The implications would be quite complex. Firstly, in the context of the Bleach world, where there are strict social structures and hierarchies, this would be a major scandal. Byakuya, being a noble, would have his reputation at stake. Rukia, too, would face a lot of scrutiny. Emotionally, it would add a whole new layer to their relationship. They would have to navigate not only their existing feelings of respect and family - like connection but also the new dynamic of being about to have a child together. This could also lead to changes in their relationships with other characters. For instance, Renji might have a very different reaction compared to Ichigo, and the Soul Society as a whole would have to deal with this unexpected development.
I haven't come across a fanfiction where Byakuya gets Rukia pregnant specifically. It's important to note that while fanfiction allows for creative interpretations, some concepts can be a bit out of place. In the context of Bleach, their relationship is more of a family - like bond in the original story, so this kind of plot would be a very different take on their characters.
If there were such a fanfiction, the implications would be far - reaching. Firstly, it would change the power dynamics between Sesshomaru and Kagome. Their relationship would become more complex due to the pregnancy. Socially, within the fanfiction world they inhabit, it would likely cause a scandal or at least a great deal of gossip. Emotionally, both characters would have to face new feelings and responsibilities. Sesshomaru, who is often aloof, would need to come to terms with being a father, and Kagome would have to deal with the consequences of having a child with a demon in a world that may not be fully accepting. Also, the story would have to deal with how their families and friends would react to this unexpected union and pregnancy.
One possible plot could be that rukia and byakuya accidentally end up taking care of a baby. They initially struggle as they are not used to this situation. Byakuya with his strict nature tries to impose order while rukia is more lenient. As they care for the baby together, they start to understand each other on a deeper level and their relationship grows stronger.
Rukia's kind and empathetic nature would make her very nurturing towards the baby. She would be quick to comfort the baby when it cries and would be very hands - on in its care. Byakuya, on the other hand, with his reserved and disciplined personality, might seem a bit cold at first. But his sense of duty would ensure that he provides for the baby's needs in a very organized and efficient way.
The implications would be significant. First, it would change the entire perception of the characters. Jacob and Renesmee's relationship has certain boundaries in the original. This fanfiction concept would break those boundaries and create a whole new set of relationships and family dynamics. It might also face a lot of criticism from the fan community for straying too far from the source material. Additionally, it could raise ethical questions about the nature of the relationship depicted in the fanfiction, as Renesmee has a unique origin in the original story.
If such a fanfiction existed, it would likely stir up a lot of controversy among fans. Some might see it as a creative exploration of the characters' relationship, while others would think it's completely out of character and against the essence of the original story.
The plot could take a very different turn. If Harry gets Narcissa pregnant, it might change the power dynamics in the wizarding world. The Malfoy family's reputation would be forever altered. And Harry, being the father, would have new responsibilities. He might face opposition from those who oppose any form of 'forbidden' relationships. There could be a lot of secrecy involved at first, with the two trying to figure out how to handle this unexpected situation.
One implication could be a significant change in the relationship dynamics between Sasuke and Fem Naruto. It would add a whole new layer of complexity to their relationship, perhaps forcing them to face responsibilities and emotions they hadn't before.
One plot point could be how the Soul Society reacts to the news. Since Byakuya is from a noble family, there might be a lot of expectations and politics involved. Another could be Rukia's own concerns about being a mother while still being a Soul Reaper. She might worry about how to balance her duties.
Yes, it can be quite popular. Many fans of the Bleach series are intrigued by the potential relationship between Rukia and Byakuya. Their complex dynamic in the original series gives a lot of room for fanfiction writers to explore different aspects of their relationship, from a deeper friendship to a romantic love. This allows fans to delve into scenarios that might not be fully explored in the official storyline.
