One common theme is the exploration of female empowerment. Since Rin is often a male in the original, in these fanfictions as a female, she breaks gender barriers in the exorcist world. Another theme is the re - imagining of relationships. For example, her relationship with Yukio might be different, with new dynamics based on her being female.
Writers should first focus on his core traits. Rin is brave, so in any crossover, he should face challenges head - on. For example, if it's a crossover with a magical girl universe, he'd be the one jumping into danger to protect others. His loyalty to his friends and family is also important. In a crossover with a post - apocalyptic world, he'd do anything to keep his loved ones safe. Also, his hot - headedness should be there. If he's in a high - society crossover, he might get into arguments with the snobby characters because of his quick temper.
Many fanfics also focus on her powers and how she learns to control and use them. It's about her journey of becoming stronger both physically and mentally.
I've read a fanfiction where female Rin Okumura becomes a mentor to a young group of exorcists - in - training. This fanfiction focuses on her growth not just as a fighter but also as a leader. It shows how she imparts her knowledge and wisdom, all while dealing with the prejudices that come with being a female in a male - dominated exorcist world. It's a great read for those who want to see a more complex and developed female Rin Okumura.
One common theme is isolation. Often, when Rin is hurt, he may isolate himself from his friends and allies, thinking he's a burden or that he needs to deal with his pain alone.
However, in the realm of fanfiction, anything can happen. A writer could create an elaborate backstory where Naruto somehow ends up in the Blue Exorcist world and becomes Rin's father. Maybe there could be some sort of interdimensional travel or a really wild magic spell that links the two universes in a way that makes this relationship possible. But it would require a lot of creativity to make it believable within the context of the combined universes.
In many Rin Okumura white hair fanfictions, the theme of acceptance is prominent. Since his white hair makes him stand out, he has to learn to accept himself first. And also, others around him need to accept this new version of him. Another theme that can be found is the exploration of the unknown. The white hair could be a sign of something not fully understood in the world of the story, and the fanfiction delves into uncovering what that is.
One common theme is the struggle between Rin's demon nature and his human emotions in love. His demonic side might make him fear for the safety of his love interest. For example, in many fics, he's worried that his powers could accidentally harm the person he loves.
One common theme could be the exploration of Rin's unique identity in a yaoi context. His tail might be used as a symbol of his otherness or something that makes him stand out in the relationship. For example, it could be a source of fascination or a connection between him and his partner.
One possible theme could be self - discovery. If the tail has some special meaning or ability, Rin might go through a journey of understanding himself better. Another theme could be acceptance, both from himself and from others around him regarding this unique tail aspect.
