I don't have information on this graphic novel's characters. It could be a hero who is trying to overcome his or her original sin, or it might have a group of characters each with their own connection to the concept of original sin.
Since I haven't read the 'original sin graphic novel', it's hard to say for sure. However, it's possible that there could be a protagonist who discovers their original sin and is on a journey to understand and deal with it. There might also be some antagonist characters who either represent the forces that encourage the indulgence in the original sin or are trying to prevent the main character from dealing with it in a positive way. Maybe there are also some side characters that serve as the moral compass or the ones who have already come to terms with their own original sins and can offer guidance.
Without having read the 'original sin graphic novel', it's difficult to name the exact main characters. But typically in a story about original sin, you might expect a central character who is grappling with this fundamental flaw within themselves. This character could be a young person just coming to terms with their identity and realizing that there is something deep - seated that they need to address. There could also be an older, wiser character who has some knowledge about the nature of original sin and tries to help the main character. And perhaps there is a character who embodies the allure of the original sin, tempting the protagonist to give in to it.
