One idea could be a story where Naruto discovers a hidden journal of Kushina's that reveals secrets about his family and his own powers. This could lead him on a journey to understand his mother better and unlock new abilities.
A plot could involve Kushina being brought back to life somehow. Naruto and Kushina then have to work together to protect the village from a new and powerful threat. Along the way, they have heart - to - heart conversations about family, love, and the future of the Hidden Leaf.
Well, a story could be centered around Naruto having prophetic dreams about Kushina. These dreams lead him to explore more about his mother's past and in doing so, he uncovers secrets that strengthen his connection with her. They could also be in a situation where they have to enter each other's minds to fight off an evil entity that's attacking their mental states.
One plot idea could be Jiraiya training Kushina. Since he was a great ninja and had a lot of knowledge, he could pass on some unique jutsu or survival skills to her. This would not only strengthen Kushina but also create a bond between them based on mentorship.
Another plot could be a 'what - if' scenario. What if Kushina didn't die? Naruto grows up with his mother around. The story could explore how Kushina helps Naruto train, not just in ninjutsu but also in understanding his Uzumaki heritage. It could also show how their relationship affects Naruto's relationships with others in the village, like how he might be more confident with Kushina's support.
They could go on a mission together in the fan fiction. During this mission, they face challenges that force them to rely on each other and understand each other's strengths and weaknesses. For example, Kushina might be strong in sealing jutsu and Naruto in his Rasengan techniques, and they combine their skills to defeat the enemy.
A great plot could be that the OC Uzumaki is a healer. Naruto gets seriously injured in a battle, and she uses her Uzumaki healing abilities to save him. As a result, they become closer. Then, they find out that there is a conspiracy to eliminate all Uzumaki descendants. So they work together, using their combined skills and the power of the Uzumaki heritage to fight against this conspiracy.
One plot idea could be that Karin discovers a hidden Uzumaki power and Naruto helps her master it. They train together and form a strong bond during the process.
One idea could be a time - travel plot where Naruto, Naruko (presumably a female version of Naruto), and Kushina are all brought together in a different era. They could team up to face a new and powerful enemy that threatens the very existence of their clan or the village. Another could be a story where they are all in a training session together, with Kushina teaching the two younger ones some of her unique ninja techniques.
One interesting plot could be that 'dark kushina' initially tries to manipulate Naruto for her own goals but gradually develops real feelings for him as she gets to know him better. Another could be that they are forced to work together to save the Hidden Leaf Village from a powerful enemy.
Perhaps in this fanfiction, Naruto discovers a hidden ability that was passed down from Kushina. They go on a journey together to learn more about this power and how to control it. This would involve a lot of training sessions and some heart - to - heart conversations between mother and son.
Maybe in the fanfiction, Naruto discovers a hidden part of his chakra that has a special link to young Kushina. This link allows them to communicate telepathically. They then use this connection to share secrets about their respective lives, and Naruto learns more about his mother's past and her dreams when she was young.
