One possible plot could be that Byakuya's new wife is from a different clan and has some unique powers. Ichigo and Rukia initially suspect her motives towards Byakuya. As the story progresses, they discover that she is actually trying to protect Byakuya from an ancient threat that is coming back to haunt the Soul Society. Along the way, Ichigo and Rukia help her in her mission, and they all form an unexpected bond.
Here's another plot idea. Byakuya's new wife could be a human who was somehow brought into the Soul Society. Ichigo, being a half - human, half - Soul Reaper, can relate to her situation. Rukia, on the other hand, is cautious as this is an unusual situation. The wife starts to show some special abilities that no one expected. This draws the attention of both good and bad forces in the Soul Society. Ichigo, Rukia, and Byakuya must protect her while also trying to figure out what her true nature is and where her powers come from. There could be a lot of action, mystery, and character development in this kind of plot.
A plotline could involve Byakuya's new wife being from a different clan or group. She might see Ichigo's power and Rukia's connection to him as a threat to Byakuya or their family. So she starts plotting against them. Meanwhile, Ichigo and Rukia are trying to figure out what's going on and how to protect their relationship, whether it's a platonic or romantic one. This could lead to battles, both physical and emotional, and a lot of character development for all involved.
Searching for a very specific fanfic like this can be like looking for a needle in a haystack. Firstly, on fanfic platforms, try using different combinations of the character names in the search bar. For example, you could try 'Byakuya new wife Ichigo Rukia' or 'Byakuya + new wife + Ichigo + Rukia'. If that doesn't work, consider reaching out to Bleach fanfic authors directly. You can find their contact information on their author pages on fanfic websites. Ask them if they have any ideas or if they might be interested in writing such a story. Additionally, some fanfic platforms have recommendation sections where users can suggest stories. Check those out as well.
I've read a few fanfics with these characters. A really interesting one was where Byakuya had to team up with Ichigo to rescue Rukia from a new and powerful enemy. The fanfic did a great job of showing Byakuya's reserved yet powerful nature, Ichigo's determination, and Rukia's strong will. It was full of action scenes and also some really touching moments between the characters. You can often find such fanfics on dedicated fanfic websites by using the relevant tags.
Well, I haven't come across a 'Byakuya, new wife, Ichigo x Rukia' fanfic directly. However, when looking for it, consider using advanced search options on the fanfic platforms. For example, on Archive of Our Own, you can filter by tags like 'Bleach', 'Ichigo x Rukia', and maybe something related to Byakuya in a more general sense. You could also check out the works of popular Bleach fanfic authors, as they might have created something along these lines.
Well, it could be about their adventures together after the main events in Bleach. Maybe they go on a mission to a new realm and face new enemies while strengthening their bond as friends and comrades.
Well, it could be a story of Byakuya and Rukia's unspoken bond. Since Byakuya is a very stoic character and Rukia is more open - hearted, the fanfic could play around with how they communicate without really saying much. It might also involve Rukia's friends in the Soul Society and how they interact with Byakuya. There could be a sub - plot where Rukia tries to make Byakuya more social or at least understand the modern ways of the Soul Society better.
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.
One possible plot could be that Byakuya has been secretly watching over Ichigo all his life. He could use his influence in the Soul Society to protect Ichigo from afar, while Ichigo has no idea of their relation. Eventually, the truth could be revealed during a major battle when Byakuya steps in to save Ichigo in a way that makes it obvious they are related.
Maybe Aizen has created a false asylum as part of a new experiment. He lures Ichigo and Rukia into it, and they have to find a way to escape while also dealing with the illusions and traps Aizen has set up. In the process, they could learn more about Aizen's motives and past, and perhaps even find a way to defeat him once and for all.
One possible plot could be that Ichigo and Rukia are paired for a school project. They start off not getting along very well because of their different personalities. Ichigo is impulsive and Rukia is more reserved. But as they work together, they gradually learn to understand and respect each other. They might face challenges like finding a suitable topic, dealing with difficult classmates who try to disrupt their work, and finally presenting their project successfully which also strengthens their friendship.
