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.
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.
The plot could revolve around a mission where they are forced to take care of a baby for some reason. This baby then turns out to be their own in a strange twist. Shikamaru is initially reluctant but slowly warms up to the idea of fatherhood. Sakura is more immediately attached. As they try to find out how this happened, they also grow closer as a couple and start to envision a future with their new family member.
One possible story could be that Sasuke returns to the village after his long journey. He and Sakura finally have time to be together. They discover they're going to have a baby. Sakura is both excited and a bit worried. Sasuke, though not very expressive, is secretly overjoyed. He becomes more protective of Sakura. As the pregnancy progresses, they start preparing a room for the baby. Sasuke might even go on small missions close to the village to get things for the baby.
One possibility could be that Sakura is under Tsunade's tutelage while Naruto is trained by Jiraiya. This would lead to different styles of training. Sakura would focus more on medical ninjutsu and precise chakra control like Tsunade. Naruto, with Jiraiya, would learn more about summoning jutsu and unpredictable combat styles. Their growth paths would diverge in interesting ways, affecting how they interact with each other and their roles in the village.
They become more united as they face the challenges of parenting together. Their relationship deepens as they share the joys and sorrows of raising a child.
One possible plot twist could be that Itachi's past actions as a double agent in Akatsuki are revealed in a new light because of the baby. Maybe his enemies try to target the baby to get revenge on him, but Sakura, being a strong kunoichi, defends the baby with all her might. This could lead to a series of battles and alliances being formed in the shinobi world to protect the new life.
A great plot idea could be that the baby has some sort of special power that no one has seen before. It causes both excitement and fear in the village. Sasuke and Sakura have to protect their baby from those who might want to use the baby's power for their own gain.
In fanfiction, one possibility could be that Naruto and Sakura's kids inherit their unique abilities. For example, their son might have Naruto's strong chakra and Sakura's medical ninjutsu skills. They could grow up in a village that has been rebuilt and is more prosperous than ever. The kids might also face new threats that require them to use their combined inheritances to protect the village.
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.
