When Naruto was in the Uchiha family, he devoured Naruto and obtained nine tails. The title of the book could be called " Nine-Tailed Demon Fox: Uchiha Sasuke." The title combined the elements of Nine-Tailed Fox and Naruto to describe the process of the protagonist obtaining the nine tails and finally becoming a powerful ninja.
