Red Kurenai was a Japanese light novel that had yet to have an official ending. After the novel was published, the author did not reveal any information about the ending. Therefore, the ending of Red Kurenai's novel was still unknown.
It would be more nurturing. Kurenai could cook for Naruto, like making him some of her special ninja - style meals. And she'd be there to listen to his problems, whether it's about his love life or his struggles with mastering new jutsu. Their relationship would be based on mutual trust and respect, just like a real sister - brother relationship.
In most Naruto fanfictions, there is no such plot where Kurenai cheats on Naruto because they don't have that kind of relationship in the original story. Kurenai has her own story arc mainly related to Asuma. So it's very unlikely to find such a scenario in regular Naruto fanfictions.
One possible funny fanfiction could be about Naruto trying to prank Kurenai and Anko at the same time. He sets up a series of comical traps around the training ground. Kurenai, with her sharp perception, starts to notice something is off but Anko just blunders right into the first trap, which sprays her with a bucket of colored water. Naruto is hiding in the bushes trying not to laugh out loud. Then Kurenai pretends not to notice Naruto's presence and lures him out by acting like she's falling for another of his pranks, and when he jumps out, she surprises him with a little genjutsu that makes him see a horde of angry Ankos chasing him.
Well, if Naruto and Kurenai had a child in fanfiction, it would be an interesting mix of their personalities. Naruto is all about never giving up and being super energetic, while Kurenai is calm and collected. The child might struggle with finding a balance between these two very different traits at first. And in terms of appearance, who knows? It could have Naruto's blond hair and Kurenai's red eyes perhaps.
In Naruto fanfiction, kurenai can play a significant role in helping. She has a deep understanding of the ninja world's politics and traditions. So, she could be used to educate new or young characters about these aspects. Her own personal story of loss and growth can also serve as an inspiration for other characters in the fan - written stories. For instance, if there's a character struggling with grief after losing someone, kurenai's experience could be a guiding light. Additionally, her genjutsu skills can be a key factor in solving mysteries or getting out of tricky situations in the plot of the fanfiction.
It could be Asuma. Since they had a relationship in the original series, it would be a logical choice. Their relationship was a significant part of the story, and having him as the father would add depth to the fanfiction, with the story exploring their future together as parents.
There could be. Fanfiction is a vast world where all kinds of scenarios are explored. But it's not something that is part of the official Naruto storyline. You can try searching on popular fanfiction websites like FanFiction.net or Archive of Our Own. Just keep in mind that the content may be quite different from what you expect based on the original series, and it may also not be appropriate in some ways.
Friendship is also a big theme. They come from different backgrounds but find common ground in their love for the village. Fanfics often show how they support each other through tough times, like when Kurenai is mourning the loss of a comrade and Naruto is there to cheer her up, or vice versa.
I'm not sure if there is such specific fanfiction readily available. Fanfiction varies widely across different platforms, and this kind of plot might be considered quite unusual and not conform to the general tone of the Naruto series in many respects. Some fanfiction platforms have strict rules about appropriate content, and this might not pass those rules in a lot of cases.
