It could be a student who discovers the presence of the devil in the school. This student would then be at the center of the story, trying to figure out how to deal with this supernatural threat and protect the school and its students.
Perhaps a teacher. A teacher might be the main character if they have some sort of special knowledge or ability to sense the devil's presence. They could be the one to lead the fight against the devil, while also trying to educate their students and maintain order in the school.
Naruto himself could be the main character with a devil bloodline twist. Maybe he was born with it but it was hidden until a certain event triggered it. This would completely change his journey. Instead of just trying to gain the respect of the village as a Jinchuriki, he would also have to deal with the implications of having a devil bloodline, which might be seen as even more dangerous by some in the village.
I don't know for sure since I haven't read the novel. But I would expect there to be the devil character as a main one. There might also be some students, teachers or other people in the school environment who interact with the devil.
The main character could be a small spider. It's trying to find a place to build its web in the school and has all kinds of adventures while doing so.
A curious journalist. They are always looking for a good story and an abandoned school is full of potential.
The main character could be a student athlete. He is constantly under pressure from the coach who is 'ballbusting' him to improve his performance. The athlete has to balance his studies, his social life, and the intense training regime.
The main character could be a popular girl in school who becomes a giantess overnight. This completely changes her social status. Some of her so - called friends turn their backs on her, but she makes new ones among the outcasts. She uses her new size to stand up to the school bullies and in the process, she transforms the school into a more inclusive and accepting place.
It might be a brave girl who stands up against the wedgie - giving culture in the school. She's not afraid to speak out against the bullies who use wedgies as a form of harassment. She forms a group of like - minded students, and together they create a safe space in the school where no one has to fear getting a wedgie. Her leadership and determination make her the perfect main character for this type of story.
It could be a new student at Hogwarts who has the powers of a Lightning Devil Slayer. This character would be an outcast at first, not fitting in with the normal wizarding students. But as the story progresses, they use their unique abilities to save the day, for example, during a battle against a horde of Dementors where their lightning - based powers are especially effective.
The main character, the boy, could be someone with a very unique personality. Maybe he's a bit of a rebel and doesn't really care about the fact that he's in an all - girls school. He could be confident and use this opportunity to make a name for himself. Or he could be a shy boy who is really intimidated at first by all the girls around him.
