Nagato was an of naruto lineage and he got rinne so why is it far fetch for naruto to get itAbout as likely as rinnegan Naruto.
Trust me he will, have have mastered utilizing natural energy without the curse markI hope he does.
No, he got it from JugoOrochimaru wanted Sasuke Body so He put His curse Mark on Him as parted way to control Sasuke,So why would Orochimaru teach Sage Mode to Sasuke? It defeat the hole purpose of the curse mark,put Sasuke out of His control. And sines Sasuke Kill Orochimaru Sasuke ben on the move,He has not had time to learn any Sage Mode. So were is He getting it from? His Fairy Godmother?
