If Naruto got the Death Note, it would be a complete chaos. Naruto has a strong sense of justice, but his understanding of it is very different from Light's in Death Note. He might initially be horrified by the power of the Death Note and try to destroy it. However, if he decided to use it, he could potentially target powerful enemies like Orochimaru or Pain without having to engage in direct combat. But this would also corrupt his ninja way as killing without a fair fight goes against his beliefs. He would likely struggle with the moral implications throughout the story.
Naruto would first be extremely confused by the rules of the Death Note. His understanding of power and its consequences is rooted in his ninja training and his own moral compass. The Death Note's rules, which seem so simple yet so deadly, would be completely foreign to him. He would question why anyone would create such a thing and would be very hesitant to even consider using it, as it goes against everything he stands for in his world of ninjas, friendship, and protecting the innocent.
Yes, there are likely to be such fanfictions. The 'Harry Potter' and 'Death Note' universes are both very popular, and fans often like to combine different fictional worlds in fanfiction. They might create stories where Harry Potter gets his hands on a Death Note and all kinds of interesting and unexpected scenarios unfold as a result.
One great 'Naruto and Death Note' fanfiction is 'The Shinobi's Death Note'. It combines the unique power systems of both universes really well. The story has Naruto stumbling upon the Death Note and trying to figure out how to use it in a way that aligns with his ninja values.
The shinobi world's reaction would be complex. At first, there would be disbelief. Many would think it's some kind of new genjutsu or a hoax. But once they realize it's real, the more superstitious ninja would see it as a curse from the gods. The Hidden Sand Village might see it as a potential weapon against their enemies, while the Hidden Mist Village might be more cautious due to their history of bloodshed. The shinobi academies would start teaching about the Death Note as a new and dangerous threat. There would also be a black market for Death Note information, with some trying to sell false ways to protect against it.
Well, Naruto's ninja skills and his strong sense of justice would likely clash with the concept of the Death Note. He might try to stop the use of the Death Note as it goes against his moral code of not taking lives unjustly.
If Naruto had the Death Note in fanfiction, it would be a total game - changer. He might struggle with the moral implications at first. Naruto is all about saving people and making friends, but if he saw how powerful the Death Note was in eliminating real threats to his village, like the Akatsuki members one by one, he might be tempted to use it. However, this would also put him at odds with his ninja way to some extent.
An immortal Naruto in a Death Note fanfiction would probably start by trying to understand how the Death Note works. Since he doesn't have to worry about dying, he could get his hands on the Death Note and experiment. He might also try to protect the innocent people who are being targeted by the Death Note users. He could use his ninja skills like stealth and combat to take on the bad guys in this new and dangerous world.
If Naruto found a Death Note fanfiction, he'd probably be really confused at first. He comes from a world of ninjas and chakra, and the concept of the Death Note is so different. He might try to understand how this strange 'book' in the story works, with its rules about writing names to cause death. But in the end, he'd probably just shrug it off as a really odd and dark story from another world's imagination.
His view on life and death would be challenged. In Naruto's world, he fights to protect life, but the Death Note's power to kill so easily might make him more cautious and serious about the value of life.
