Naruto might see the Akatsuki sister as a challenge. He's always looking to bring people to the 'right side'. So he would start by trying to understand her motives. Kurenai would likely be more strategic. She would observe the sister's behavior and try to figure out if she can be an asset or a threat. If the sister shows any signs of kindness or remorse, Kurenai might be more open to working with her.
Naruto would probably be initially cautious but also curious. He has a knack for seeing the good in people, so he might try to befriend the Akatsuki sister. Kurenai, on the other hand, would be more guarded. She is a more experienced ninja and would be wary of any Akatsuki member. But she also might see an opportunity to gain intel from the sister.
Naruto would approach the Akatsuki sister with his usual enthusiasm and belief in the power of friendship. He would try to engage her in conversations about her life and dreams, hoping to find a common ground. Kurenai, being a teacher and a ninja, would approach the situation with a more educational mindset. She might try to teach the sister about the values of the Hidden Leaf and how she can make a positive change in her life.
Naruto would probably be really confused at first. He respects Kurenai, so he'd be hesitant to fight back right away. He might try to talk to her and ask what's wrong.
One possible storyline could be a story of friendship and alliance. Maybe Naruto and Kurenai team up with an Akatsuki sister who has a change of heart. They could fight against the more evil elements within the Akatsuki together.
Naruto might be initially shocked and heartbroken. He is someone who values loyalty and friendship deeply, so being cheated on would be a huge blow to him.
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.
Naruto would definitely fight back. Despite being kidnapped, she has a strong will and a lot of chakra. She would use her Shadow Clone Jutsu to create distractions and try to break free from her captors. And she would also be yelling at them, trying to get them to see the error of their ways.
The other members of the Akatsuki would have mixed reactions. Some, like Itachi (if he were still alive in this fanfiction), might see Naruto as a glimmer of hope for the group to change its ways. He could work with Naruto to steer the Akatsuki towards a more positive path. But others, who are more set in their old ways, might resist Naruto's presence and try to undermine him. The villagers of the Leaf would be shocked and confused. They've always seen the Akatsuki as the enemy, and Naruto joining them would be a huge paradigm shift for them.
The Akatsuki members themselves would have mixed reactions. Some, like Itachi (if he were still alive in the fanfic), might see Naruto as a potential asset but also a threat to their long - term goals. Kisame might be amused by Naruto's presence and see him as a new source of entertainment. Meanwhile, the Leaf Village elders would be outraged. They would see Naruto as a traitor and start devising plans to either bring him back or eliminate him.
Sakura would probably be very angry at Kurenai. She's protective of Naruto and would demand an explanation. She might even try to heal Naruto right away if it was a physical injury.
Naruto would probably be very confused at first. He's always seen the Akatsuki as the enemy, so being taken there by Fem Itachi would be quite a shock. He might be on guard and constantly looking for a way to escape.
Some members might be skeptical at first. For instance, Kakuzu would be worried about how her presence could affect their money - making operations. But others like Itachi might see her as an opportunity to change the Akatsuki from within. He might try to guide her and use her positive energy to sway the group towards a more noble path.
