The reborn boy Orochimaru combines his past life memories and lifelong knowledge to return to Konoha's youth before the turmoil. He is familiar with all the plots and underlying rules of the ninja world, abandons the paranoid obsession of the original work, and sees through the structure of the ninja school with a cold eye. He inspired Jiraiya, the last man in the world, and polished Tsunade's talent. He crushed his peers with his ultimate chakra control, broke the tragic fate of the three of them, and quietly laid out plans on the eve of the war to rewrite the future of the ninja world step by step.
