Lemon fanfictions usually involve adult - themed content which might not be suitable for all audiences. However, if you're specifically looking for Ichigo and Rukia - centered stories that are more on the romantic side without the 'lemon' aspect, there are many great ones out there. You could start by searching for stories with high ratings and positive reviews from other fans of the series.
There are quite a few out there. One that stands out is 'The Unspoken Promise'. In this fanfiction, Ichigo and Rukia have to face a new threat in Karakura Town. It's full of action and also shows their unwavering loyalty to each other. 'Soul Reaper Allies' is also good. It's about how they team up with other Soul Reapers and the interactions between Ichigo and Rukia during these missions are really well - written. 'Pathways of the Heart' is a more introspective fanfiction that explores their feelings for each other on a deeper level without any inappropriate content.
I really like 'Byakuya's Unseen Side'. This fanfic shows a different, more vulnerable side of Byakuya. It has some really interesting interactions with other characters from 'Bleach', like Rukia. It's a great read if you want to see a new perspective on his character.
Another characteristic often explored in fanfiction is his power. His swordsmanship and his zanpakuto's abilities are sometimes elaborated on in ways that go beyond what was shown in the original anime or manga. Fanfic writers might create new battles or training scenarios for Byakuya to show off his strength and skill, while also delving into how his power affects his relationships with others, either through envy, respect, or fear.
One great 'Byakuya Kuchiki Fanfiction' is 'A Noble's Path'. It delves deep into Byakuya's character, showing his internal struggles with his duties and emotions in a really engaging way. The writing style is vivid and makes you feel like you're right there in the Soul Society with him.
Many fanfictions also explore their personal growth through their relationship. Kuchiki Byakuya, with his strict and stoic nature, might be softened by Renji's more passionate and impulsive personality. Renji, in turn, could learn discipline and refinement from Byakuya. Their interactions can be a great source of character development in fan - made stories.
