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.
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 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.
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.
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.
Yes. Fanfiction writers often like to play with the established relationships in the Naruto series. While it may seem strange at first considering the time differences and the original pairings in the series, in fanfiction, it can work. Writers can create interesting stories around this pairing, such as how Naruto would deal with the responsibilities that came with being Mito's husband in her era.
In a fanfiction plot, Naruto might be in a coma or a state of near - death. His friends try everything to bring him back. Then, suddenly, Naruto starts singing 'Bring Me Back to Life' from within this state. His voice somehow reaches the living world and has a magical effect. It could start to heal the wounds of the village, both physical and emotional. His friends then have to find a way to fully bring Naruto back to the living world while he continues to sing, creating a bond between the two worlds that was previously thought impossible.
Yes, in some fanfictions, Naruto is depicted as the reincarnation of Mito. Fanfiction writers often like to create such unique connections to add new twists to the story. It gives a whole new dimension to Naruto's character and his connection to the Uzumaki clan's history.
The main antagonists could be a group of rogue ninjas who are after the secrets of the Uzumaki clan. Since Naruto is Mito's brother, they might target him to get to those secrets.
