After his parents were killed, Yahiko met two other orphaned children, Konan and Nagato. While on their own, the trio would do what they could to survive. One day they met the Sannin, who were returning to Konoha after the end of the war with Rain. Yahiko asked the Sannin for food and begged the Leaf to teach them Ninjutsu. Orochimaru suggested killing the youth then and there, as their life would only be filled with pain in the future. Jiraiya said absolutely not, and offered to look after them for awhile. After settling in to a small cottage, Jiraiya began to feed and watch after the children. When Nagato began to imagine how much like his family life his new surroundings were, Yahiko yelled at him in anger to man up, as crying gave off a bad impression of Rain country boys. Yahiko went on to argue that the only way for the conflict surrounding Rain to end, would be if everyone experienced the same pain they went through. Yahiko promised to protect his friends and reiterated his request for Jiraiya to train them.

Later that night Yahiko and Nagato were attacked by a refugee from Hidden Rock. Nagato used his Rinnegan in self-defense and quickly killed the attacker. Jiraiya was shocked by the appearance of the legendary Doujutsu and finally agreed to train them. Over the next three years Jiraiya taught the youth Ninjutsu. When the trio finally managed to defeat one of his Kage Bunshin, he let them know their training with him as ended. He wished them well and the trio remained behind to do what they could to help their country. The orphans would fight many battles and Yahiko would apparently fall in one such conflict. Konan and Nagato would continue on with their goal of changing Rain and the world, as Akatsuki members. Nagato himself would change his name to Pain and make his life goal to honor Yahiko's desire that the world feel the same pain they once felt.

Yamato is connected to the legacy of Shodai because he carries his genes within him. When Orochimaru was still a respected ninja within Konoha, he carried out experimental gene therapy on 60 village children.

His group then pursued Orochimaru thanks to a tracking seed placed in Sai. Though they successfully infiltrated Orochimaru's compound and found Sasuke, the meeting did not last long. Before Yamato had a chance to get serious, the Sound ninja fled.
