How could a fanfiction about Naruto and Rias having a baby start?

Well, it could be really interesting. Naruto has his own world of ninjas and Rias is from a different supernatural setting. Maybe the baby would inherit Naruto's strong will and Rias' special powers. The story could focus on how they raise the baby in a world that is a blend of their two different universes. They might have to face challenges from both sides, like Naruto's old enemies and Rias' demon - related issues.

One way it could start is that Rias is on a mission to explore different worlds for some reason related to the devil world. She accidentally ends up in Naruto's world. Naruto, being the curious and friendly person he is, offers to help her. As they journey together, they learn about each other's cultures and powers, and the attraction between them begins to grow, leading to a relationship and eventually marriage.

In fanfiction, if Issei and Rias have a baby, it could be a story full of new adventures. The baby might inherit unique powers from both of them. For example, Issei's boosted gear power and Rias' devil abilities. Their friends would surely be excited and protective. The story could focus on how they raise the baby in a world full of different species like devils, angels and fallen angels. It would also show how they balance their duties as leaders and parents at the same time.

The impact would be significant. In the Naruto universe, a baby from Naruto and Sakura would symbolize a new hope. Since Naruto is a hero and Sakura is a strong kunoichi, their child would be expected to carry on their legacies. Politically, it could strengthen the bonds between different villages. If the baby shows great potential, other villages might try to form alliances through marriage or other means in the future. Emotionally, it would be a big deal for their friends like Sasuke, who might see it as a sign of a new era of peace and stability.

For Naruto, becoming a father would make him more responsible and cautious. He would no longer be just the carefree ninja. Karin, on the other hand, might become more nurturing. She has always been strong - willed, and with a baby, she could show a softer side. The baby would be a catalyst for their growth as characters.

It could be Hinata. Since they are in a relationship in the original series, it would be a natural choice. Hinata would be a loving and caring mother, and her gentle nature would be a great influence on the baby.

Well, the plot could involve Naruto and Samui realizing they have feelings for each other. Maybe they go on some adventures together first. Then, when they find out Samui is pregnant, Naruto could be super protective. He'd want to make sure she and the baby are safe from any threats in the ninja world. And perhaps the baby would inherit some unique abilities from both of them, like Naruto's chakra control and Samui's stealth skills.

One possible plot could be that Naruto and Hinata are adjusting to their new life as parents. They might face challenges like Naruto's busy Hokage duties and Hinata trying to balance taking care of the baby and her own ninja training. For example, Naruto might miss important baby milestones because of a mission, but Hinata is understanding and they work through it together.

It could start with Hermione realizing she is pregnant. Maybe she's in the middle of researching some ancient magic in the library at Hogwarts when she suddenly feels unwell and realizes what's going on. She then tells Harry, and they both are filled with a mix of joy and fear.

One possible plot twist could be that the baby has some unique power that neither Naruto nor Tsunade possess. Maybe it has the ability to control time, which causes all sorts of chaos and also attracts the wrong kind of attention from villains who want to use the baby's power for their own evil deeds.
