Back then, Jiraiya went to Mt. Myoboku and heard the big toad's prophecy about "the green-eyed boy who laughed and called the name of the nine-headed beast." He thought that this boy was Naruto, and that the son of the prophecy would give the entire world Bringing reform to the ninja world, Naruto is his apprentice and a ninja from the Land of Fire.
The son of the Fourth Hokage, and the nine-tailed fox was sealed in Naruto's body. At first he was ostracized by the people in the village, but later he, Kakashi Hatake and Sasuke Uchiha, Haruno Sakura formed the seventh team, constantly upgraded to fight monsters, became recognized as a ninja, and became a disciple of Jiraiya. In various tasks, he became more and more powerful, and later ended in the final war. With his fighting power, he brought peace to the ninja world and became the real Hokage himself.
I think the reason for Jiraiya to judge that Naruto is the son of prophecy is mainly because Naruto has the seal of the Nine-Tails in his body, and he is the descendant of the Fourth Hokage. In Jiraiya's heart, Naruto has the potential to reform the ninja world, so Jiraiya believes that Naruto is the son of prophecy.

It mainly tells the inspirational story of Naruto becoming a Naruto from an inconspicuous little person, which can even be said to be the last one. This story is not only There are many complicated backgrounds and a lot of foreshadowing. Naruto also gained friendships, powerful abilities, etc. in various tasks.
