The Sage of the Six Realms according to Naruto 446 was
- the first to divine the true meaning of chakra and tried to lead the world to peace
-his religion (probably the ability to manipulate chakra) later developed into Ninja techniques
-he has Rinnegan like Nagato
-he is quoted to have said," I am here to provide Peace and Order'
-as of the moment, nothing is ever heard of this Sage of the Six Realms
The Sage of the Six Realms looks like an akatsuki member based on his silhouette. Not much information is provided about him and where he is now - maybe in the following chapters of the Naruto saga (Japanese manga or comic book to noobs).
Why did it take two weeks to release this Naruto chapter?
There was a festival in Japan last week so no Weekly Shounen Jump. It was a holiday get it? It's not like it was done on purpose to piss fans off. Geesh. Some anime fans need to grow up.
If the Naruto story is getting old, you're getting old with it. Hard to admit for some people but it is the truth. Just enjoy the manga dude!
Based on personal observation, Danzo could be Naruto's most hated character at the moment displacing Nagato after the latter's sob story. Danzo is the mastermind of the extermination of a certain clan in Konoha and he is now the "last straw" so to speak that turned Nagato against Konoha. How quickly can fans turn against a character eh? The good thing is Sasuke is now looking for him.
I'm not that affected though. My most hated anime character is Suzaku Kururugi - the hard headed and pea-brained character in Code Geass. The good thing about him is he doesn't even know he's bad.
