A plot could involve Kurenai's pregnancy being a surprise to many. As she progresses through her pregnancy, she starts to train a young apprentice in the ways of the ninja. The apprentice becomes not only her student but also a source of support, learning about life and ninja values from Kurenai's experiences during her pregnancy.
The plot could involve Kurenai facing difficulties during her pregnancy. There could be threats to her and the unborn child, perhaps from an old enemy who sees this as a vulnerable time. She would then have to rely on her skills and the support of her village to protect herself. Or it could be about her dealing with the physical and emotional changes. She might struggle with mood swings and at the same time, be excited about the new life growing inside her. And of course, there could be a lot of focus on her preparing a nursery and getting baby supplies in a ninja - themed way.
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.
Well, perhaps in this fanfic, the pregnancy could be a result of a special mission or some sort of magic that binds Kurenai to a character. And Naruto, being the hero he is, gets involved to help Kurenai understand and deal with the situation. He could also help her face the reactions of the village, which might be mixed since Kurenai is a respected shinobi.
Well, perhaps in this fanfiction, Kurenai somehow gets involved in Naruto's life in a very maternal way due to some unforeseen circumstances. For example, she might be the only one who can understand a new power that Naruto has awakened. So, she decides to guide him like a mother would. She would teach him how to control this power, and also give him emotional support which he lacks so much. In the process, their bond grows stronger, and they face many challenges together, like fighting against new and powerful enemies who are after Naruto's power.
Perhaps there was a misunderstanding. Kurenai might have thought Naruto was involved in something bad. For example, she could have been misled to believe Naruto was working with a group of rogue ninjas. So she attacks him, and Naruto has to prove his innocence while also dealing with her attacks.
One possible plot could be that after the war, Naruto and Kurenai start to work closely together on rebuilding the village. As they spend more time together, they develop feelings for each other. Eventually, they get married and face challenges like dealing with the expectations of the village and Naruto's duties as a hero while also building their own family.
The plot might involve Kurenai seeing Naruto as a kindred spirit. Maybe she lost someone dear and sees in Naruto the same pain and determination. She adopts him and starts to teach him about the importance of family and bonds. Naruto could then grow up with a stronger sense of self - worth. He might also become more confident in his abilities earlier because he has Kurenai's guidance. This could change the way he approaches his training and his interactions with the likes of Sasuke and Sakura.
In this fanfiction scenario, Kurenai could also help Naruto with his emotional control. Naruto has a strong will but sometimes his emotions can get the better of him. Kurenai, with her calm and collected nature, could teach Naruto how to stay focused and in control during intense situations. For example, she could use her own experiences to show Naruto how to channel his emotions into strength rather than letting them cloud his judgment. This would not only improve his combat abilities but also his decision - making skills.
Well, it could be that Kurenai is somehow deceived into believing Naruto has done something really bad. Maybe she's tricked by an enemy who fakes evidence against Naruto. So, in her misunderstanding, she turns against him.
Well, it could be about Kurenai having some secret connection to Naruto as his sister. Maybe she discovers this truth and has to deal with the implications. For example, she might have to protect Naruto from new threats while also coming to terms with her new - found family relation.
