A fanfic could focus on the backstory of the Kamishiro brothers. Explore their childhood, how they discovered their powers, and what led them to become who they are. Maybe there was a tragic event in their past that shaped their personalities and made them so close to each other.
First, know the characters well. Study their personalities, motives, and relationships in the original work. This will help you write them in a way that is consistent. For example, if one brother is more impulsive, show that in your fanfic.
Rize's older brother, Takumi, was different from the other Kamishiro family members. While Rize was known for her alluring and dangerous nature, Takumi was more of a thinker. He spent his days researching about the ghoul society, trying to find a way for ghouls and humans to coexist. He was often in his study, surrounded by old books and papers. But when it came to Rize, he was always there for her. He would listen to her problems, whether it was about her struggles with her ghoul instincts or her difficulties in dealing with other ghouls in the area.
In the fanfic, Rize and her older brother had a complex relationship. Her brother was always looking out for her. He was like a shadow, silently protecting her. Rize, on the other hand, sometimes resented his over - protectiveness. But deep down, she knew he was the only one she could truly trust. They shared a bond that was unbreakable, forged through the hardships of being ghouls in a human - dominated world.
I think a 'brother to lover' fanfiction about Rize Kamishiro might explore complex emotions. It could delve into the initial bond of brotherhood and how it gradually transforms into romantic love. Maybe it would show their internal struggles as they deal with this shift in feelings, especially considering the social taboos often associated with such a relationship in many cultures.
One aspect that could make it appealing is the exploration of deep emotional connections. Moving from a brotherly bond to a romantic one involves a whole range of emotions like confusion, guilt, and ultimately, deep love. The 'OC' in the fanfiction can also introduce fresh perspectives and storylines that can enhance the overall allure of the narrative. It allows for creativity in how the relationship unfolds and how the characters interact with this new situation.
One idea could be to explore the backstory of Rize's brother. Maybe he was involved in some secret ghoul society before Rize became known. You could start with a scene where he is on a mission for this society, which then ties into how Rize's life is affected.
One idea could be to focus on the chaos that might ensue during the wedding preparations. Since there are so many brothers, each might have their own idea about how the wedding should be. For example, one brother might want a grand, traditional wedding while another might prefer a more modern and simple affair. This could lead to some interesting arguments and compromises among the brothers as they all try to make the day special for the couple.
Another fanfic could involve a plot where the Dixon Brothers are descendants of a long - lost wizarding family related to Hogwarts. They discover their magical heritage through a series of strange events. As they enter the wizarding world, they have to learn magic quickly while also dealing with the political and social aspects of the wizarding community, all with Harry Potter as their guide.
A fanfic could focus on Rize teaching Kaneki how to fully embrace his ghoul side. She could show him how to use his powers more effectively and how to hunt without attracting too much attention. In return, Kaneki could teach Rize about human emotions and values, which she might have lost touch with over the years of being a ghoul. This exchange could lead to a deep bond between them.
Some fanfic ideas might include a story where one of the siblings gets into trouble and the others have to come to their rescue. It could be legal trouble, like being wrongly accused of something. Or it could be about a relationship problem that one is having, and the siblings use their own experiences and wisdom to help them through it.
