It's possible that new characters could be introduced as main characters in the 'new bleach story' as well. They could be from a different part of the Bleach universe, like a powerful Soul Reaper from a previously unmentioned division in the Soul Society, or a unique being from Hueco Mundo with special abilities that change the dynamics of the story.
If it follows the original pattern, Ichigo Kurosaki would likely still be a main character. He was the central figure in the original 'Bleach' series.
The main character is Ichigo Kurosaki. He is the substitute Soul Reaper. Rukia Kuchiki is also a key character as she is the one who initially gives Ichigo his powers. There's also Orihime Inoue, Ichigo's classmate and later an important ally with her unique healing and offensive abilities. Uryu Ishida, a Quincy, is another main character. And in Soul Society, Byakuya Kuchiki, a high - ranking Soul Reaper, is quite prominent.
I don't know specifically. But usually in Bleach novels, new characters are introduced to bring fresh storylines. They could be new Soul Reapers, Hollows, or even something from a different realm in the Bleach universe.
Perhaps one character could be a die - hard 'bleach' fan who is really good at the quiz. And the other character could be someone new to the 'bleach' world but is attracted to the first character's knowledge and passion during the quiz. So these two could be the main characters in this 'bleach quiz love story'.
Ichigo is one of the main characters. He's a human who becomes a Soul Reaper. Rukia is also important. She's the Soul Reaper who gives Ichigo his powers.
Most likely, Ichigo Kurosaki would be one of the main characters. He is the central figure in the 'Bleach' franchise. Rukia Kuchiki might also be a main character as she is crucial to the story's start in the original series.
I assume the main characters would be the ones from the original Bleach series like Ichigo Kurosaki. He was the central figure in the anime and manga, so it's likely he plays an important role in the novel as well.
There's also Uryu Ishida. He's a Quincy, which is a different type of spiritual being. His skills and his relationship with Ichigo add a lot to the story. And then there's Aizen Sosuke, a complex and powerful antagonist who has his own grand plans that drive much of the plot.
It's quite possible. New characters could add new dynamics to the story. They might be allies or foes of the existing characters, bringing new plotlines.
A new character could be a rogue Soul Reaper. This character has his own set of beliefs about how the Soul Society should be run and is constantly causing trouble for the Gotei 13. He might have a unique power that allows him to manipulate souls in ways that others can't. His role would be to be a constant thorn in the side of the established order, forcing the main characters to question the Soul Society's rules.
Ichigo would probably be one of the main characters. He's the protagonist of Bleach, so it makes sense for him to be at the sleepover. Rukia might also be there, as she has a close relationship with Ichigo. And Uryu could be there too, since he's another important character in the series.
