It could involve the challenges she faces during her pregnancy. Maybe she has to deal with health issues or the reactions of those around her.
The plot might revolve around how her pregnancy affects her relationships. For example, her partner could be overly protective or there could be conflicts within her family. Also, she might be worried about how the pregnancy will impact her role in whatever story world she is from. There could be a build - up to the birth and all the emotions and events that come with it, like preparing a nursery or choosing a name.
I'm not sure specifically about a 'Kushina Raikagi' pregnant fanfic. There are countless fanfics out there in the fanfiction world, and it might be quite niche. You could try searching on major fanfic platforms like Archive of Our Own or FanFiction.net.
One possible plot could be that the Raikage and Kushina have a secret relationship. Their pregnancy could be a shock to the ninja world as it crosses village boundaries. It might lead to political tensions, with some seeing it as a way to unite the villages through their child, while others fear it as a threat to the balance of power.
One possible plot could be exploring how the characters around Kushina react to her pregnancy. For example, her friends could be excited and start preparing for the new arrival, like knitting baby clothes or planning a baby shower. They might also offer their support and advice on dealing with pregnancy symptoms.
The plot might revolve around a mystery that only they can solve. Maybe something related to an ancient artifact that has a connection to both the Uzumaki and Uchiha clans. As they search for answers, they have to overcome various obstacles and in the process, their friendship grows stronger.
The plot could start with Kushina having strange dreams about Aphrodite. As the story progresses, it's revealed that Kushina is actually a vessel for Aphrodite's spirit. Aphrodite starts to take over Kushina's body more and more. This causes a stir in the Naruto world as her new, more alluring and powerful presence affects the relationships between characters. Some might be drawn to her while others are suspicious. And she has to figure out how to co - exist with Kushina's original self and complete some sort of divine task in the Naruto universe.
Well, perhaps in this fanfiction, there could be a powerful enemy that they defeat together. In the process, their connection deepens. Naruti realizes his true feelings for Kushina. They then get married in a small, private ceremony among their closest friends and family. Soon after, Kushina discovers she's pregnant. This could lead to a story about Naruti becoming over - protective and Kushina trying to balance his concerns with her own independence during the pregnancy.
Well, it could start with Naruto and Kushina finding out about the pregnancy. Then, Naruto would be filled with joy and a sense of responsibility. He'd start learning about parenting from the elders in the village. Kushina would be busy knitting baby clothes and talking to the other women in the village. As the pregnancy progresses, they could face some small challenges like finding the perfect name, but overall it would be a story of love, hope and the building of a new family. There could also be a sub - plot about how the news affects the morale in the village, as everyone is excited for the new generation.
One possible plot could be that Naruto, with his godlike powers, is overprotective of Kushina during her pregnancy. He uses his powers to ensure her safety, like creating a special barrier around their home. He also shares his amazing adventures with their unborn child, by talking to Kushina's belly. And he might start training in new ways to be a great father in addition to being a hero.
One possible plot could be that Sakura somehow travels back in time and meets Kushina. Kushina, being Naruto's mother, could see some of Naruto in Sakura and they could bond over that. Maybe Kushina would teach Sakura some of her unique ninja techniques or give her advice on how to deal with difficult situations in the ninja world.
One possible plot could be that Naruto is somehow sent back in time and meets his mother Kushina. He gets to know her as a person, not just as the mother he never really knew. They could train together, and Kushina could share some of her unique Uzumaki clan techniques with Naruto.
