Well, in this fanfiction, an ending might be that Hinata, in her grief, leaves the village for a while to find herself. When she returns, she has become stronger and more confident. She then devotes her life to making the village a better place, just as Naruto would have wanted. Another ending could be that the whole village unites even more tightly after Naruto's death, with Hinata at the forefront of this unity, as she was the last person Naruto protected.
He would feel a deep sense of guilt, thinking that if he had been stronger or more aware, he could have saved her. Naruto might also start to cherish the memories he had with Hinata more, and this could change his personality a bit, making him more somber at times. He would probably vow to protect the things that Hinata held dear, like her family and the village.
In this type of fanfiction, Naruto's death while protecting Hinata could be the turning point of the whole story. It could cause a shift in the power dynamics of the village. Hinata, on the other hand, would be deeply affected. She might become more withdrawn at first, but then gradually find the strength within herself. His death could also inspire the younger generation to be more like Naruto, always ready to sacrifice for the ones they love.
There could be. Fanfiction is a vast and diverse world where all kinds of crossovers and unusual plotlines can exist. However, considering that Naruto and Bleach are two separate and distinct anime universes, it's not something that would be part of the official storylines. But fans often create unique scenarios, so it's possible that someone has written such a fanfiction, though I haven't come across it myself.
One possible plot could be that an ancient evil is awakened and sets its sights on destroying Konoha. Naruto, as the Hokage or a respected ninja, rallies all his friends and allies at first. However, as the battle progresses, he realizes that the only way to truly stop this evil is by giving his own life. So he makes the ultimate sacrifice, using his chakra to seal the evil away forever, thus protecting Konoha at the cost of his life.
One possible plot could be that Naruto and Haku are in a situation where an extremely powerful enemy attacks. Naruto, being the selfless hero, jumps in front of Haku to take a fatal blow. Haku is then left with the guilt and determination to carry on Naruto's will. She might vow to bring peace to the ninja world, just as Naruto had always dreamed. This could lead to Haku joining the Hidden Leaf and trying to bridge the gap between different ninja clans in Naruto's memory.
He would be filled with rage. Naruto has a strong sense of justice and the fact that someone took Hinata away from him would fuel his anger. He would vow to find and punish whoever was responsible. He might even become reckless in his pursuit of vengeance, endangering himself and those around him. His friends would have to step in to try and bring him back to his senses.
Well, it would be a massive shock to the Naruto universe. Naruto was a key figure in promoting peace and unity. With his death protecting Ino, there could be a resurgence of old rivalries. Ino, on the other hand, would be forever changed. She might struggle with survivor's guilt at first. But over time, she could become a force for good in her own right, using Naruto's memory as a motivation. His death could also inspire other characters to reevaluate their relationships and what they are fighting for.
One possible fanfiction plot could be during a village invasion. Naruto, with his unwavering sense of justice and his growing feelings for Hinata, shields her from an enemy's attack. He might get seriously injured, which then spurs Hinata to tap into her own hidden power to defend him in return. This kind of story can explore their bond deeper and show how they support each other in tough times.
The appeal lies in the potential for romantic development. In many fanfictions, Naruto protecting Hinata is a stepping stone to their romantic relationship. It creates a lot of tension and sweet moments. Naruto's heroic acts make Hinata admire him more, and Naruto starts to see Hinata in a new light. These stories can also show how their relationship affects the other characters in the Naruto world and the overall story arc of the fanfiction.
