In the fanfiction, Naruto might die while saving Boruto from a self - destructive power within Boruto himself. Perhaps Boruto has been corrupted by some dark force and Naruto has to use his own life force to purify Boruto. This would create a complex emotional arc for Boruto, who would then have to live with the guilt and the responsibility of living up to Naruto's sacrifice.
One possible plot could be that Naruto sacrifices himself to protect Boruto from a powerful new enemy. Maybe an ancient evil has been awakened and Boruto is in its direct path. Naruto, being the hero he is, steps in and uses all his power to stop it. His death then becomes a catalyst for Boruto's growth, driving him to become stronger and more determined to protect the village in Naruto's memory.
Perhaps there's a prophecy involved. The fanfic could be set up where it's foretold that Boruto will bring about a great change, but only if he survives a certain threat. Naruto, aware of this, sacrifices himself to ensure Boruto lives on. This could then trigger a series of events where Boruto has to deal with the political fallout in the village, as some may blame him for Naruto's death, while others see him as the key to the future. It could also lead to a rift between Boruto and some of his friends who struggle to understand why Naruto had to die for him.
One possible plot could be that Naruto sacrifices himself to save Boruto from a powerful new enemy. Maybe an ancient evil resurfaces that is too strong for Boruto to handle alone, and Naruto steps in, using up all his chakra and ultimately dying in the process.
Perhaps the village is invaded by a horde of powerful demons. Naruto, after a long and grueling battle, realizes that the only way to stop them is to seal them all away, like the way the Fourth Hokage sealed the Nine - Tails. But this sealing jutsu demands the life of the caster. Without hesitation, Naruto performs the jutsu, sacrificing himself to save the village he loves so much.
Boruto's reaction would be complex. He'd be heartbroken, for sure. He might start to question his own worth and purpose. But over time, he'd realize that he has to carry on Naruto's legacy. He'd become more serious and focused. He'd also become more empathetic towards others, understanding the weight of sacrifice. He might even start to study Naruto's techniques and leadership style more closely, trying to emulate the things that made Naruto such a great Hokage and hero.
In such a fanfiction, one possible plot development could be that Naruto sacrifices himself during a major battle against an extremely powerful enemy. Maybe an enemy that has the power to destroy the entire Hidden Leaf Village. Naruto, being the hero he is, steps in to protect Hinata and in the process, takes a fatal blow meant for her. This would lead to great sorrow among the villagers, especially Hinata who would be heartbroken. She might then vow to carry on Naruto's will and protect the village in his memory.
In the 'naruto dies boruto fanfic', it could be that Naruto is killed by an unexpected betrayal within the village. This shatters Boruto's world. He then goes on a journey to find out the truth behind the betrayal. Along the way, he meets some of Naruto's old friends who help him train and grow stronger. Boruto also starts to uncover secrets about the village's past that his father was trying to protect, and he realizes he has to be the one to expose these secrets and bring justice to his father's death.
At first, Boruto would be in shock. But then, he would likely be filled with a new - found determination. He would vow to become as strong as Naruto, if not stronger. He'd study Naruto's techniques more intently and strive to protect the village in Naruto's place. Boruto would also carry the weight of Naruto's legacy on his shoulders, which would shape his actions and decisions in the fanfiction.
It could be a new character entirely. Maybe a rogue ninja from a long - forgotten clan who holds a grudge against Naruto for some past event. This villain could be extremely powerful in dark jutsu and sees Naruto's death as the first step in his plan to take over the ninja world.
One possible plot could be that Naruto and Kakashi are in a fierce battle against a powerful enemy. Kakashi is about to be fatally attacked when Naruto jumps in front of him and takes the hit. As Naruto is dying, he might have some final words for Kakashi, perhaps about the importance of protecting the village and their friendship.
Well, it could be a story where Karin has some knowledge about a strange phenomenon that's starting to affect Boruto's chakra. Naruto, as a protective father, gets involved. Karin might be the key to unlocking the mystery behind it. Maybe she has a personal vendetta against an old enemy who is causing this, and Boruto and Naruto end up helping her while also protecting the village from the potential danger.
