I watched the chinese sub of Aquarion 5 mins ago.
I agree with Renato. It's the best damn anime on TV at the moment. From the quality of the animation, I think Bandai put a lot of money into this anime. And, Mr.Kawamori is doing a great job with it.
Setting: Two very advanced ancient civilizations, "The Angels" and "The Fallen Angels", fought each other in a war long long time ago. At the end, The Fallen Angel lost the war...
However, Fallen Angels reappear in the 21st century to conquer earth for something they want.
Humans had no chance againist them because Fallen Angels can produce *some sort of music* to steal human bodies and souls as weapons.
One day (not sure when), a scientist/achaeologist found Aquarion in a ancient ruined site. He found out that Aquarion is a giant robot that The Angel used to fought The Fallen Angels and the Angels are *reincarnated* into some of the humans... (reincarnated is not that right... it is more like having The Angel's DNA and memory in a human body. Ep01 didn't say too much about it.)
and guess what... the main male character is the rebirth of the great Angel warrior, "The Wing of Sun" and the female character is the rebirth of the Angel's princess.
