Naruto manga i need a summary of wht has happend so far and wht is the chosen one and rinnegan?

As the Great Sage says, The Chosen One is the one who will bring peace and balance to the world OR bring chaos and destruction to the world and it is up to Jiraiya to make the decision for it is said that he will train this particualr 'chosen one'. The manga did not yet show any certain character that will be the chosen one and is still a mystery. But my guess is either Pein or Naruto.

Rin'negan is a doujutsu, an eye jutsu. It is also a bloodline but the clan was extinct and only Nagato has it. Nagato right now is Pein/Pain, who is the leader of the Akatsuki.

i dont know about the chosen one but pain has the rinengan and jiraya battles him and pain has 6 forms and jiraya kills 1 of them and sends the body to tsunade with one of the toads (hes in hermit mode) jiraya dies right after he figures pains true identity and then dies and he gets flash backs and then he remembers narut saying "ill never give up" so Jiraya comes back to life by will power and gets chakra to his finger and gives the information about pain to his other toad and then pain kills jiraya while the toad escapes

the chosen one is the destined child the one who will bring destrution to the world or peace and of course it turns out that naruto is the one. and the rinnegan is a very powerful eye just like the sharigan and the only one wit it is pein(pain) and jiraya dies so sad and he is the one who gave naruto his name and we see 4 the frist time naruto's mom its cool u should read it <">

rinnegan is a bloodline limit ability...much like sharingan and byakugan
