Rukia is also probably a main character. She has a deep connection with Ichigo and is an important part of the Soul Society. In the 'bleach fade to black novel', she could be involved in the events that are causing the 'fade to black' situation, either trying to prevent it or being directly affected by it. Also, characters like Uryu Ishida, who has his own unique abilities and story arc in the Bleach universe, might also be important characters in this novel as they all come together to face whatever is going on in the story.
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.
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.
One idea could be that Ichigo Kurosaki from Bleach somehow gets transported to the Victorian era world of Black Butler. He could be mistaken for a demon or some kind of otherworldly being. Sebastian, being the ever - curious demon, might be intrigued by Ichigo's powers and his strong sense of justice. Another idea is that Ciel Phantomhive has to deal with Hollows suddenly appearing in his world. He enlists the help of the Soul Reapers from Bleach to combat this new threat. They could form an uneasy alliance where the Soul Reapers are not used to the complex politics of the Black Butler world, and Ciel has to figure out how to work with these super - powered beings.
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.
I'm not entirely sure specifically as it might vary. But generally, in the 'Bleach' series, it could be about the Soul Reapers, Hollows, and the battles in the spirit world. It may also explore the characters' backstories and their development in this dark and action - packed universe.
The combination of 'bleach' elements with the 'black joker' concept. It can bring a new and exciting twist to the familiar 'bleach' world. For example, new character dynamics can be created.
I'm not entirely sure as I haven't read it in detail. But generally, it might involve the characters from Bleach facing some new and dark challenges that could lead to a fade - to - black situation, perhaps some kind of near - death or extremely difficult ordeal for the characters.
Ichigo might gain new perspectives on his own power. If the fanfiction shows him in situations where he has to overcome even greater challenges, he could start to think about his own limits differently and maybe strive to be even stronger.
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.
