In the muddy Land of Rain, Nagato Uzumaki suddenly opened his eyes. The rippling pattern of the Rinnegan gleamed coldly in his gaze. Carrying the memories of someone who had transmigrated, he resolved to escape his tragic fate. Following Jiraiya into Konoha, the warm and gentle young man made protecting his comrades his creed. He displayed astonishing strength in the ninja wars, earned the Third Hokage's trust, and surged forward toward the Hokage Position.
Then everything took a turn. One day, while Nagato was training, a five-year-old Uchiha girl with long black hair clung to him, tugging at his clothes with a soft little hand and asking in a childish voice for guidance in the Body Flicker Technique. Nagato patiently taught her step by step. Then he casually asked her name, only to be jolted when the little girl clearly answered, "Shisui Uchiha." He was so startled that the kunai in his hand nearly fell to the ground.
