I have no idea as I haven't read the novel. It could be a patient with heart trouble as the main character.
Not having read it, it might have a cardiologist as one of the main characters. He or she could be deeply involved in treating patients with heart trouble, and through this character, we could learn about the medical aspects as well as the human side of dealing with heart problems. There could also be a patient's family member as a main character, who has to support the patient and deal with their own emotions.
Often, there will be a central girl character who is facing the trouble. She could be a teenager, like a high - school girl dealing with bullying or family issues. There might also be her best friend who plays a supporting role, either helping her out or getting into trouble alongside her.

There could be a diverse range of characters. It might have a young, naive character who gets dragged into the big trouble and has to grow up quickly.

And of course, there could be side characters like friends or family members of the main character who are also affected by the big trouble.
I don't have enough information to say exactly who the main characters are. They could be astronauts, space pirates, or scientists, depending on the story of the visual novel.
I don't know as I'm not familiar with this novel. But typically, main characters in a novel about the troubles of being born might include the newborn or those closely related to the newborn, like the parents or siblings.
Since I haven't played it, I don't know the exact main characters. But usually in a visual novel, there are characters that drive the story forward. They could be people with different personalities, like a brave protagonist, a mysterious side - character, or a wise old mentor - like figure.
It's possible that there is a lone detective - like character. This person is drawn to the mystery and trouble that is scaring people. They are brave and determined to solve the mystery behind the scary events, and in the process, they become the main focus of the story as they face the various horrors.
I'm not sure exactly as I haven't read it. But usually in such novels, there could be a protagonist who drives the story forward. Maybe it's a young person on a journey of some kind.
I'm not sure specifically without reading the 'the heart novel'. But usually, there's a protagonist who drives the story forward. There might also be a love interest, a mentor figure, and an antagonist who creates conflict.
