jiraiya the toad sage
Naruto becomes a sage after he finds out that the pervy sage had died nd the elder frog that trained him uses toad oil and naruto becomes a sage he uses this power to fight pain,
It is unclear whether the fourth even was a sage or not. If he was, it would be safe to assume that Fukasaku and Shima were his safe toads.
no jiraiya is he is one of the three sannin (shinobi three) however he does teach naruto some toad jutsus and naruto becomes a toad sage.
they won't give it to you cause they dislike you
