Sometimes, it's an existing Naruto character who is given the Light Release bloodline in an alternate universe story. For example, Naruto himself could be given this bloodline, which would change his fighting style completely. He could use his natural exuberance and combine it with the light powers to create some really unique and powerful jutsu.
Another possibility is that a member of a minor clan in the Naruto world is the main character. They might have been overshadowed by more well - known clans, but with the discovery of their Light Release bloodline, they rise to prominence and play a crucial role in the story, whether it's in battles against the Akatsuki or in protecting their village.
Naruto himself is often a central character. Since he has his own unique chakra nature and potential, fanfictions might explore how his own abilities interact with different bloodlines. Sasuke is also common, given his Sharingan bloodline. Hinata could be involved as her Byakugan bloodline is quite interesting. And sometimes, new or original characters created specifically for the fanfiction might also be main characters, especially if they possess some sort of rare or infamous bloodline.
Naruto himself is obviously a main character in most of these fanfictions. Since it's about the Namikaze bloodline and he's the son of Minato Namikaze.
Often, Naruto himself might be involved as he is the main character of the original series. He could be the one to discover or master a new particle release. Sasuke could also be a main character in such fanfiction, perhaps using his Sharingan in combination with particle release in unique ways.
There might be a mentor figure, an older ninja who has some knowledge about the crystal release bloodline, even if they don't possess it themselves. They guide the young character in understanding and using their powers. For example, they might teach the protagonist how to shape the crystals into different forms like weapons or shields. Another common character could be an antagonist who covets the power of the crystal release bloodline and tries to either steal it from the protagonist or prevent them from fully realizing its potential.
Sasuke is often involved. Given his natural inclination towards power and his Sharingan, it's easy to imagine him exploring the Meiton Release. His quest for power could lead him to discover and master this dark release. Another one is Naruto himself. Fans might write about Naruto learning Meiton Release to add a new dimension to his already vast arsenal of jutsu, perhaps as a way to face an even stronger enemy.
Naruto himself is often a central character in 'naruto destruction fanfiction'.

Well, Naruto is obviously a main character in most of these. But there could also be Sasuke. He might be either an ally or an adversary in relation to the dagger. For example, if the dagger has a power that can either be used for good or evil, Sasuke could be tempted by its darker potential.
Some fanfictions might also include characters like Kakashi in important roles. As Naruto's former teacher, he could be a guiding figure or someone who has to adapt to Naruto's new level of power. He might also be involved in trying to keep Naruto's power in check if it starts to have negative effects on the ninja world.
