In the fanfiction, the plot could also focus on how Naruto and the mother support each other through difficult times. For example, if there is a threat to the village, they work together to protect it, with the mother using her own wisdom and Naruto his ninja abilities. Their relationship could be a source of strength for both of them and also inspire others in the village.
Well, one idea could be Naruto learning about the family values from the mother in the fanfiction. Maybe he discovers a new side of family life that he never had growing up. Another could be Naruto teaching the mother some ninja skills in return, creating a unique bond between them.
Maybe a fanfiction where the mothers come back to life for a short time. Naruto and Sakura get to experience a mother - child relationship they never had. Their mothers could offer advice on their ninja training and personal lives. For example, Naruto's mother could teach him more about his Uzumaki heritage and Sakura's mother could give her tips on how to be a better medic - ninja.
One idea could be Naruto finding a hidden journal of his mother's that reveals family secrets. Another could be his mother appearing in a dream to give him advice on how to handle a difficult situation in the village. Maybe she could also guide him in learning a new jutsu that was passed down in the family.
One idea could be a story where Naruto discovers a long - lost diary of Tsunade's mother. Through reading it, he uncovers secrets about the village's past that help him in his journey to become Hokage. For example, it might reveal hidden jutsu or the true nature of some old rivalries within the village.
Another plot could be that Naruto's adopted mother is secretly related to one of the main antagonists. She has to hide this fact from Naruto while also trying to guide him to be a great ninja. This creates a lot of internal conflict for her and also adds an interesting layer of mystery to the story as Naruto might start to notice some strange behavior from her.
It could also be some external enemies who see Naruto's new relationship as a weakness. They might target the mother to get to Naruto, thinking that by hurting her, they can make Naruto vulnerable. So these external forces would be antagonists trying to disrupt their relationship.
One plot idea could be Naruto discovers a hidden diary of his mother that reveals secrets about their clan. Another could be that his mother's spirit appears to guide him during a difficult mission. For example, Naruto is facing an enemy with a strange and powerful jutsu he can't figure out. His mother's spirit then gives him hints on how to counter it by using a long - forgotten Uzumaki technique.
One interesting plot idea could be exploring how Kaguya's presence affects Naruto's early life. Maybe she's in hiding and secretly guiding him, teaching him some unique jutsu that are related to her own powers. This could lead to Naruto having an even greater advantage against his enemies early on.
Another plot idea is that the baby is from a future time where Naruto's world has changed. The baby has come back in time to prevent a great disaster that will happen in the future. This would involve the baby trying to convey important messages to Naruto and his allies, but in a way that they can understand given the baby's limited communication skills.
One idea could be that she has to balance her ninja duties with motherhood. For example, she might be called on a dangerous mission while her baby is still very young. Another plot could involve her dealing with the judgment of the village. Since she's a young mother, some people might not approve, but she has to prove them wrong by being an amazing ninja and a great mother at the same time. Also, her relationship with the baby's father could be explored, whether he's still in the picture or not.
One idea could be exploring Kushina's memories and how she passed on her strength and spirit to Naruto. For example, Naruto discovers a hidden journal of Kushina's that details her training and her hopes for him. Another plot could involve Naruto time - traveling back to when Kushina was young and getting to know her in a different way, perhaps even helping her in some battles and in turn learning more about his own family's history. A third idea is that Kushina's chakra somehow manifests in Naruto during a crucial battle, giving him an unexpected boost and a connection to his mother on a deeper level during the fight.
