The main characters are quite distinct. Anna, she's at the center of the story as she begins to fight against the role she was seemingly born for. Kate, the sick sister, her condition is what sets the whole plot in motion. The parents are key too. The mother is so focused on Kate's survival that she sometimes overlooks Anna's feelings. The father, on the other hand, is caught in the middle, trying to balance the needs of both daughters and deal with his own feelings about the situation. Their interactions and individual personalities make up the heart of the'my sister's keeper novel'.

Since we don't have a clear idea of 'the keeper graphic novel' without reading it, the main characters could include the keeper, of course. There might be a character from a different culture or species that the keeper has to interact with. This character could bring new perspectives and challenges to the keeper. There could also be a character representing the power or force that the keeper is up against, whether it's a dark magic user or a powerful corporation in a dystopian setting.
I don't really know, but I assume there's the dragon keeper for sure. And of course, the dragon itself.
I'm not sure exactly who the main characters are without having read the novel. But usually, there would be a protagonist who drives the story forward and perhaps some supporting characters that interact with the protagonist in important ways.
