A really interesting plot could be a time - travel fanfiction. Suppose Sakura somehow travels back in time and meets a younger Kisame. She tries to change his path, knowing the future he will have. This could involve a lot of complex character development as Sakura has to deal with the differences in their values and the knowledge she has of his future actions.
One idea could be a story where Kisame and Sakura are forced to team up during a mission in a strange, new land. They start off distrusting each other but gradually learn to respect one another's skills. For example, Kisame is impressed by Sakura's medical ninjutsu when she heals him from a near - fatal wound. Another plot could be set in an alternate universe where they are both students at the ninja academy together, and their different personalities lead to some comical and also some heartfelt moments as they grow up.
One plot idea could be a story where Kisame and Itachi are on a mission together in a mysterious land. They encounter various challenges that test their loyalty to each other and their organization. As they face these difficulties, they start to understand each other on a deeper level, sharing their past traumas and dreams. This could build a strong bond between them without any inappropriate content, focusing more on their friendship and mutual respect.
One idea could be that Fem Kisame is a reformed Akatsuki member who teams up with Naruto to take on a new threat to the ninja world. They start off not trusting each other but gradually learn to respect and rely on one another as they face various challenges together.
Well, a plot could involve Kisame's sister being a healer. Naruto gets seriously injured in a battle and she is the only one who can save him. As she heals him, they start to share their stories and dreams. This leads to her realizing that the Akatsuki's ways might not be right. Also, she could be in a love triangle between Naruto and a member of the Akatsuki, which would add a lot of drama to the story. There could also be a plot where she discovers a prophecy that Naruto is the key to saving the ninja world, and she decides to protect him at all costs.
One interesting plot could be that Naruto discovers a hidden power within Kisame's sword. Maybe during a battle, the sword starts to react to Naruto's chakra in an unexpected way, leading to a new form of combat for Naruto.
Another plot could revolve around Itachi and Kisame having a philosophical debate during a long journey. Since Itachi has his own complex moral code and Kisame is more straightforward in his loyalty to the Akatsuki, they could discuss the meaning of loyalty, power, and the end goals of their organization. This could lead to a deeper understanding between them or even a rift, depending on how the story unfolds.
Perhaps in the fanfiction, there's a parallel universe where Sakura and Syaoran are enemies. They have to figure out what has gone wrong and how to set things right. This would involve a lot of self - discovery and exploring the nature of their relationship in different circumstances. They would need to find a way to break the spell or whatever is causing this rift between them and restore their normal relationship in their own universe.
One interesting plot could be Kisame and Naruto teaming up accidentally during a mission against a common enemy. They start off distrusting each other but gradually learn to respect each other's skills.
Well, a great plot could involve a year - long competition in the Sakura world. Different characters compete in various challenges throughout the year, and there are a lot of ups and downs. There could also be a plot where a character has to endure a year of hardships away from Sakura but is constantly thinking about her. Or perhaps a story where a new character arrives in the Sakura - filled world and spends a year learning about its unique culture and traditions.
Perhaps Utakata is injured and Sakura has to take care of him. During this time, they share stories about their pasts. Utakata tells Sakura about his life as a jinchuriki and the struggles he has faced, and Sakura opens up about her own insecurities. This mutual sharing brings them closer and they start to see each other in a new light.
