Some of the shinobi who are more traditional in their beliefs may oppose Naruto. They think that death is final and interfering with it could anger the gods or spirits. They may also fear that Mito, being from a different era, could bring with her old - fashioned or dangerous ideas that could divide the village.
One possible plot could be that Naruto discovers some ancient and forbidden jutsu. He decides to use it to bring Mito back to life in order to gain more knowledge about the Uzumaki clan. Mito then helps Naruto understand some hidden powers within the clan and they together face a new threat to the village.
One consequence could be that it messes with the natural balance of the ninja world. Maybe the cycle of life and death is disrupted, and this causes some strange phenomena to occur, like abnormal weather or chakra imbalances.
It's not really possible within the normal Naruto lore. But fanfiction is all about exploring 'what ifs'. In a yaoi fanfiction where Naruto brings Itachi back to life, it could be based on some extreme emotional bond. Maybe Naruto discovers a hidden power within himself that he can use to reverse death. But this goes against the established rules of the Naruto world where death is usually final. So, it's really a matter of the author's creativity and how they can justify such a huge event within the framework of the Naruto world, even if it's a yaoi - inspired take on it.
In certain fanfic ideas, Naruto could have made a deal with some sort of otherworldly being. He might have sacrificed something of great value, like a part of his own chakra or a future ability, in exchange for Kushina's life. Another possibility is that he finds a way to reverse the very nature of death by using some unique properties of the tailed beasts' chakra that he has access to.
One possible plot could be that Naruto discovers a powerful and long - forgotten jutsu that has the ability to revive the dead. He decides to use it on Itachi. Once Itachi is back, they join forces to stop a new, powerful enemy that is threatening the ninja world. Itachi's skills and knowledge, combined with Naruto's power, make them an unbeatable team.
One possible plot could be that Naruto, consumed by his love for Itachi (in a yaoi sense), embarks on a journey to find a way to bring him back. He might encounter some ancient and forbidden jutsu that has the power to resurrect. Along the way, he has to face many challenges and enemies who oppose his plan. Once he brings Itachi back, they then have to deal with the consequences of defying the natural order of life and death in the Naruto world, and also explore their new relationship.
Here are a few recommendations for novels that bring memories back to life:
1. "Rebirth: The Immortal Poison Thief": It described how the main character, Xiao Yan, had been reborn five years ago. He possessed the memories of the previous game and faced the challenges from other reincarnators and assassins. He had to advance steadily and walk his own path.
2. " Virtual Realm Master of Online Games ": The protagonist of this novel is a famous female game streamer who was tricked into playing a completely stealth game called " Nightmare ", only to realize that this game was designed for her, so that she could defeat the many strong players in the game.
3. [Upgrade-Against-The-Sky]: The story of the Potioneering Grandmaster Xin Lang who was reborn twelve years ago after he died for his lover. He changed his fate through an all-rounded Upgrader.
4. " Rebirth, Counterattack, There's Space ": The female protagonist was reborn with the space of inheritance and rich materials, determined to balance the regrets of her previous life.
5. The protagonist, Chen Bei, brought the memories of his previous life and unfolded his life trajectory.
These novels all had elements of memory rebirth and were suitable for readers who liked this kind of theme.
Yes, there are likely such fanfictions. Many fanfiction writers like to explore the idea of Itachi coming back to life with his memories intact. This allows for interesting character interactions, especially with Naruto. Itachi could use his wisdom and skills once again, and his relationship with Naruto could further develop in new and unexpected ways.
Redemption is also a big theme. Sasuke is often seen as a lost soul who needs to be redeemed. Naruto's efforts are not just about bringing him back physically but also about saving his soul. For example, in many fanfictions, Sasuke has done some bad things, and Naruto is there to make him see the right path again.
