Naruto Namikaze Minato Brothers.
Nagato is similar to Watergate. Who first became a believer in Jiraiya? If we start with the battle of patience! In the Second Endurance World War, Jiraiya, orochimaru and Gang Shou were called "Three Endurances" by Shimada Hanzo in Rencun. Although the strength of the three has not yet formed, they also have the strength close to the film level. Nagato, Yahiko and Xiao Nan became Jiraiya's apprentices at that time. After the second protracted war, Jiraiya taught Nagato and others for three years before leaving Rencun.
After that, he returned to Muye, where he accepted Watergate as an apprentice and founded the Jiraiya team. After the Watergate incident grew up, it became a yellow flash that frightened the forbearing world in the third forbearing world war, ending the third forbearing world war. From the perspective of forbearing the world war, Nagato is the brother of Watergate.
However, we have forgotten a very important person-bringing soil. In the third Ninja War, Yahiko died and Nagato was hacked because of the instigation of Dai Tu. Tui is a disciple of Watergate, ten years younger than Watergate. Nagato died at the age of 35, and a year later, Dato died at the age of 33 in World War IV, which showed that he was four years younger than Nagato. In other words, Watergate was ten years earlier than Nagato. In this case, this is the first time that Jiraiya admitted Watergate. It can be seen that Watergate is Nagato's brother.
