Without having read the 'heart stone novel', I can only guess. There may be a character who stumbles upon the heart stone by accident and then becomes the central figure in the story. There could be an old wise character who knows about the heart stone's history and tries to guide the younger characters. And perhaps there are some antagonists who will stop at nothing to get their hands on the heart stone for power or wealth.
Since it's a novel, it's likely to have a complex set of characters. There might be a group of people who are on a journey with the main character. Some might be allies, trying to support the character in changing their stone cold heart. Others could be rivals within the group, creating internal conflict while the main character is also dealing with their own emotional state.
I don't know for sure. It could be a hero with a mysterious past.
Since it's a graphic novel, there might be a group of adventurers as the main characters. One could be a strong and silent warrior type, who is physically capable of protecting the stone heart. Another could be a clever thief who has the skills to steal or retrieve the stone heart from dangerous places. And there could be a wise scholar among them, who can decipher the ancient texts and clues related to the stone heart's origin and power.
Most likely the main characters are the Beauty and the Beast. Just like in the traditional story.
It's hard to say without more details, but there could be a fearless warrior as one of the main characters. This warrior might be on a mission related to the heart of stone.

The main characters include Arthur, who is the hero of the story. He is naive at first but grows into a great leader. Merlin, the magician, is a very important character. He has knowledge of the future and uses his powers to shape Arthur's journey. Additionally, there are various knights and lords who interact with Arthur as he rises to power, such as Sir Kay, Arthur's foster brother.
I'm not entirely sure without more research, but usually there is a central female character who is often the focus of the self - discovery journey in such novels.
I'm not sure exactly as I haven't read the novel. But typically, there would be a central character, perhaps the owner of the house or someone with a deep connection to it. Maybe it's an older character who has a lot of stories to tell about the house.
