Yes, there are some out there. You can start by looking on fanfiction websites like FanFiction.net or Archive of Our Own. Just search for 'kisame and sakura' and you'll find various stories that explore their relationship in different ways.
One common theme is the clash of personalities. Sakura is often portrayed as strong - willed and determined, while Kisame is more of a stoic and powerful antagonist. So their interactions are filled with tension.
There could be. Fanfiction writers often come up with unique and unexpected ideas. Given the creativity in the fanfiction community, a story where Sakura is Kisame's daughter is not out of the realm of possibility. You can try searching on popular fanfiction websites to see if it exists.
Sakura might be initially hostile towards Kisame, given his reputation as an Akatsuki member. She would probably attack or be on guard. But Kisame, with his calm and somewhat menacing demeanor, would likely try to taunt her at first. For example, he could say things like 'Little girl, you think you can take on the likes of me?' However, as the story progresses, if they are forced to be around each other, they could develop a begrudging respect. Sakura might respect Kisame's strength, and Kisame could come to respect Sakura's tenacity.
You can find it on FanFiction.net. It has a large collection of fanfictions from various fandoms, and there's a good chance you'll find some stories about Kisame and Sakura's relationship there.
Another great one could be 'Kisame and Sakura: A Forced Bond'. This fanfiction starts with a strange jutsu that binds Kisame and Sakura together. They have to figure out how to break the bond while also dealing with their mutual distrust. It's full of action and character development.
One possible plot could be that Sakura, on a mission in a far - off land, encounters Kisame. At first, they are enemies as Kisame is from the Akatsuki and Sakura is a Konoha ninja. But then, they find themselves in a situation where they have to work together to survive against a greater threat, like a powerful ancient beast. As they fight side by side, they start to understand each other's motives and pasts, and Sakura begins to see that Kisame is not just a mindless villain.
Well, it could start with Sakura growing up in a different environment due to her relation to Kisame. Maybe she has some of his physical traits like his blue skin in a more human - like way. And she might be trained in different fighting styles that are a mix of Kisame's and the regular ninja training she gets in the village.
Since 'hard lemon' fanfiction is inappropriate, we can talk about their general characteristics in normal fanfiction. Sasuke is often depicted as a brooding and powerful character, while Sakura is shown as strong - willed and loving. In non - inappropriate fanfiction, their relationship might be shown as evolving from initial acquaintance to deep love, with Sasuke's cold exterior gradually melting due to Sakura's unwavering affection.
