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.
The father of the baby would be a key character. It could be a fellow ninja or someone from her past.
Sakura could be a potential character. She has a long - standing relationship with Naruto, and in this harem scenario, she might be jealous of Naruko at first but then come to accept the situation. Hinata could also be part of it. Given her love for Naruto, she would be an interesting addition to the harem, adding a shy and gentle dynamic.
Kakashi could also be a character in 'naruto and naruko harem fanfiction'. He can be the mentor figure, guiding Naruto and Naruko through different situations. His wisdom can influence how the harem relationships develop, for example, by giving Naruto advice on how to handle multiple relationships in a proper way.
Definitely the Naruko clone herself. Then there could be Sasuke. He might be intrigued by the clone and try to understand her existence. Also, Kakashi could be involved, maybe as a mentor figure to the clone, guiding her. As for the 'lemon' side, there could be some random attractive ninja from another village who catches the clone's eye and they develop a romantic relationship.
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.
There's also the possibility of pairing Naruko with Sirzechs. His powerful and noble nature could contrast well with Naruko's more brash and energetic personality. It could lead to a story where they have to work together to solve a major problem in the DxD world, and in the process, develop a deep connection.
It could be Sasuke. Their relationship has always been complex and full of twists. A pregnancy between them would add a whole new layer of drama and would force them to re - evaluate their relationship and their place in the village.
The main characters are obviously Naruto and Naruko. Naruto is a well - known ninja in the Naruto universe, famous for his determination and his powerful jutsu. Naruko would be an alternate version of Naruto, perhaps with some different characteristics while still sharing some of his core traits. In the context of the pregnant fanfiction, they are the expectant parents, and the story would likely revolve around their experiences, emotions, and the changes in their relationship due to the pregnancy.
Sasuke could be a great addition. He might initially be skeptical of Naruko's newfound bond with the Kyuubi, but then come to see the potential in it. Kakashi could also be included as he has a lot of knowledge and experience. He could offer guidance to Naruko on how to handle the Kyuubi's power. Another good character would be Jiraiya. He could have some interesting insights into the relationship between Naruko and the Kyuubi, having known about the Kyuubi for a long time.
Hal could be a very likely character. Since he was Alice's husband in the show, he could play a big role in the fanfiction. He might be the father, or he could be dealing with the news in different ways, like being supportive or having doubts. Another character could be Betty. As Alice's daughter, she would surely be affected by her mother's pregnancy. She could be helping Alice out or having her own emotional turmoil because of it.
