One possible plot could be that Kushina takes Naruto on a journey through the Hidden Leaf's history. She shows him the places that were important to her and tells him stories about the early days of the village. This helps Naruto understand his heritage better.
Maybe in the fanfic, Kushina takes Naruto to train in a special place. She imparts her unique skills and knowledge that she had, which could be different from what Naruto has learned so far. It could be a place filled with powerful chakra that enhances their training.
It could be a story where Kushina takes Naruto to meet some of her old friends or comrades. Through these meetings, Naruto gets to see a different side of his mother and the relationships she had. This also gives him new perspectives on how to build and maintain relationships within the ninja world. For example, they might visit an old hermit who was a mentor to Kushina, and from this hermit, Naruto learns some ancient ninja wisdom.
The plot could be that Kushina wants Naruto to reunite with his father. She could use her spiritual connection to Naruto to plant the idea in his mind. Naruto then embarks on a journey to find out more about his father, Minato. Along the way, he discovers secrets about the past, including how his parents really met and fell in love. This could also lead to him unlocking new powers related to his family lineage.
The relationship could develop in a way that Kushina helps Naruto deal with his inner demons. Since she has a better understanding of his situation, having been through similar things in her own life. They would have deep conversations about his loneliness growing up and how to overcome it. Kushina would use her own experiences to guide Naruto, and this would strengthen their bond.
One possible plot could be that with Minato and Kushina alive, Naruto grows up in a complete family. They could train Naruto together, passing on their unique jutsu. Maybe Minato could finally fulfill his dream of bringing long - lasting peace to the Hidden Leaf with his family by his side. And Naruto would have a different kind of confidence and growth, not having to face the loneliness he did in the original story.
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.
The plot could revolve around a mystery in the village that only Kushina, Mikoto and Naruto can solve. Maybe there are strange disappearances that are related to an ancient power that was once sealed by the Uzumaki clan and has some connection to the Uchiha. Kushina uses her knowledge of the Uzumaki history, Mikoto her understanding of the Uchiha lore, and Naruto his unique perspective as the Jinchuriki of the Nine - Tails. They have to overcome their differences and work together to save the village from this hidden threat. Along the way, they develop a deeper bond as they face various challenges.
A simple plot could be Kushina's adventures as a young ninja. She goes on missions, faces various enemies, and discovers new jutsu. For example, she could be part of a team that has to retrieve a powerful artifact from a dangerous location.
Well, the plot might involve Kushina seeing Naruto's potential right from the start and training him intensively. She could also share her own experiences of growing up as an Uzumaki, which could help Naruto better understand his heritage. And perhaps they go on special missions together where Kushina guides Naruto not just in combat but also in making tough decisions. There could be a lot of emotional moments as Kushina fills the role of both a sensei and a mother - like figure to Naruto. Also, Kushina could introduce Naruto to other Uzumaki - related things like ancient seals or special chakra control techniques that were unique to their clan.
One possible plot could be that Kushina is somehow influenced by an evil force. This force makes her believe false things about Naruto, like he's a threat to the village in the future. So, she betrays him by revealing his secrets or trying to harm him. Maybe she spreads lies about him which turns the villagers against Naruto even more.
Well, one possible plot is that Naruto is left all alone at a very young age by Kushina. This makes him an outcast even more so in the village. He might start to question his identity and purpose. He could end up having a different set of friends or allies, perhaps those who are also outcasts. And as he grows, he has to face the fact that his mother abandoned him while still trying to protect the village that didn't always accept him.
Maybe the 'plug' could be some sort of new jutsu or device in the 'Naruto' universe. The plot could involve Kushina using this 'plug' to gain new powers and protect Konoha. It could also be related to her connection with Naruto, perhaps she discovers this 'plug' has something to do with Naruto's future power or his role in the village.
