Well, perhaps in the fanfiction, Naruto being Kurenai's sensei could lead to him teaching her some unorthodox methods. Since Naruto has his own way of doing things, he might introduce her to new ways of fighting or thinking that completely revolutionize her ninja skills. This could create interesting storylines where Kurenai has to adapt to Naruto's teaching style while still holding on to her own values.
In this fanfiction, a really cool plot twist could be that Naruto, as Kurenai's sensei, is actually from a different time or dimension. He has come to this world to train her for a specific purpose, like preparing her for a great battle that is to come in the future. This would add an element of mystery and a sense of grandeur to the story. Naruto could bring with him knowledge and powers that are not known in this world, and Kurenai would have to learn quickly to keep up with him.
One possible plot twist could be that Naruto discovers a long - lost family secret that has an impact on his marriage to Kurenai. Maybe it's a prophecy that his family was supposed to stay away from certain clans, and Kurenai's clan is one of them. This would create a lot of internal conflict for Naruto as he loves Kurenai but also feels a sense of duty to his family's legacy.
Perhaps Naruto's teaching methods are very different from what the Team 8 members are used to. He might focus more on emotional intelligence and teamwork rather than just combat skills. This could lead to some initial resistance from the team, especially from Shino who is very set in his ways. But over time, they come to realize the value of Naruto's approach and become a more well - rounded team.
If Kurenai became Naruto's sensei in fanfiction, Naruto might learn some unique jutsu related to genjutsu. Kurenai is a genjutsu expert, and she could potentially teach Naruto how to use genjutsu more effectively or even develop his own genjutsu - based attacks. This could add a whole new dimension to Naruto's fighting style.
A plot twist could be that their deaths were faked by themselves. They might have discovered a great threat to the village that required them to go undercover. So, they faked their deaths to deceive the enemy. Or, perhaps their deaths lead to the awakening of an ancient evil that was sealed long ago. And it turns out that their deaths were somehow a sacrifice to keep this evil at bay for a while, but now the remaining characters have to find a way to defeat it once and for all. This would completely change the direction of the fanfiction.
One possible plot could be that Naruto travels back in time. He then uses his knowledge of future events and his ninja skills to train Kushina. Maybe he helps her become an even more powerful kunoichi and also gives her advice on her relationship with Minato.
Well, perhaps in this fanfiction, Naruto travels back in time and becomes Kakashi's sensei. He could use his knowledge of future events to guide Kakashi in a different way. For example, he might prevent Kakashi from making some of the mistakes he made in the original story. Also, Naruto could introduce Kakashi to new forms of chakra control or combat strategies that he learned from his own adventures. This would change the dynamic between them and also have a significant impact on the events in the Naruto world as Kakashi is an important character.
Well, one possibility is that Anko could teach Naruto some unique jutsu. Maybe she'd focus on his stealth skills since she's good at that. For example, she could train Naruto to be better at sneaking around and surprising his opponents, like how she moves in the shadows.
The plot could involve Kurenai protecting Naruto more fiercely from the start. Since she is a jonin, she might be able to shield Naruto from some of the early discrimination he faced in the village. Also, Naruto could be more involved in the affairs of the genjutsu - related missions and training, and his relationship with characters like Kakashi and Iruka could be different as Kurenai would play a different role in his life compared to Kushina in the original story.
Their relationship could start off rocky as Kurenai might be hesitant to accept Naruto as her sensei. After all, Naruto is younger and has a very different style. But as time goes on, she would start to see the value in his teachings.
Well, maybe Naruto as a cold sensei could be really strict in training his students. He might not show much emotion but push them to their limits. For example, he could make his students do really tough physical exercises without much praise, just expecting them to meet high standards.
