If you liked the Saber Marionette J anime, the Anime-Planet community thinks you'd like:
Having failed to earn admission to a university, Hideki Motosuwa has moved to the big city, determined to study his hardest for next year's exams. However, an unusual distraction presents itself one unsuspecting day in the form of Chii, a robotic young girl that has been discarded in the trash. In a world where an increasing number of people turn to these 'persocoms' for company, the bonds and limits of human relationships are tested as flesh manages to fall in love with the machine itself...
In Chobits, Hidaki finds Chii who is a persocon (or a human robot). This is somewhat similar to what the marionettes are in Saber Marionette J. Of course, Chobits has some great comedy, just like SMJ.
Saber Marionette J and Chobits are both series that start out with a jovial, buoyant atmosphere scattered in with some ecchi moments, but later on shed their masks in favor of a more sci-fi, multi-layered story. They both deal with the lifelong question on the difference between humans and machines, and give out fascinating answers.
While the first is more intelligent and thought-provoking, fans of one series will undoubtedly like the other as well.
Kazuya Saotome is an electrical engineering student with a passion for computers, building his robot squid, and programming. One day he receives May, a hand sized cyberdoll, in a package from Cyberdyne Co. as a revenge tactic planted in a CD from his rival. With a little help from May to clean up his act, he may even be able to win over the heart of Kasumi, his landlord's daughter.
Hand Maid May is another anime where a guy gets surrounded by female robots and is supposed to better his life, and eventually save the people he cares for. Sound familiar? Yeah! If you liked Saber Marionette J, you'd like this one too.
For fans of Saber J, I'd definitely recommend checking out Hand Maid May. It's a little bit sillier, but then again if you like Saber J, silliness probably won't be a major problem.
Both series are about a young man and his harem of battle dolls who are madly in love with him and help him fight with several enemy.
While Machine-Doll is focused in magic/alchemy with a steampunk touch, Saber Marionette is more about mecha and technology with a futuristic approach.
Both shows feature male protagonists who go out of the way to help others and care deeply about their mechanical companions who happen to be crazy for them.
Keiichi Morisato is just your average college student until one day, fate interjects as he makes a call for take-out food. Unknown to him, he reaches the Goddess Help Line, and contacts a goddess named Belldandy, who grants him a wish. Thinking it to be a joke, Keiichi wishes for her to be his girlfriend 'forever'.
Both Saber Marionette J and Ah! My Goddess have a similar theme; and there is also a similarity in the fact that one guy gets surrounded by 3 goddesses who help him become a better person. Of course, he isn't saving the world, but at least he has 3 females. Still yet, if you enjoyed one of these series, you'd probably like the other.
Murao Mima has created a robot daughter named Key, but after raising her for a very short time, Mima dies, leaving behind cryptic messages telling Key how she can become human. Key must struggle alone to learn the harsh lessons of life and search for the 'key' to her own dream: the power of 30,000 friends to make her a real human girl.
