Since I don't have in - depth knowledge of the Charlotte Visual Novel, it's hard to name the exact main characters. However, in most visual novels, there is often a central character around whom the story revolves. There may also be supporting characters like friends, family members, or rivals who play important roles in the development of the story.
Charlotte is one of the main characters, of course. Her character is central to the story.
Yuu Otosaka is one of the main characters. He has a special ability.
The main character is Yuu Otosaka. He has the power to possess others briefly. There's also Nao Tomori, a girl who is part of the organization dealing with those who have special abilities. Ayumi Otosaka is Yuu's sister.
Obviously, Queen Charlotte is a central character in the 'Queen Charlotte' novel. Her husband would be an important figure as well, as their relationship would have a great impact on the story. Courtiers, who were part of the royal court, would also be significant. They might be friends, foes or advisors to Queen Charlotte. Servants could also be main characters in a way, as they would provide a different perspective on the goings - on in the palace and their interactions with Queen Charlotte could reveal aspects of her character.
Charlotte is likely one of the main characters. She's probably at the center of all the stories.
The main characters are Wilbur, the pig, and Charlotte, the spider.
There could also be her friends. For example, a best friend who always taste - tests her new smoothie creations and gives her honest feedback. This friend might be really important in helping Charlotte improve her smoothies.
Obviously, Charlotte and the monster are the main characters.
Queen Charlotte herself is likely to be a main character. There might also be fictional characters created for the story, like a young servant who has a special connection with the Queen.
Since we only have the name 'charlotte monster story', we can assume that Charlotte is likely one of the main characters. And of course, there's the monster. But there could be other characters too, like Charlotte's friends or family members who might be involved in the story, perhaps trying to protect Charlotte from the monster or helping her deal with the situation the monster brings.
