[Naruto] to Cure the Second Disease, Finding the Root Cause Is the Key

Ambitious people are scary. A strong and ambitious person is even more terrifying. There is nothing more terrifying than a chuunibyou patient who is ambitious and capable. What if this ambitious and capable chuunibyou patient is a younger brother? … ... Forget it, let's go to bed. If Boss Madara's brother was sent back to him, if Obito's little boss had not been brainwashed, he knew that he had misunderstood his gay friend, if Yahiko hadn't died... Then everyone will not go back to the second grade and never come back~ Therefore, when it comes to treating secondary disease, finding the root cause is the key = =+ The sudden appearance of Izuna in this article is not a time travel, and it cannot be completely regarded as a rebirth. Don't worry about how Izuna came back to life, because the author doesn't know either_(:з∠)_ In addition, Izuna-kun in this article is neither gentle nor blind. Saving the world is what the blond-haired protagonist does. He just wants his brother to be safe. Well, I think I wrote about Uchiha Izuna according to my own understanding. Please forgive me if you have different opinions. In fact, it cannot be regarded as Xipiwen in the strict sense. It can also be viewed as something like a brotherly love and old companionship (wrong!). When writing this article, the original work has not yet been completed, so there will be bugs in the settings. Just treat it as a parallel world and don't delve into it. Conception:
