Naruto would likely be involved. He has a strong bond with Kakashi and would surely try to rescue him. Sasuke could also be part of the story. Given his relationship with Itachi, it would add an interesting dynamic.
Well, one possibility could be that Itachi has some hidden motive related to the Uchiha clan's secrets. He might think Kakashi knows something crucial. So, he kidnaps him to interrogate him in a secret location.
There could be. There are a lot of creative fans out there who come up with all kinds of unique story concepts. However, I'm not sure exactly where you would find it. You could also check Naruto - related forums where fans might discuss and share such fanfics. It might take some time and effort to search for it though.
Another theme could be the challenges they face together. Given their roles in the Naruto universe, they might encounter various threats or obstacles that they have to overcome as a team, which can strengthen their bond in the story.
The theme of sacrifice is also prevalent. Given their complex situations, they may be required to sacrifice things for each other or for the greater good. This could be sacrificing their own safety, their reputations, or their relationships with others in the fan - created stories.
Naruto could be often involved. Since he's Kakashi's student, he might be part of the events that keep repeating in the time loop. Kakashi could be trying to protect Naruto in different ways each time the loop occurs.
The theme of redemption also pops up often. Since Itachi has a complex and somewhat dark past, the OC might be a factor in his journey towards redemption. And for Kakashi, the OC could be a new chapter in his life, helping him move on from past traumas or regrets. This makes for a very interesting dynamic in these fanfictions.
You can start by looking on fanfiction websites like Archive of Our Own (AO3). There are often tags related to 'Female Itachi' and 'Kakashi' that can help you narrow down the search. Many authors create unique stories in this pairing, exploring different scenarios and character dynamics.
Naruto would probably be one of the first to try and rescue Kakashi. He has a strong bond with Kakashi and would not stand by while his teacher is in danger.
Kakashi could use his Sharingan to analyze Obito's moves and find a weakness in his defenses. Since he has the Sharingan, he might be able to predict Obito's attacks and counter them effectively, eventually finding an opportunity to break free.
Itachi is likely to win. He's got powerful Sharingan abilities and strategic skills that might give him an edge over Kakashi.
