Perhaps Naruto and Hinata are on a mission together. They get ambushed by a group of rogue ninjas with some new, unknown and deadly jutsu. Naruto, seeing Hinata in immediate danger, uses his own body as a shield. His death would then trigger a series of events in the village. The villagers might start to question their security measures. Hinata, on the other hand, could be so stricken with grief that she isolates herself at first, but then slowly realizes she needs to be strong for Naruto's sake and for the village.
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 this fanfiction scenario, Naruto might die while saving Tsunade from a sneak attack. His death could cause a shift in the power dynamics of the village. Tsunade, filled with guilt and grief, could then take on a more reclusive role. Meanwhile, the younger generation, seeing Naruto's selfless act, would strive to uphold his ideals. They might start training harder and be more committed to protecting the village, just as Naruto did.
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.
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.
Well, one possibility is that they'll start to understand each other on a deeper level. Maybe Hinata will help Naruto with his daily chores and they'll share some really cute moments together, like cooking meals and having dinner by the window. They might also have some awkward yet sweet encounters as they adjust to living together.
One possible plot could be that Naruto sacrifices himself in a great battle against an ultimate enemy. Hinata, who has deep love for Naruto, is devastated. She might cry inconsolably as she remembers all their moments together, from when she first noticed him as a child to their more recent interactions. She could also vow to carry on Naruto's legacy in the village, while mourning his loss privately.
One possible plot development could be that Naruto sacrifices himself to save Ino from a powerful enemy. This might lead to a great sense of guilt among the other characters, especially those in Naruto's circle. Ino herself might be forever changed, vowing to carry on Naruto's will in some way. She could become more determined to achieve peace in the ninja world, inspired by Naruto's selfless act.
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.
Well, one possible plot could be that Naruto and Hinata finally get some time alone after all the chaos in the ninja world. They might have a romantic getaway and during that time, Hinata discovers she's pregnant. This could lead to Naruto being over the moon but also super protective, like he'd start taking on fewer dangerous missions to be around for her.
Well, one possible plot development could be that Naruto and Hinata face various challenges as they prepare for the arrival of their baby. They might struggle with how to balance their ninja duties with family life. For example, Naruto may have to go on important missions while Hinata is pregnant, causing some tension between them as she worries about his safety. Also, their friends in the village could be involved, like Sakura helping Hinata with her prenatal care. The story could also explore how the village as a whole reacts to the news, whether they are excited for the new addition to the Uzumaki - Hyuga family or if there are some political implications due to Hinata's Hyuga lineage.
One possible plot reason could be for Naruto to experience a great loss that changes his character completely. Maybe it's part of a dark plot where the enemy is so powerful that they manage to kill Hinata right in front of Naruto. This would fuel his rage and determination to become even stronger and seek revenge. Another reason could be related to some sort of sacrifice. Hinata might sacrifice herself to save Naruto or someone else important, and Naruto has to deal with the guilt and grief of her death.
