Well, their friendship could inspire other characters. For instance, the younger ninja in the village might look up to them and see that friendships can cross different ninja styles. If Naruto, known for his unorthodox and powerful ninjutsu, can be friends with Tenten, who is a master of weaponry, it shows that different skills can complement each other.
It could also change the dynamics between their respective friends. Naruto's friends like Shikamaru and Choji might start to interact more with Tenten and her friends. This could lead to new team - ups during missions or just more social interactions in the village. Maybe they would all start training together and share their unique skills, which would make the whole village stronger.
For Naruto, Tenten's discipline with her weapon training could inspire him to be more focused in his own training. He might start to practice new techniques with more precision.
Their friendship could start with a simple accident. For example, Naruto could be exploring a new area in his own world that has some strange energy. This energy could be a portal that sucks him into PewDiePie's world. PewDiePie might be filming a video when Naruto suddenly appears. At first, PewDiePie is scared but Naruto's friendly nature quickly calms him down. They start to communicate, Naruto using some basic language skills he's learned from his travels and PewDiePie trying to understand this strange new person. And from that moment on, they start to form a friendship.
Naruto could develop a deeper understanding of Tenten's fighting style. Since he has to capture her, he'll study her moves closely. This could lead to him respecting her skills more. Tenten, on the other hand, might become more open - minded about Naruto's unorthodox methods. She may start to incorporate some of his spontaneity into her own fighting style.
Sakura would probably be shocked at first, but then she'd be supportive. She might offer her medical skills to help with Tenten's pregnancy. Shikamaru would likely think it's a troublesome situation but would also offer his strategic advice on how to handle things. Kakashi would be his usual calm self and give them some wise words about responsibility and family.
For Kakashi, it would be a relief. He's always been worried about Naruto and his power. Now that Naruto has Kurama as a true friend, he knows that Naruto has more control and support. Their friendship could also inspire new training methods in the village. Maybe the idea of forging a bond with one's tailed beast could be explored more, leading to different ways of teaching the younger ninjas.
In this fanfic, Naruto's character development could be quite significant. He may start to view his powers not just as tools for fighting but also as things that can have a major impact on those around him. This could lead to a more mature Naruto. Tenten might find new aspects of her own abilities. For example, if the coating has some unique properties, she could try to incorporate it into her combat style. Their relationship would evolve as they face this strange situation together. They would communicate more, sharing their fears and hopes. Naruto might share his insecurities about his powers and Tenten could share her dreams of becoming a better kunoichi. Through this mutual sharing and support, they would both grow as characters and their friendship would be deeper and more meaningful.
For Kakashi, it would be like losing his student all over again. He has trained Naruto and seen his growth. His death would make Kakashi question his own role as a teacher and mentor. He might become more withdrawn and blame himself for not being able to prevent Naruto's suicide.
It could also have an impact on the other characters. Their friendship could be an example for others in Konoha, promoting more unity among the ninja. This unity could be crucial in facing larger threats, like the Akatsuki. Instead of individual efforts, Konoha could present a more united front, all because of Naruto and Neji's friendship.
Tenten would likely be deeply traumatized. Naruto was not only a comrade but also a symbol of hope and strength. His death in protecting her would make her feel guilty. She might start to question her own worthiness of being saved at the cost of Naruto's life.
It could strengthen his relationships. If his heritage shows he has noble origins, people might respect him more and be more willing to be his friend or ally.
