Naruto would probably be very confused at first. He trusts Sasuke, even if it's a Fem Sasuke in this fanfiction, and he wouldn't expect to be kidnapped by her. So, his initial reaction might be to try and talk to her, asking her why she's doing this.
She would probably be very angry at first. Naruto is a headstrong character, and being kidnapped against her will would make her furious. She'd likely try to fight back immediately, using whatever skills she has at her disposal.
Well, in this kind of fanfiction concept, it could be a very interesting plot twist. Naruto, being female, might have some strong motives for kidnapping Sasuke. Maybe she believes she can protect him better this way from the various threats in the Naruto world. It could also lead to a different kind of relationship development between them, far from the traditional friendship or rivalry.
One possible motive could be to force Naruto to understand his own power. Sasuke might think that by kidnapping Naruto, he can push Naruto to a situation where he has to tap into his full potential. Maybe Sasuke feels that Naruto has been relying too much on his friends and needs this shock to grow stronger on his own.
Also, it allows for a deeper exploration of gender roles in the Naruto universe. A fem Naruto might face discrimination or different opportunities compared to male Naruto. How Sasuke responds to this, whether he becomes more protective or if it makes him view her differently, is a fascinating aspect. It gives readers a chance to see the Naruto world through a different lens, one that challenges the traditional male - centered narrative.
Naruto could use her shadow clone jutsu. She could create multiple clones while Sasuke is distracted and then make her escape. Since she has a large amount of chakra, she can afford to create a lot of clones to confuse Sasuke.
Their relationship can be developed through shared experiences. For example, going on dangerous missions together. Each time they face a new threat, they learn more about each other's abilities and personalities. Naruto's positive attitude can slowly break down Fem Sasuke's more reserved nature.
One common theme is friendship. Since Naruto and Sasuke's relationship is so central in the original series, in fem versions, their friendship or evolving bond is often explored. Another theme is rivalry, but with a different female - centered dynamic. For example, how they compete in a world that might have different expectations for female ninjas.
The Hidden Leaf Village would surely launch a rescue mission. This would involve characters like Kakashi, Sakura, and the other ninja. Their efforts to find Naruto would be a major part of the story. Meanwhile, Sasuke might be moving Naruto from one location to another to avoid being caught, which would add more twists and turns to the plot.
Well, in this fanfiction, perhaps Itachi is being manipulated by some dark force. He kidnaps fem Naruto because he's under the control of this force which thinks that Naruto, being female in this version, holds the key to some sort of ancient prophecy. Itachi is then in a struggle between his loyalty to the village and the commands of this dark entity.
