His relationship with Sasuke would likely be affected. With the new powers from the Light - Light Fruit, Naruto might be seen as a greater threat by Sasuke, or Sasuke could be intrigued and want to learn more about the fruit's powers. Naruto's friends in Konoha would also view him differently. They would be both amazed and a little bit cautious as his powers would be very different from what they're used to.
Naruto was a Japanese manga and animation, not a light novel. It originated from the work of the Japanese manga artist Kishimoto, Naruto, and was widely spread in Japan and overseas. Naruto had a rich storyline and many loyal fans.
Well, Naruto's chakra control would have to adapt. In the Dying Light world, he might use his chakra to enhance his weapons, like making a kunai cut through the tough zombie hides more easily. His Rasengan could also be modified. Instead of just being a powerful close - range attack, he could potentially throw it like a grenade in the Dying Light environment, causing a lot of damage to groups of zombies. And his sensing ability, which he uses to detect enemies in his own world, could be used to sense the approaching zombie hordes from a distance.
Another place to check is Naruto - focused forums. Often, members of these forums write and share their own fanfictions. They might also recommend good ones that they've read. Some popular Naruto forums could be a great source for finding quality light novel fanfictions.
One creative plot twist could be Naruto somehow obtaining the Light - Light Fruit powers. This would completely change his combat style. Instead of relying on his chakra - based jutsus, he could use light - based attacks like creating blinding flashes to disorient opponents or using concentrated light beams as a weapon. Another twist might be that the Light - Light Fruit has a connection to the Sage of Six Paths' power, revealing a hidden aspect of the Naruto universe's power structure.
In a Naruto Dying Light fanfiction, a cool plot could be that Naruto's chakra has an unexpected effect on the virus in the Dying Light world. Maybe his positive chakra energy starts to slowly purify the infected areas. Also, there could be a story where Naruto has to face off against a powerful zombie - like enemy that has some of the abilities of the ninja he's faced in his own world, like being able to use genjutsu - like illusions on the survivors.
Well, in a Naruto and Dying Light fanfiction, there are so many possibilities. Naruto's chakra could be a unique element in the Dying Light world. He could use it to power up makeshift weapons or to heal the injured survivors. Also, the idea of Naruto facing off against the powerful volatiles in Dying Light is exciting. His shadow clone jutsu could be used to distract the zombies while he makes a strategic move. And his positive attitude would surely boost the morale of the survivors in that dark and dangerous world.
