One possible plot could be that Naruto and Naruko face various challenges while expecting their child. For example, they might have to deal with threats from old enemies who see their unborn child as a potential target. Naruto, being the Hokage, has a lot of responsibilities, and now he has to balance that with taking care of a pregnant Naruko. They could also have some cute moments, like Naruto trying to learn how to cook for Naruko to satisfy her pregnancy cravings.
Perhaps the plot could focus on the relationship between Naruto and Naruko during her pregnancy. They might have some arguments about how to raise the child, with Naruto having grown up without his parents and Naruko having a different view based on her own family experience. But in the end, they always come back together, and their love for each other and the unborn child grows stronger as the pregnancy progresses.
One idea could be focusing on how her friends and family react to the news. They might be surprised, excited, or worried. For example, her best friend could offer to throw a baby shower. Another idea is exploring how Naruko prepares for the baby, like setting up the nursery or choosing baby names.
The plot might involve the father of the baby as well. If the identity of the father is a mystery, Naruko could be on a quest to figure it out. Or if it's someone she knows, they could have different reactions to the news. For example, if it's a love interest, they might be overjoyed or terrified depending on their situation. There could also be elements of how the pregnancy affects Naruko's goals and dreams, whether she has to put them on hold or find a way to pursue them while being pregnant.
One possible plot could be that Naruko discovers she's pregnant during a time of relative peace in the village. She then has to deal with the mixed reactions of her friends and family. Some might be overjoyed while others worry about her safety and the future of the baby, especially considering her status as a ninja.
Her friends are likely to be part of it. A close female friend could be like a pregnancy buddy, sharing her own experiences if she has any. There might also be a mentor - like figure, an older woman who has been through pregnancy and can give Naruko valuable advice on everything from childbirth to raising a child.
One possible plot could be that Naruto and Erza are from different universes that somehow collide. They meet and fall in love against all odds. When they find out Erza is pregnant, they have to face challenges from both of their worlds. Naruto's ninja village might be skeptical about his relationship with someone from another realm, and Erza's guildmates in Fairy Tail could also have concerns. But together, they strive to protect their unborn child and find a way to make their two worlds coexist peacefully.
One possible plot could be that it's a misdiagnosis. Maybe Naruko is suffering from some strange illness or the result of a jutsu gone wrong that makes her appear pregnant. This could lead to a series of comical misunderstandings among her friends and comrades as they try to figure out what's going on.
One possible plot could be Naruto taking on the role of a mentor and father figure to Naruko. He might teach her all the ninja skills he has learned, like how to perform the Rasengan. And also, he could guide her in understanding the importance of friendship and loyalty, just as he experienced with his own friends in the original series.
A plotline could revolve around a love potion or some sort of magical spell. For instance, someone casts a spell on Naruto that makes him fall in love with Naruko, and the kiss is a result of that. But then, as the story progresses, they actually start to develop real feelings for each other. It could be a story of how they deal with these new - found emotions and the consequences of the initial spell.
Well, in a Naruko Clone Lemon fanfiction, the plot could involve the clone being created for some devious purpose by an enemy. But instead of following the enemy's orders, she rebels. She then meets a group of outcasts who teach her about real friendship. Regarding the 'lemon' part, it could be that she falls in love with one of the outcasts and they share some steamy, passionate moments as their relationship deepens.
One possible plot could be that Naruto and Ino unexpectedly find themselves in a relationship. Maybe they were paired up on a difficult mission and during that time, their feelings grew. Once Ino discovers she's pregnant, they face the challenges together. Naruto might be worried about how to balance his ninja duties with being a father, while Ino has to deal with the reactions of their friends and family, especially considering their initial relationship as just comrades.
