One common theme is the growth of their relationship. Since Rin is a demon - human hybrid and Shiemi has her own insecurities, their relationship development is often explored. For example, how they learn to trust each other more deeply.
You can start by looking on fanfiction websites like Archive of Our Own (AO3). It has a large collection of Blue Exorcist fanfics. Just type 'Blue Exorcist Rin x Shiemi' in the search bar and you'll get numerous results. Some might be focused on their relationship development, while others could be adventure - themed with their relationship as a side plot.
In the Blue Exorcist series, Rin and Shiemi have a very special relationship. They are friends and comrades in the fight against demons. While the series doesn't really point towards them having a romantic future in an obvious way, they do care deeply for each other. Rin is a strong - willed and hot - tempered character, while Shiemi is more gentle and kind - hearted. Their personalities could potentially complement each other well in a relationship. However, they are both focused on their exorcist duties for now. So, it's hard to say if they would ever end up together in that sense.
In the Blue Exorcist story, Rin and Shiemi's relationship has the potential to develop further. They have a certain chemistry that is evident in their interactions. Rin's brashness and Shiemi's calmness can create an interesting dynamic. But the story is full of other elements that could either push them together or keep them apart. For example, the threat of demons and the secrets within the exorcist community. Also, their own personal insecurities might hold them back. Overall, it's hard to put a number on the chances, but it's not impossible for their relationship to evolve.
Well, it could be a story where Rin and Shiemi are on a mission together. As they face a powerful demon, Shiemi gets injured. Rin, worried sick, nurses her back to health. In a moment of relief and new - found closeness after the ordeal, they share a kiss. It's a sign of their growing bond and the start of a deeper relationship.
It could end happily with them becoming a couple and continuing to fight demons together. They support each other in their exorcist duties and their relationship grows stronger over time.
I really like the fanfic 'Rin and Shiemi: A New Chapter'. It starts off with them going on a mission together. In this story, they have to rely on each other more than ever. It has some really cute moments where Rin tries to protect Shiemi in his own clumsy way, and Shiemi in turn helps Rin understand his powers better.
One great fanfic could be 'The Bond Beyond Worlds'. It delves deep into the relationship between Amaimon and Rin. The author beautifully portrays how their unique connection evolves over time, with Amaimon's mischievous nature clashing and yet also complementing Rin's more determined and righteous personality. It's filled with exciting adventures and some really heart - warming moments that fans of the pairing will surely enjoy.
One great Rin x Reader fanfiction is 'The Unseen Bond'. It beautifully portrays the relationship between Rin and the reader. The story focuses on how they meet and gradually develop a deep connection. It shows Rin's protective side towards the reader and how they face challenges together in the world of exorcism.
One popular theme is the exploration of their contrasting personalities. Amaimon is this wild and somewhat unpredictable demon, while Shiemi is more innocent and gentle. Fanfictions often play with how they interact with their different natures.
