Since we only have the title to go by, it's difficult to determine the exact main characters. However, aside from the princess, there could be a villain who is trying to undermine her. There may also be a mentor - like figure who helps the princess maintain her facade and deal with the underlying issues. Maybe there's a best friend or confidant who is privy to some of the princess's secrets.
Given the title, the princess is surely a central character. There could be courtiers or noblemen and women who interact with her, and their relationships could be complex. For instance, some might be envious of her position and try to bring her down. There could also be a character who is in love with the princess but is unaware of her true situation beneath the facade, adding another layer of drama to the story.
Since I don't have access to the novel, it's hard to say exactly. But generally, in stories like this, the 'beneath' part often implies that there are hidden aspects to the princess's character or situation. Maybe she's facing threats to her throne, or has a tragic past that she's hiding behind her joyous appearance.
The main character is surely the barbarian. But there could also be a mentor figure, an older and wiser barbarian who guides the main character. Maybe there's a love interest, a female character from another tribe or group. And of course, there would be villains, like the leaders of enemy tribes or some sort of evil sorcerer.
There could also be antagonists in the story. These characters would oppose the protagonist and create conflict. They might represent the forces of oppression or the chaos that the protagonist is trying to overcome, whether it's an individual or a group within the setting of the novel.
Since I haven't read it, I can't say for sure. But typically, there could be a brave adventurer, a wise old mentor - like figure, and maybe some unique ice - adapted creatures as main characters.
Well, the main character is surely the barbarian. He or she is likely to be joined by comrades, perhaps other barbarians or characters from different races who share the same goal of survival. There could be an antagonist as well, maybe a powerful wizard or a cunning thief who tries to undermine the barbarian's efforts. And there might be a love interest, a female character who gives the barbarian an extra motivation to survive.
I'm not entirely sure who the main characters are specifically without having read it in full. But usually in a graphic novel about surviving the city, there could be a young protagonist, perhaps a teenager, who is facing the challenges of the city head - on.
I'm not sure specifically as I haven't read this exact novel, but typically in a high school - themed novel, there would be a protagonist who is likely a student. There may also be a best friend character, a popular kid who might be a rival or an idol, and a teacher who has an impact on the main character's high school journey.
I'm not entirely sure without more research, but they were probably soldiers involved in the events at Hill 60.
Then there's a wise old wizard called Merlin. He guides Alex with his vast knowledge and magic skills. There is also a female character, Lily, who is strong - willed and has her own special abilities. She often comes up with creative solutions when they are in trouble.
The main character is, of course, the barbarian. But there may also be other important characters like the game masters who control the flow of the game, or other players who the barbarian interacts with. Maybe there's a mentor - like figure who gives the barbarian advice on how to survive and thrive in the game.
