The truth behind the Rinīnegan:
In chapter 373 the Rinīnegan was introduced as the third and most powerful doujutsu in the Naruto series.
One of Jiraiyaīs students, Nagato, surprisingly achieved it and killed a foreign chuunin.
In the same chapter we learned about the Rikudou Sennin (sage of the six paths). According to Jiraiyaīs statement he also possesed the Rinīnegan and had also been the founder of the ninja world and ninjutsu itself.
In the following chapters we saw Jiraiya fighting Pain, the possible leader of Akatsuki. He possesed the Rinīnegan but we couldnīt really see him using it in the battle.
In that fight we saw six different bodies. They all are said to belong to Painīs mind. All of those bodies look like shinobis Jiraiya, Tsunade and Orochmaru had met before, probably in the second ninja world war and one of the bodies looks like Yahiko, another one of Jiraiyaīs students and a friend of Nagato.
Right before Jiraiya sank into the waters of Akatsukiīs hideout, he wrote a message on grampa frogīs back: 9, 31, 8, 106, 7, 207, 15.
He told grampa frog to deliver this code to Tsunade, to tell her the true identity of Pain.
This entire story about the Rinīnegan brings up many questions:
Who is Pain?
What is the code on grampa frogīs back supposed to mean?
Who is the sage of the six paths?
Are those "six paths" somehow connected to Painīs six bodies?
What are the powers of the new doujutsu?
Also interesting in my opinion is that Pain said right after the battle was over: "If we havenīt kept our secret, we would never have won."
Did he mean the secret of his identity?
Letīs discuss about all this in this thread. I want to here your opinions and theories.
Iīm looking forward to it.
