One possible plot is that Naruto is having trouble understanding the emotions of his friends. Kurenai, being good at reading people, could step in to help. She could use her experience and wisdom to teach Naruto how to better empathize. For example, she might share her own experiences of dealing with her team members in the past. This would not only strengthen Naruto's relationships but also make him a more well - rounded ninja.
In such a fanfiction, maybe Kurenai could help Naruto with his stealth skills. Since she's an expert in genjutsu, she might teach Naruto how to use genjutsu more effectively in battles, like against the Akatsuki members.
Well, it could be that Naruto is in a tricky situation, perhaps poisoned by an enemy's jutsu. Kurenai, with her knowledge of various ninja arts, might help him find an antidote. She could also use her genjutsu to keep Naruto calm while he recovers, so he doesn't accidentally use too much of the Nine - Tails' chakra. And together they could form a plan to take on the enemy who poisoned him.
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.
Perhaps Naruto owns Kurenai in the sense of protecting her. In the fanfiction, there could be a new and powerful enemy threatening the village. Naruto, with his great power, takes it upon himself to keep Kurenai safe. He stands in front of her in battles, and his actions and decisions end up dictating how Kurenai can move and act, thus 'owning' the relationship in terms of protection.
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.
One possible plot could be that Naruto has to go on a special mission with Kurenai. They might be sent to a hidden village where they discover a new type of jutsu that is being misused. Kurenai's genjutsu skills and Naruto's rasengan could be combined in unique ways to fight against the villains using this jutsu.
