Another idea for the fanfiction could be a time - travel plot. What if Ichigo somehow travels back in time and meets a younger Rangiku? He could influence her growth and development, and in turn, she could have an impact on his view of the past. This would create a complex web of cause and effect, and it would be interesting to see how their actions in the past would shape the future of the Bleach world they know.
Byakuya doesn't die. The manga plotlines and developments always find a way for him to persevere and stay in the storyline. His skills and determination help him survive the tough circumstances presented.
There's a fanfic called 'Silent Bonds'. In this one, the author delves deep into their past. It shows how Rangiku's presence has influenced Toshiro's growth as a Soul Reaper. The writing style is really engaging, and it gives a lot of insights into their personalities. You'll find their interactions very interesting, especially when they're training together.
A fanfiction could also explore how they deal with loss together. Both have experienced losses in their lives. They could find solace in each other's company and share their stories of grief. This would create a very emotional bond between them. It could also lead to a moment of self - discovery for both characters as they see how the other has coped with difficult situations.
The relationship dynamic between them needs to be well - developed. It could be a slow - burn relationship where they gradually realize their feelings for each other. Or it could be a story about their strong friendship. In a great fanfic, their interactions should feel natural, like when they're having a conversation about their duties as Soul Reapers.
One possible plot could be that after all the battles in Bleach, Ichigo discovers a new side of Rangiku and they fall in love. They get married secretly to avoid the chaos it might cause in the Soul Society and the human world. Then they have to face the challenges of hiding their relationship from their friends and families while also dealing with new threats that target them because of their union.
I don't have a specific 'bleach rangiku lemon fanfic' to recommend because such fanfics might violate the original intention of the work and may also have inappropriate elements. But generally for 'Bleach' fanfics about Rangiku, some might explore her backstory, like how she came to be in the Soul Society. You can search for these on various fanfic platforms and look for ones with high ratings and good reviews.
There are quite a few out there. One popular one might be 'The Unlikely Bond' which explores how Ichigo and Rangiku's relationship develops in a post - Bleach world where they end up getting married. It has great character development and an interesting plot.
Hiyori remained alive in the Bleach comic. The creators of the comic didn't choose to kill off her character. Instead, she was involved in various plot developments.
