Naruto: Becoming the Jinchūriki of the Hundred-Tails Sister

Li Yan transmigrates into the world of Hokage and binds himself to the Strongest Jinchūriki System. Others have at most ten tails, but you have a hundred? What? The Hundred-Tails is actually a little sister, and she even got into a fight with the Nine-Tails. Golden chakra, and she starts off with cheat-level powers? One can take on nine, and she evolves straight into the Sage of Six Paths, with a miraculous fusion technique that completely outclasses the Six Paths of Pain. In the blink of an eye, the little Hundred-Tails grows into a gorgeous big sister. I look forward to working with you, Big Sister Hundred-Tails.
