One possible plot could be that Naruto somehow travels back in time and meets Rin. He might try to prevent her tragic death. Since Naruto is known for his determination and never - give - up attitude, he could use his skills and knowledge to change the events that lead to her death.
Naruto would probably be very surprised. He has heard about Rin from Obito and Kakashi. So when he actually meets her, he might be at a loss for words at first.
One common theme is friendship. Since they are from different 'worlds' (in the context of the fanfiction), their coming together often leads to the development of a unique friendship. For example, they might learn about each other's strengths and weaknesses and support each other.
Their relationship could start off as a bit rocky. Inuyasha might be a bit impatient with Rin's naivete at first. But as they face challenges together, like fighting off demons or finding their way through a maze - like forest, they start to respect each other. Rin would look up to Inuyasha's strength, and Inuyasha would come to appreciate Rin's kind heart.
In a fanfiction world where Naruto and Rin have a baby, it could be a very interesting story. Maybe the baby would inherit Naruto's positive attitude and Rin's kindness. The story could explore how they raise the child in a world full of challenges and ninjas.
One possible plot could be that Inuyasha and Rin meet in a forest. Rin is now a bit older and has been trained in some basic self - defense skills. Inuyasha is initially cautious around her as she reminds him of his past with Kagome. But as they start to talk, they realize they both have a strong connection to Sesshomaru in different ways. They could end up teaming up to find a lost artifact that has some significance to Sesshomaru's past.
I'm not sure about the absolute best, but some authors might stand out if they have a deep understanding of both Naruto's and Rin's characters. Those who can capture Naruto's determination and Rin's kindness in their writing would be great. Look for authors who have a lot of positive reviews on fanfiction platforms.
There are indeed such fanfictions. In these stories, Rin's survival can have a huge impact on the other characters. For example, it could change Obito's path completely. Instead of becoming consumed by hatred, he might have a different future with Rin alive. Also, Kakashi's character development could take a different turn as well, since Rin was an important part of his past.
If Naruto and Rin had a baby in fanfiction, it might have unique abilities. Since Naruto has the Nine - Tails' power and Rin was a skilled kunoichi, the baby could inherit some extraordinary skills. For example, it could have a special form of chakra control.
One characteristic could be the exploration of an unlikely relationship. Since Naruto and Rin are from different storylines in a way, it makes for an interesting exploration of how their personalities might interact. For example, Naruto's determination might contrast or complement Rin's own qualities.
