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.
"I have only abandoned my body, I still live here" - are the words emailed to friends of Chisa, several days after her death by suicide. As Lain delves deeper into the world of the "Wired" (also known as the internet), the line between it and reality becomes more and more unclear. Close the world, open the nExt.
Lain provides a similar "What just happened?" feeling throughout the story. Just when you think that you understand what is going on, you find out that you are wrong. An intense, mind-blowing experience.
Both series deal with philosophical questions. If you liked one because of interesting thoughts about our reality and about our existence, you would surely like the other. Both series are difficult to understand and have to be seen more than once, because there are several points of view.
What do a timid fourteen-year old girl and a giant robot with the wings of an angel have in common?
Well ok. Nothing. Still, both Rahxephon and Serial Experiments Lain are similair in the sense that they both deal with philosophical and existential themes while at the same time not shying away from totally messing with the viewer's head.
Ayato and Lain also go through similair developements and dilemmas regarding themselves and their view on the world in general. Ultimately though, they come up with different solutions for how to handle their respective situations.
So in short, if you liked one of these series because of the great sense of mystery and thought-provoking plot and fantastic use of symbolism and cultural (in Lain's case) or historical (in Rahxephon's case) references, check out the other series. There's a good chance you'll love that as well.
Kazuki Yotsuga is able to see things that others can't; in his visions, giant robots battle it out in the streets, causing massive damage in their wake. Though his visions have made him an outcast from the rest of his peers, they have attracted the attention of Ken Sanada – a physicist who believes Kazuki’s visions are a gateway into a parallel world! He places Kazuki into one of his inventions and accidentally sends him to the parallel world in his visions, where he finds himself in the middle of a war for control of the world! Kazuki must now become a pilot of one of the robots in order to join the fight for peace, all the while trying to find his way back to his own world…
Rahxephon and Dual! Parallel Trouble adventures are both outstanding examples of the harem comedy genre combined with secondary mecha/war elements. Both Ayato of RX and Kazuki of Dual are fairly likeable male leads who aren't quite as wimpy as similar characters in other shows. RX and Dual also feature a diverse cast of female characters, with an assortment of appearances and personality types. If you can find a girl to like in one show, you can find a girl to like in the other.
Both RahXephon and Dual! Parallel Trouble Adventures are post-NGE series. Both of them a lot of elements from Neon Genesis Evangelion and because of that both of them resemble each other. Dual! Parallel Trouble Adventures has a harem going on, on the other hand RahXephon has only a hint of that. While both series are lighter on drama than Neon Genesis Evangelion, RahXephon has considerably more drama than Dual! Parallel Trouble Adventures (which lacks it almost completely). Also, RahXephon has way better written story and characters, though due to strong similarities between those series you might still want to check one if you've seen the other one.
Gonzo does it again with this action-packed mecha comedy. She's an ordinary high school girl. He's a counterterror agent assigned to protect her from those who would steal the information locked in her mind. OK, so she's not so normal after all. Armored Slave battles and lovers' spats abound as Sousuke and his comrades try to track down the mysterious Gauln before it's too late.
While it might seem weird at first to recommend FMP for RahXephon, the idea popped into my head based on the fact that while though they both have mecha, they also have a very large storyline apart from the major fighting machines. Full Metal Panic and RahXephon are alike in the fact that the characters have lives and stories outside of fighting.
Both anime's bring together a strange male/female duo whose relationship gets strange as the truth is revealed about the abilities and responsibilities of the characters.
The mecha fighting is similar though the animation is worlds apart. So if you enjoyed the type of story that one anime brought to the table, you are sure to like the other
End of Evangelion is an alternate ending to the Evangelion TV series (replaces episodes 25/26). In this powerful conclusion, the final battle against the Angels is fought, and questions are finally answered. The fate of the world lies with Shinji, but how will he act?
If you haven't watched Neon Genesis Evangelion first, do so. This is the END of it, hence the title. But, the whole imagery and idea behind the End of Eva is very similar to that of the end of RahXephon.
In the world of Prestal, Noble men perform noble deeds for noble purposes. All of this is performed under the careful gaze of the Guild, a race apart who live in cities in the sky. We see this world through the eyes of Claus Valca and Lavi Head, as their travels take us above, beyond and through Prestal, and their actions cause ripples that shall never fade.
I can't tell why, but RahXephon and Last Exile felt quite alike (honestly I can't name what made me think so). So, if you liked one, you might enjoy the other one as well (but you'll have to trust my gut fell on that).
