A new character could be introduced as the main character. Maybe a transfer student from a different magical school who has unique skills related to wards. This character could bring a fresh perspective to the Hogwarts wards and interact with the existing characters in interesting ways.
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.
Hermione Granger would also make a great main character. Her intelligence and love for knowledge would be perfect for exploring the complex magic behind the school wards. She could spend hours in the library researching about the wards' origin and how to improve them.
Harry Potter himself could be a main character, as he has a deep connection to Hogwarts and would surely be involved if the wards were in trouble. Hermione would also be a great choice, with her vast knowledge of magic, she could be crucial in understanding and repairing the wards. Ron could be there for support and his own brand of bravery.
Harry Potter himself is often a main character. Since the blood wards are related to his protection at Hogwarts, his actions and experiences are central. Hermione Granger might also be a key character as she is always involved in solving magical mysteries and could be trying to understand the blood wards better. Ron Weasley too could be there, as he is Harry's best friend and often gets involved in any Hogwarts - related adventures.
Obviously, Harry is one of the main characters. And the wards he is raising would also be main characters. But without reading it, we can't be sure who these wards are specifically.
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.
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.
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 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.
Well, he might discover some hidden secrets while cleaning. Maybe he stumbles upon a long - forgotten spell or a mysterious object that has been lost for ages.
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.
