I've read through the manga again and ive found something a bit strange...but i'm not sure about it... When Jiraiya was teaching rasengan to naruto he said that if u master that technique you would be the 4th user of this jutsu... The first one is the yondaime(the forth hokage) the second is jiraiya the third is... the fourth is naruto>?? have i not well understood what jiraiya said or else there is another user of rasengan other than jiraiya,naruto and the fourth... Could anyone confirm this to me???
