Naruto: Becoming Tsunade's Brother and Researching Forbidden Jutsu in the Shinobi World

My younger sister is a delicate woman with Medical Ninjutsu beyond Hashirama's reach, but she can't even use Wood Release. Madara called Princess Tsunade ugly to her face. How can anyone bully my little sister? The Shinobi World War, the Cloud, the Wind, even Madara himself: all of them will kneel at my feet. You ask why I'm so damn strong? Because I'm a reincarnator, the chosen one!
