What will you do when you find out that everything that you have learned and knew about the world is a string of lies? Thats exactly what happened to 17 year old high school student named Ayato Kamina, however, everything is about to change when a mysterious civilization called "MU" invades his home. Raining destruction from the sky in mysterious monsters called Dolems. The next events that occur will lead Ayato and a mysterious girl named Reika Mishima, to the truth of their existence, the discovery of what and who he is, and to the powerful angelic robot called RahXephon.
The plot and story line of RahXephon is hard to follow and understand if you dont put enough focus to it. You can also consider RahXephon to be similar to the revolutionary Neon Genesis Evangelion in terms of Robot combat actions and weird Sci-fi scenes. However, once you understand the whole story and starts to make sense you will then find out that this anime is not your average everyday anime.
