There could be a wizard named Oliver who is from a long line of powerful Salem School alumni. He is very popular but also has a secret ambition to bridge the gap between Salem School and other wizarding schools like Hogwarts.
A young witch named Lily who is new to Salem School and is trying to find her place among the different cliques. She has a natural talent for potion - making but struggles with charms.
There could be a young Salem witch named Lily. She befriends Fem Harry Potter and shows her around Salem. Lily could be very knowledgeable about the local magic and help Fem Harry Potter understand the differences between Hogwarts magic and Salem magic.
There could be an older, wise ghoul teacher who serves as a mentor to the students. This character could have a lot of knowledge about the school's history and the ways of the magical world of ghouls.
The main characters could include a group of neko students. There could be a fearless leader named Kitty, who is always ready to stand up for her fellow nekos. Then there's a shy neko named Whiskers, who has amazing magical powers but is too timid to show them. And there could be a human teacher at the neko school, Professor Brown, who has to learn about neko culture while teaching them magic. These characters could go through various adventures together, like exploring a hidden part of the school or facing a powerful dark wizard who wants to use the nekos' powers for evil.
Obviously, Harry Potter himself could be a main character. He has so much experience with the school and its magic. He could be the one to discover a new aspect of the school wards and lead the effort to protect or repair them.
Obviously, Harry could still be a main character. He'd be the brave new kid in high school, trying to make friends and figure out his place. Hermione would also be there, the super - smart girl who is always acing her classes and getting involved in every club. Ron could be Harry's best friend, the laid - back but loyal guy. And Draco could be the rich, snobby kid from the 'popular' group who constantly gives Harry a hard time.
There could be a group of Japanese students who are initially skeptical of Harry but later become his allies. For example, a shy girl who is really good at Japanese magic but lacks confidence. And a tough - looking boy who is actually very kind-hearted and they all form a sort of magical study group together with Harry. There might also be a mischievous Japanese magical creature that befriends Harry and causes some chaos in the school.
Obviously, Harry is one of the main characters. There could also be some original characters created specifically for the Salem setting, like a local witch who befriends Harry. And sometimes Hermione or Ron might make an appearance, especially if the story involves some sort of connection between Hogwarts and Salem.
Well, he might encounter different kinds of magic there. Salem has its own history of witchcraft. Maybe he'll meet new witches and wizards who practice magic in a different way from what he's used to at Hogwarts. He could also discover new magical creatures or spells specific to the Salem area.
Often in fanfiction like this, Hermione would also be a prominent character. She might be intrigued by the Kitsune magic and study it intensively. Maybe she tries to find books in the library about Kitsune to understand how their magic works compared to wizard magic. Ron could also be there, perhaps being a bit skeptical at first about these new magical beings in their school.
For a Harry Potter battle school fanfic, the main characters could include some of the more under - rated students at Hogwarts. For example, Seamus Finnigan, who has shown his magical abilities in the past but could really shine in a battle school setting. Ginny Weasley, being a strong - willed and talented witch, could be a main character as well. Additionally, Draco Malfoy could be a complex main character, as he could either be a rival in the battle school or, over time, learn to work with the others against a common enemy.
