In addition to Naruto, there might be some side characters from the Naruto universe who take on different roles in this fanfiction. For instance, Kakashi could be an advisor to Naruto in his new position. And there could be original characters created specifically for this fanfiction, such as a strange being that exists only in the pandemonium realm and has a special relationship with Naruto, either as an ally or an enemy.
It could also introduce new characters. Maybe there are powerful demons or spirits that Naruto has to deal with. These could be main characters in the sense that they drive the conflict. For example, a powerful demon who wants to overthrow Naruto's rule over the pandemonium realm.
Well, it could be about Naruto in a role where he has some sort of lordship over a pandemonium - perhaps a chaotic realm. Maybe he has to deal with all kinds of unruly forces and characters within that setting.
Without having read the 'pandemonium novel', it's impossible to accurately name the main characters. But they might include a hero - type figure who tries to bring order to the pandemonium. There could also be a villain who thrives on the chaos and tries to prevent any restoration of order. And perhaps there are side characters like a wise old mentor who gives advice to the hero on how to deal with the pandemonium, or a love interest who provides emotional support to the main character throughout their journey in the chaotic world of the novel.
I'm not sure as I haven't read it specifically. But typically in a visual novel, the main characters could include a protagonist who drives the story forward, perhaps a love interest, and some antagonist characters who create the conflict.
Since I'm not familiar with the 'pandemonium graphic novel', the main characters could be designed to fit the theme of pandemonium. There might be a character who is the cause of the chaos, and others who are trying to stop it. There could also be characters who are just trying to adapt to the chaotic situation. For instance, a young protagonist who discovers the source of the pandemonium and decides to take action against it.
In many graphic novels, there are often a diverse set of main characters. In 'pandemonium 2 graphic novel', there could be a strong - willed leader type who is trying to navigate through the chaos. There might also be a sidekick or a supporting character who provides comic relief or different perspectives. There could be an antagonist as well, someone who is causing the pandemonium or trying to stop the protagonist from achieving their goals.
I don't know for sure as I haven't read it. But usually in a series, the main characters from the first book might continue to be important in the second. So, there could be a heroic lead character, perhaps with some special abilities or a strong will.
There might be a hero or heroine who is trying to make sense of the pandemonium in the story. There could also be some antagonists who are causing or adding to the chaos. Maybe there are some side characters who help or hinder the main character's journey through this chaotic world.
I don't have enough information to know who the main characters are in this graphic novel.
Most likely Naruto would be one of the main characters. Since it's Naruto - centered as the title implies. There may also be some original Western - inspired characters created for this fanfiction.
Obviously, Naruto would be one of the main characters, just in his new 'dark lord' role. Sasuke could also be a major character, as his relationship with Naruto is so central in the original series. Their dynamic would likely be very different in this fanfiction, perhaps becoming more of an adversarial relationship.
