Rukia would probably be very critical at first. Since she is quite serious, she might nitpick the inaccuracies in the fanfiction. But she might also secretly enjoy the ones that show her in a positive light, like those highlighting her friendship with Ichigo. In the Bleach universe, characters are used to their own stories, and fanfiction would be a whole new and unexpected take on their lives. The zanpakuto spirits might also have interesting reactions if they could read, as they have their own personalities and might be offended or flattered by how they are depicted in the fanfictions.
For the Soul Society, if the captains read fanfiction, it might disrupt their normal order. For instance, Byakuya might read a fanfiction that portrays his family in a different way. This could make him question some of his long - held beliefs about his clan. And if enough characters start believing in the fanfiction - inspired ideas, it could completely change the power dynamics and relationships in the Bleach world. The Quincy might also get involved if they notice the characters in Soul Society acting differently due to the influence of fanfiction.
When a female Naruto meets Rukia, Rukia would probably be quite interested in Naruto's determination. Naruto, on the other hand, would be fascinated by Rukia's calm and collected nature. They could exchange stories about their respective worlds. Naruto might share tales of her adventures in the Hidden Leaf Village, while Rukia could talk about the Soul Society and her duties as a Soul Reaper.
Naruto would probably befriend Ichigo right away. They both have a strong sense of justice and a desire to protect their friends. Sasuke, on the other hand, might be more aloof at first. He could be intrigued by Urahara Kisuke's mysterious nature. Naruto would likely get along well with Orihime too, as she has a kind heart. Sasuke might have a more competitive relationship with Byakuya, seeing his power and discipline.
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.
Ichigo Kurosaki might be one of the main characters as he is central to the 'bleach' series. The short stories could further explore his growth as a Soul Reaper or his interactions with other characters in new situations.
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.
Without reading the fanfic, it's hard to say for sure. But it could feature the main characters from the 'Bleach' series like Ichigo, Rukia, and Uryu. Since they all have their own sense of duty in the original story, they might be the focus in this fanfic as well, perhaps with new aspects of their duties explored.
In many of these fanfictions, you might find popular characters like Naruto, Sasuke, Ichigo, and Rukia crossing paths. But it varies a lot based on the author's imagination and story direction.
The main characters would likely include Ichigo, as he is the protagonist of the original series. He might be facing new challenges in this future scenario. Renji could also be a main character, as his relationship with Rukia and his own growth arc make him an important part of the Bleach universe. And Aizen, even though he was a villain, could play a significant role if the fanfiction explores his possible return or his influence on the future events.
