stories about a regular guy, maybe it is the fact that the main female characters drive the story (not to mention male characters into the air with their fists). They both end up being romantic comedys with a similar feel. I am pretty sure that if you enjoyed one, you will enjoy the other.
Shichiri Tasuke is an average teenager, who lives on his own while his archeologist father roams the globe searching for ancient artifacts. One day, Tasuke receives a package that contains one of these artifacts, and from it appears Shaorin: a guardian spirit charged with protecting the person who brings her forth. Shortly thereafter, a second artifact arrives which contains another spirit, Ruuan, whose job is to bring her master happiness. Unfortunately, Ruuan and Shaorin are old rivals and they cause no end of trouble while vying for Tasuke's attention.
Saber Marionette J and Mamotte Shugogetten! are two series that share many elements in characters and plot. Certainly the series have their differences; the former features humanoid-like battle-ready “marionettes” while the latter features spirit-like “shugogettens” from ancient artifacts. But when transposed onto each other's settings, the two series share a similar plotline carried out by characters that resemble one another -- compare Cherry from SMJ to Shaorin from MS, for example. The male protagonists for the two series, Otaru for the former and Tasuke for the latter, are both ordinary boys who used to live alone until they awaken the marionettes or the shugogettens. Both marionettes and shugogettens awaken from a long sleep, attach to and live with the male protagonists, and devote themselves to protect them by the series' end. While Saber Marionette J does have a more in-depth, involving plotline on a greater stage relative to episodic and comic-oriented Mamotte Shugogetten!, both series explore common themes such as human nature, sacrifice, and desire. The humor of both series is drawn from the behaviors of rather tactless and naïve marionettes and shugogettens along with the intrusions of some unusual supporting characters. If you have enjoyed the characters and the overarching plotline of one of these series, you might wish to check out the other.
In the mystical world of Shangri-la, demons and humans live side by side, watched over by a parthenon of ancient Chinese gods. But when normally-civilized demons start to go berserk, the gods require the services of Genjou Sanzo - a Buddhist priest with a magical gun, an evil-banishing scripture and a take-no-prisoners attitude. Aided by the ancient monkey god Son Goku, the half-demon Sha Gojyo and the demon exterminator Cho Hakkai, he sets off on a treacherous journey westward, with armies of demons, dark mages and angry gods all standing in his way...
Twelve years ago, an incident known as "Blast Fall" unleashed major destruction and chaos. Now, years have passed, and mankind has learned to adapt by incorporating cybernetic limbs into its citizens. Roy Revent is a bounty hunter known for his violent acts towards criminals due to the loss of his daughter in Blast Fall; and when a criminal tries to take revenge on Roy, an unknown girl falls from the sky and saves him. She has no memory of who she is, or where she came from. With the help of Miranda, his boss and landlord, he takes in the girl and gives her a name of Solty. What is the real identity of Solty, and what caused Blast Fall?
If you're interested in "When the people of Earth leave and search for other planets to live on." and "Mechanical Dolls and Arms" then Solty Rei and Saber Marionette J arent far from each other, as all the characters try to survive the planet's conditions and a human made computer over protecting human civilization.
It was just a juvenile search for adventure that brought young mystic Nakahito face to face with the android mega-weapon, Kurumi. With just a kiss, she is activated and answers only to him. Now they embark on a comedic journey that will carry them across Japan to discover the secrets of the Steel Angels and how such technology has come to exist before the advent of television. In their travels they will encounter spies, army agents and rogue Steel Angels but the real discoveries lie in the heart of a young teen and the miracle he has awakened with a kiss.
mostly just a gut feeling the 2 animes have notable simularities in their stories. In both animes the main charicters have three not so normal women fall on them. In both animes 2 of the women are trying to get him to fall in love.
Both Ageha and Ganta have their world flipped upside down oneday due to a fateful encounter.

Similarly in Psyren Ageha comes across a mysterious calling card which is revealed to be gateway to another world, which brims with superpowers and monsters. Its a do or die world where Ageha must train and attain comrades to come out unscathed and continue his normal life,
Both series have great action and good amount of bloodshed.
