Well, Naruto has a rich and detailed world. In high school fanfiction, this world can be easily adapted. For example, the ninja skills can be turned into unique abilities in a high school context. And the pre - existing relationships in Naruto can be tweaked to create interesting high school dramas, which makes it popular.
Sasuke could also be very popular. His cool and mysterious aura would attract a lot of attention. Girls might be drawn to his brooding nature and his exceptional skills. However, he might not be as approachable as Naruto. He'd be the loner that everyone wants to be friends with but is too intimidated to approach. Then there's Hinata. Her shy and kind nature would make her popular among the more sensitive students. She'd be the girl that many would want to protect.
It could be really awkward. Hinata would be so shy that she might not even be able to look at Naruto directly. Naruto would probably be too busy chatting with his friends and not really notice Hinata at first. But then maybe Naruto accidentally bumps into Hinata in the hallway, and he quickly apologizes. Hinata would just mumble a response while blushing furiously.
In high school in this fanfic, Naruto would likely be known for his pranks. Hinata, on the other hand, would be the quiet and studious one. Their relationship could start with small exchanges, like Naruto borrowing a pencil from Hinata in class. He might not think much of it at first, but Hinata would be so nervous. As time goes on, Naruto might start to see Hinata in a different light, especially when she stands up for him against some bullies. This could be the start of a sweet high school romance.
One great fem Naruto high school fanfic is 'Fem Naruto's High School Adventure'. It has an interesting plot where Fem Naruto has to deal with typical high school drama while also hiding her ninja skills. The character development is really well - done.
He could be a new type of threat or ally in the DxD world. Since Naruto has such powerful abilities, the fallen angels might see him as a potential weapon or a hindrance to their plans.
One idea could be to create a fanfic where Naruto is somehow transported to the world of High School DxD. He could bring his unique ninja skills and chakra system. Maybe he teams up with Issei to fight against a common enemy. For example, a powerful devil or fallen angel that threatens both the ninja world and the DxD universe.
At first, it might be just small exchanges. For example, Naruto might say hello to Hinata in the hallway more often. Then, they could be assigned to the same team for a sports event. Hinata's support for Naruto during the event makes him see her in a different light. He starts to seek her out more, and they gradually become friends. As friends, they learn more about each other's dreams and fears. This deepens their bond, and slowly, romantic feelings start to develop between them.
Naruto is definitely one of the most popular characters. His energetic and determined personality makes him a central figure in many fanfictions set in Konoha High School. He's often the one getting into trouble and then finding solutions.
In addition to the main trio, Kakashi can be a popular character in these fanfictions. As a teacher at the ninja high school, he can offer wisdom and guidance to the students. His laid - back yet highly skilled nature adds an interesting dynamic. Another character could be Rock Lee. His unwavering dedication to being a ninja through hard work, despite not having natural talent like some others, can be an inspiring and popular element in the fanfictions.
