Nagato
Nagato was born in Amegakure, a village hidden in rain, to a family of farmers. He was a sickly child, and his parents died when he was very young. He was then taken in by Jiraiya, a legendary ninja from Konohagakure, who taught him the way of the ninja.
Nagato was a brilliant student, and he quickly mastered the art of ninjutsu. He also developed a strong sense of justice, and he dreamed of one day creating a world where everyone could live in peace.
However, Nagato's dream was shattered when he witnessed the death of his best friend, Yahiko, at the hands of Hanzo, the leader of Amegakure. Nagato was filled with rage, and he vowed to avenge Yahiko's death.
Nagato joined forces with Konan and Yahiko to form Akatsuki, an organization dedicated to world peace. However, Nagato's methods became increasingly violent, and he eventually came to believe that the only way to achieve peace was through the use of force.
Nagato's actions led to the deaths of many innocent people, and he eventually came to realize that his path was wrong. He sacrificed his own life to bring about peace
