In this fanfiction, it could be that Naruto's sister is being targeted because she has information that could expose a powerful and corrupt group. Naruto, being the selfless hero he is, shields her from their attacks. His death becomes a symbol of resistance against this group, and his sister then takes on the task of bringing them to justice.
The Hidden Leaf Village would be in deep mourning. His friends like Sasuke would be filled with a mix of anger and grief. They might vow to protect Naruto's sister in his memory. The village would also probably hold a grand memorial for Naruto, and his story would become a legend to inspire future generations of ninjas.
In the Naruto series, Naruto doesn't have a biological sister in the original story. So in this fanfiction, the author probably creates a new character to be his sister. It could be an original character with unique abilities and a complex backstory that leads to the situation where Naruto dies by her hand.
In such a fanfiction, Naruto could die in various ways. Maybe his sister is somehow possessed and attacks him fatally. Or there could be a situation where she accidentally causes his death during a fight due to a lack of control over her power.
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.
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.
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.
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.
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.
