The other ninja from different villages would also react. Some might see Naruto's sacrifice as a noble act that could inspire change in the ninja world. They might start to advocate for more cooperation between villages. His friends from the academy days would be devastated. They would remember all the good times with Naruto and how he always tried to make them laugh. This could lead to some of them trying to follow in Naruto's footsteps and work towards a more harmonious ninja world, even in the face of his tragic death.
Sasuke would be deeply affected. He and Naruto had a complex relationship. He might feel regret for not being there to help Naruto and also feel a new sense of purpose in avenging his friend. Sakura would be heartbroken. She had always cared for Naruto, and his death would make her question the purpose of the ninja life. Haku herself would be in a state of shock and disbelief. She would feel a heavy burden of guilt, knowing that Naruto sacrificed his life for her. She might become more withdrawn initially but then use Naruto's memory as a motivation to become stronger.
Sasuke would be deeply affected. He and Naruto had a complex relationship. His first reaction might be shock and then a deep sense of loss. He might feel guilty for not being there to help Naruto. Sakura would be heartbroken. She had always cared for Naruto, and his death would be a huge blow. She might become more determined to protect the village in his memory. And Boruto, Naruto's son, would be devastated. He would probably grow up with a strong sense of purpose to live up to his father's sacrifice and protect the village even better.
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.
It would be a huge shock. Naruto is seen as a hero in the ninja world. His death protecting Fem Haku would make the other villages re - evaluate their relationships with Konoha. Some might see it as a noble sacrifice and offer support, while others might see it as a weakness. And the Akatsuki might take advantage of the situation to cause more chaos.
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.
One possible plot could be that Naruto is somehow transported to the Bleach universe. He meets Haku there, and they form a bond. When Haku is in danger from some powerful Bleach - related threats like Hollows or powerful Soul Reapers who misjudge Haku, Naruto steps in to protect him. In the process, Naruto, with his ninja skills but lacking the full understanding of the Bleach world's powers, gets overwhelmed and dies while trying to shield Haku.
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.
Sakura would likely be devastated. Naruto has been her friend and teammate for a long time. His death would leave a huge void in her life, and she'd probably go through a long period of mourning.
The characters in 'Naruto' would be deeply affected if Naruto dies at birth in fanfiction. Jiraiya would be one of the most affected. He saw Naruto as his protege and the hope for the future. Without Naruto, Jiraiya might lose his enthusiasm for training and spreading his teachings. Tsunade would also be saddened as she had a connection to Naruto through her relationship with Jiraiya and Minato. The Rookie 9, Naruto's friends, would have a completely different dynamic. They might not form as tight a group without Naruto's energetic and positive influence. And the Sannin, as a whole, would have their relationships and legacies altered without Naruto in the picture.
Naruto might also try to remember Sakura in a positive way. He would cherish the memories they had together. He could start initiatives in the village in her name, like promoting medical ninja training more, since Sakura was a great medical ninja. He would slowly turn his grief into a force for good in the village.
Well, one possibility could be that Naruto sacrifices himself to save Fem Haku from a powerful enemy. Maybe it's during a battle against a new and dangerous foe that has emerged in the Naruto universe. His death would likely have a huge impact on the other characters, especially those close to him like Sasuke and Sakura. They might be filled with grief and a strong desire for revenge.
