The Younger Son of The Sage of Six Paths is the youger son of the Sage of Six Paths. He inherited the Sage's "body" — life force and physical energy — and believed that love was the key to peace. When the Sage was on his deathbed, he selected the younger brother to carry on his dreams of peace for the ninja world. The older brother, believing he should have been chosen, fought him to try and claim what he felt he deserved. The descendants of the elder brother, who would become the Uchiha clan, would continue this fight with the younger brother's descendants, who would become the Senju clan.
