The main character is probably the half - prince. There may also be characters like his friends or mentors who play important roles. For example, a wise old wizard could be a key figure guiding the half - prince through his journey, or a brave knight - in - training who is his loyal friend and ally.
Since it's a 'half prince light novel', the titular half - prince is surely a main character. There could be other significant characters such as his family members. Maybe he has a conflicted relationship with his royal parent or his non - royal side of the family. Additionally, there might be antagonists, like power - hungry nobles or dark mages who oppose the half - prince and create obstacles for him in his path. These characters together would drive the story forward through their interactions and the resulting conflicts.
The Half - Blood Prince himself, though his identity might be more of a mystery or a key to be uncovered in the fanfiction. His influence through his notes and spells would be a major part of the story.
The 'Half - Blood Prince' is Severus Snape. He was a half - blood wizard, son of a Muggle father and a witch mother. His old potions book that Harry uses is filled with his own spells and notes, which is how Harry discovers his identity as the 'Half - Blood Prince' later in the story.
Well, the half - elves themselves are surely main characters. There might be a male half - elf who is brave and kind, with his elven grace and human tenacity. And a female half - elf who is perhaps intelligent and beautiful, with a unique charm that comes from her mixed heritage.
The main characters are Harry and Ginny. Harry is the central figure in the wizarding world's fight against Voldemort. Ginny, on the other hand, is not only important as Harry's love interest but also has her own strength and character. Sometimes, characters like Dumbledore or Snape might also play important roles in the fanfiction as they are closely related to the events in the Half - Blood Prince.
There are also the captors. They play important roles as they are the ones who hold the power over the prince at the start. Their motives and actions drive much of the conflict in the story.
The main character is the Genius Prince. He is surrounded by a cast of characters. His closest confidants, like his chief advisor who has been with him since his childhood, are important. There are also antagonists in the form of power - hungry lords within his own kingdom who oppose his progressive ideas. Additionally, characters from foreign kingdoms, such as envoys and spies, add to the complexity of the story as they interact with the Genius Prince in various ways, either as allies or foes depending on the situation.
Since I haven't read the 'Prince of Genius' light novel, it's hard to name the main characters precisely. However, we can assume that there is the titular 'prince of genius' character. There could also be antagonists, like rivals who are jealous of the 'prince of genius' intelligence or power - hungry individuals who see the 'prince of genius' as a threat. And perhaps there are family members who play important roles in the story, either supporting or creating obstacles for the main character.
I'm not entirely sure who all the main characters are, but it's likely there are some young male characters who are really into stride. They might be the leaders or the most talented members of their stride teams.
The main character is the genius prince himself. There are likely to be his advisers and generals who play important roles as well, helping him in his quests and decision - making.
Obviously, Harry is one of the main characters. He's the one who has the Half - Blood Prince's book. Hermione might also be a main character as she often helps Harry understand the complex knowledge in the book. Ron could be there too, providing his unique perspective and support.
