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.
They might be quite surprised. Some characters like Ichigo could be either amused or annoyed depending on how they are portrayed in the fanfiction. For example, if the fanfiction makes him seem weak when he sees himself as strong, he'd likely be irritated.
I'm not sure if 'bleach' in the sense of the chemical or the common household product can read fanfiction. But if you mean the anime/manga 'Bleach', it doesn't have the ability to read in the literal sense as it is a fictional creation. However, fans of 'Bleach' might read 'Bleach' - related fanfiction.
Well, some characters might try to change the future they read. For example, Ichigo might see a future where his friends are in danger and immediately start training harder to prevent it. He's always been the type to take action.
Some characters might be amused. For example, Ichigo might find it interesting to see how fans imagine his adventures in different ways. He could chuckle at some of the more out - there scenarios.
Ichigo might become more cautious. Usually he's quite impulsive, but seeing the future could make him think twice before acting. He doesn't want to mess things up more than they already might be in the future he saw.
It might seem strange at first. Naruto is so used to his own world of ninjas, chakra, and hidden villages. Reading about Soul Reapers and Hollows from Bleach fanfiction is quite a departure. However, Naruto is known for his open - mindedness, so he might just enjoy it as a form of escapism from his own often - dangerous adventures.
You can try some fanfiction websites like FanFiction.net. It has a large collection of 'Bleach' fanfictions. Just search for 'Bleach' on the site, and you'll get a list of relevant stories.
I really like 'Fairy Tail in the World of Bleach'. In this fanfiction, the Fairy Tail guild members find themselves in the Bleach universe. It's interesting to see how they adapt to the different rules and powers there. They also form new alliances and face common enemies, which makes for a thrilling story.
