I Just Want to Protect Those Two

Summary
After the Second Great Shinobi World War, Jiraiya began training the Ame Orphans. Although it was partially to help them look after themselves, it was also to teach Nagato to take advantage of his Rinnegan. Since Jiraiya wished for peace, he hoped Nagato, having the same eyes as the Sage of the Six Paths, could unite the world just as the Sage had. Nagato and the other orphans accepted this quest when Jiraiya left them and spent their adolescent years preaching an end to war. Hanzō, leader of Amegakure, interpreted this as threat to his rule and kidnapped Konan. He then gave Nagato a choice: kill Yahiko or sacrifice Konan. So that Nagato would not need to make the choice, Yahiko killed himself, entrusting Nagato with their dreams of peace. Having lost a friend, Nagato concluded that diplomacy would be useless in obtaining world peace.
