One possible plotline could be that Naruto and Rin Inuzuka team up for a mission. Maybe they have to protect a small village from a group of bandits. Along the way, Naruto's determination and Rin's skills with her Inuzuka clan techniques combine to defeat the enemies. They also learn from each other, with Naruto teaching Rin about his unique jutsu, and Rin showing Naruto how to better communicate with animals like the Inuzuka do.
Another plot could be that Naruto and Rin Inuzuka discover a hidden power within their combined lineages. They are on a quest to understand and control this power. They face many challenges and obstacles from other ninja clans who fear this new power. Through their friendship and mutual trust, they manage to overcome these difficulties and become stronger ninja as a result.
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.
Another aspect could be his relationship with the Inuzuka clan members. Naruto might face some initial resistance as he is an outsider, but over time, he wins them over with his determination and kind heart. He could grow up with Kiba and become like a brother to him. They would train together, and Naruto would adapt to the Inuzuka clan's more wild and rough - and - tumble way of life.
Their relationship could start as comrades. Naruto, being the friendly and outgoing type, would be open to working with Rin Inuzuka. As they spend more time together on missions, they'd start to respect each other's skills. Then it might develop into a deeper friendship. Naruto's positive attitude could inspire Rin, and Rin's loyalty could make Naruto trust her more.
One possible plotline could be a what - if scenario. For example, what if Obito didn't 'die' and he and Rin finally confessed their feelings and shared a kiss. Another could be a time - travel plot where Obito gets a chance to go back and change things, leading to a kiss with Rin.
One possible plotline could be them dealing with the challenges of Kakashi's ninja duties while maintaining a marriage. Another could be Rin adjusting to life in Kakashi's village.
One possible plotline could be that Rin, with her medical skills, helps Naruto when he gets injured during a difficult mission. She could also offer him emotional support, like when he's feeling down about not being able to save someone. Another aspect could be Rin teaching Naruto some of the things she learned from her time in Konoha, which could help him in his ninja journey.
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.
It could be that in this fanfiction, Naruto is on a mission with an Inuzuka member and they get into a difficult situation. Naruto shows extraordinary courage and loyalty during this mission. This impresses the Inuzuka clan so much that they start to consider him as one of their own. He then starts training with them, learning how to communicate better with the Inuzuka dogs and using their clan - specific jutsu, and he also becomes part of their family - like structure within the clan.
It's hard to say exactly as this is a very unusual concept for Naruto fanfiction. But perhaps it could involve a character having some sort of medical condition that causes incontinence and how they deal with it while still being a ninja. Maybe they have to hide it from their teammates to avoid being seen as weak.
