If you liked the Rizelmine anime, the Anime-Planet community thinks you'd like:
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.
I reccomend this anime because in both of the animes there is a guy who falls in love with an artificially created girl which is lives with him, This is the main reason buth the 2 animes are similar because of more than this. First of all in both of them the girl is created by a verry powerful organization which has some agents living with the main characters (in Rizelmine, Papa A,B,C and in Hand Maid May, the other female robots) besides all of the agents try to encourage the relationship between the main characters. On top of all this there is also a similarity in the "Bad guys". The main male "evil character" in both of them is rich and spoiled and the female "evil" character is connected with the organization which created the main character, and both of the "evil" characters work together because they like one of the main characters, Ther eis one more similarity between the "bad" guys but it will be too much of a spoiler if i say it :P.
Kotoko Aihara has always been in love with Naoki Irie; he’s tall, handsome, and rumored to be the most intelligent student in Japan – who wouldn’t be? Only one thing stands in the way of a relationship with Irie: Kotoko is ditzy and is at the bottom set of her school, and Irie-kun hates nothing more than ditzy, stupid girls. When disaster strikes and Kotoko is forced to move in with Irie-kun’s family, she suddenly sees her chance to bridge the gap. After all, even cool, super-intelligent guys must have a soft spot, right?
Ten years ago, Senpeita Kobayashi fell in love with the girl of his dreams; she left his life, but promised that in ten years she’d see him again and become his bride. Fast forward to the present, and Senpeita is a typical student attending Akebono Academy. That is, until the wide-eyed tiny robot Kemeko crash lands in his bedroom and proclaims herself to be Senpeita’s new bride! As if things aren’t strange enough, Senpeita soon discovers that inside Kemeko is a beautiful girl – a girl who has an uncanny resemblance to his lost love! All Senpeita wants is to be a normal boy, but now he must keep himself out of the way of flying fists, raging jealousies, and battles between Kemeko and Mishina – a global corporation that has a vested and dangerous interest in Senpeita!
Aoki Daisuke is a fresh, new elementary school teacher, eager to help shape and guide his young students. But he got more than he bargained for with Kokonoe Rin! This saucy third grader has knowledge beyond her years, and a deep-seated mistrust and loathing of adults. She will go to any lengths to protect her friends Kuro and Mimi, including harassment, extortion, threats, and sexual blackmail. And yet, with her friends, she is kind, caring, and self-sacrificing. Can Daisuke gain Rin's trust and save her from her dark side without falling victim to it himself?
Both of these anime involve a little girl that is in love with a boy/man that is older than themself. I watched Kodomo no Jikan way before I had ever watched Rizelmine, but watching Rizel I kept thinking of KnJ. I also enjoyed both a lot, so if you enjoy one of these series, chances are you'll like the other just as much.
Fifth grade is a time for learning and growing and... getting into a whole mess of trouble! Class 5-2 is a "typical" fifth-grade class whose members always seem to be up to something. The leaders of their group are Ryota and Chika - Ryota's childhood friend who has a crush on him that she can’t seem to confess. While Chika continues on, remaining a close and valued friend, Ryota continues to be a typical boy who is oblivious to her feelings. Furthermore, he can’t seem to stay out of trouble with the ladies! Different situations keep their lives busy during school – everything from loose teeth to getting locked in the PE storage room. School is much more enjoyable when you are young and full of dreams!
Perverted humour among elementary school kids? So wrong, yet so... funny! If you enjoyed the intense sexuality-based comedy in Rizelmine, you may like what Kyou no Go no Ni has to offer. Both anime are hilarious and just plain silly. There are romance aspects, but they aren't very heavy. Kyou no Go no Ni has more one-shot stories, and they really exaggerate the art aspects such as funny facial expressions and "sexy details", while Rizelmine follows a storyline.
