The main characters in 'the ring graphic novel' could be diverse. There might be a young protagonist who is initially unaware of the ring's true nature but gradually discovers its power and the danger it poses. There could also be an old sage - like figure who has some knowledge about the ring's history and tries to guide the protagonist. And, of course, there would likely be some sort of dark entity associated with the ring that serves as a constant threat to the other characters.
I'm not entirely sure, but there might be a character who discovers the ring. Maybe a curious explorer or an unlucky person who stumbles upon it.
Often in such graphic novels, there could be a hero - like a brave person who tries to fight against the evil of the ring. And then there could be antagonists who are attracted to the power of the ring and want to use it for bad purposes. It could also have some side characters like friends or family of the main character who get involved in the story one way or another.
Siegfried is likely one of the main characters. He is a heroic figure often associated with great strength and courage in the Ring of the Nibelung story.
I'm not entirely sure who the main characters are specifically in the 'Elden Ring Graphic Novel' as it might be based on the game where there are many key characters such as the Tarnished. The Tarnished are the ones on a journey to restore the Elden Ring, so they could be main characters in the graphic novel too.
The main characters include Frodo, who is on the central quest to destroy the ring. Samwise Gamgee, his loyal friend and gardener, is always by his side. There's also Gandalf the wizard, who guides and protects the fellowship. Aragorn, Legolas, and Gimli, as I mentioned before, are key members. And Merry and Pippin, the other hobbits, who also play significant roles in the story of the 'Fellowship of the Ring Graphic Novel' through their own actions and adventures.
There's Alberich, the Nibelung dwarf who creates the ring. Also, Wotan, the god who has a great interest in the ring.
There's no way to be certain without reading it, but perhaps there's a female lead who is somehow connected to the ring. Maybe she has a special ability that is awakened by the ring, and there could be a male character who helps her on her journey with the ring. There could also be an antagonist who wants to steal the ring for their own malicious purposes.
I'm not sure specifically as there are many novels that could be called 'the ring novel'. But generally, there could be a protagonist who discovers the ring and gets caught up in its mystery. There might also be an antagonist who wants to use the ring's power for their own evil purposes.
Sadako Yamamura is a main character. She is the source of the curse, a figure full of mystery and horror.
As I'm not familiar with the 'the broken ring novel', I can only speculate. There could be a protagonist who is on a quest related to the broken ring. This could be a young person full of curiosity, trying to figure out the story behind the broken ring. There might be an antagonist as well, perhaps someone who wants to keep the secrets of the broken ring hidden. And there could be a supporting character, like an old jeweler who provides some valuable information about the ring's origin and possible ways to fix it.
Since I don't know the exact 'the magic ring novel', I can't say for sure. But usually, there would be a protagonist who discovers the ring.
As of now, there is no official 'Elden Ring' novel, so it's hard to say who the main characters would be. But if it followed the game, Tarnished could be a main character as they are central to the game's story.
