I recommend the book,"Please Don't Be Dark, Big Boss." Although the plot of this book was a little complicated, there was a story in which the female protagonist was a beauty blogger, and there was some ambiguity between the male and female protagonists. I hope you like this fairy's recommendation. Muah ~😗
One interesting concept could be an exploration of Naruto's dark side. It might show how his experiences could have turned him truly evil, like if he had been more influenced by the hatred in the ninja world from the start. Maybe in this fanfiction, he uses his powers for self - gain rather than for the good of the village.
There are various reasons. Maybe an evil artifact influences her, or she's deceived by a villain with persuasive powers. These storylines add depth and complexity to her character.
One possibility is that Naruto's transformation into a robot could change his relationships. His friends might be initially shocked and have to learn to trust this new robotic version of him. He could also face new enemies who are specifically targeting him because of his unique robotic - ninja nature. His sensei might have to train him in different ways to make use of his robotic abilities, like teaching him how to maintain and upgrade his robotic parts.
It could lead to a whole new dynamic in the story. Maybe Naruto's relationships with other characters would change, and her ninja skills might be perceived differently.
I think he could be turned into a Pikachu. Pikachu is known for its spunk and determination, which are traits Naruto also has. Plus, both are quite small but extremely powerful in their own ways. Naruto's energy could be translated into Pikachu's electric powers in an interesting way.
One common theme could be revenge. If Naruto is portrayed as evil, it's likely he's seeking revenge for past wrongs. Another theme might be power corruption. He has a lot of power, and in these fanfics, it could corrupt him. Also, a sense of disillusionment with the ninja world and its values could be a theme.
The Ancient Spirits of Evil in Naruto fanfiction could be tied to ancient jutsu or forbidden arts. Perhaps they were once experimented on by long - dead ninja clans, and now their presence is being felt again. They might have the ability to corrupt the minds of those they come into contact with, turning even good - hearted ninja to do their bidding.
I'm not sure specifically as there could be many different takes on it. But generally, it might involve Naruto having an 'evil' side while also being involved in gaming - like using gaming - like skills or concepts in his ninja world. Maybe he uses game - like leveling up to gain power in a more devious way than in the original story.
