In a Naruto and Rin kissing fanfiction, the reactions would be diverse. Naruto might initially be caught up in the moment, but then have a flood of conflicting emotions. He could wonder how this would affect his relationship with his friends, especially those who knew Rin in a different context. For Kakashi, it could be a huge emotional blow. He might retreat into himself, or go on a quest to understand what led to this. The village elders might see it as a disruption to the social order. Among the fans, some would be excited by the boldness of the concept, seeing it as a chance to explore uncharted territory in the Naruto universe. Others would be critical, stating that it doesn't fit with the established personalities and story arcs of the characters. And then there are those who would be intrigued but also cautious, waiting to see how the writer develops the story further to either justify or retract this unexpected event.
One possible reaction is confusion. Fans who are used to a certain portrayal of Sesshomaru and Rin in the original source material might be caught off - guard by a kiss. They might need time to adjust to this new interpretation. On the other hand, some fans might be indifferent. They might not care much about the romantic aspect between the two characters and focus more on other elements of the fanfiction, like the action or the world - building.
Some characters might be shocked. For instance, Inuyasha could be initially stunned by the news, given his relationship with Sesshomaru. He might be conflicted between his dislike for Sesshomaru and his sense of what's right for Rin.
Well, it's not overly common as Rin was Kakashi's love interest in the original Naruto story. However, in the vast world of fanfiction, anything can happen. Some writers might explore this scenario to create unique or alternate storylines, perhaps to introduce a new dynamic or a what - if situation. But overall, it's not a mainstream plot device.
In a fanfiction, other Fairy Tail members' reactions could be complex. Elfman might struggle with his idea of 'manliness' and what this relationship means in that context. Levy would likely be excited for her friends and start looking for more fanfiction ideas based on this new development. Jet and Droy would be more on the side of just following Levy's lead. Juvia, who has her own strong feelings for Gray, might initially be a bit envious but then realize that everyone has the right to love in their own way and become more accepting.
Well, if Naruto and Sakura kiss in fanfiction, the reactions would be diverse. Fans who have been rooting for them, known as shippers, would likely be overjoyed. They would see it as a validation of their long - hoped - for relationship. However, fans of other pairings, like Naruto and Hinata or Sakura and Sasuke, might not take it so well. They might feel that it goes against the 'canon' in a way. Also, some more purist fans might think that it's too out of character for the original Naruto and Sakura. There are so many different perspectives within the Naruto fan community.
He might also become more reserved in future relationships. After being cheated on by Anko, Naruto could be more cautious when it comes to getting close to someone again, always having that fear in the back of his mind that he could be betrayed once more.
Naruto might be heartbroken. He's a very emotional character, so he could cry a lot and feel a deep sense of loss.
One possible plotline could be that fem Naruto, being a big admirer of Uchiha Rin, tries to follow in her footsteps. Maybe she wants to learn the same jutsu or have a similar impact on the village as Rin did.
One possible plotline could be that Naruto somehow ends up in the Fate/stay night universe and meets Tohsaka Rin. They could team up to face a common enemy that threatens both their worlds. Another plotline might involve a magical accident that fuses their powers and they have to learn to control it together.
Well, Naruto might be really confused at first. RWBY has a very different world setting compared to his own ninja world. He'd probably be intrigued by the unique characters and their powers in RWBY. For example, the use of Dust in RWBY might seem really strange to him as he's used to chakra-based abilities.
