In the war-torn Konoha Village, five-year-old Orochimaru was reborn here with memories of his past life. His parents were killed in the war, and he lived alone in a deserted wooden house. He looked cold and quiet, but he was recognized as the top grader in the ninja school. The genius boy in the eyes of others has already understood the fate of the "Sannin" in the future, and has always remained alienated from his surroundings.
One night late at night, he bumped into Jiraiya the crane tail who was training hard but couldn't figure it out. Seeing that the opponent was overstretching his body through training and was unable to escape the fate of repeating the grade, he changed his alienated attitude and customized a ninety-day training plan, from body building to chakra sprinting, step by step to get Jiraiya back on track.
In the graduation examination, Orochimaru amazed the audience with his exquisite tactics, Jiraiya successfully passed the test with his counterattack performance, and Tsunade emerged with her strange talent. The bond between the three people, who were originally destined to go their separate ways, quietly took root in their youth. The granddaughter of the Hokage, the orphan at the end of the crane, and the reborn genius boy, in the smoke-filled Konoha, jointly opened the prologue of their ninja.
