In the 'kushina raises naruto fanfic', there might be a plotline where Kushina trains Naruto to master his chakra control better. Since she has great control over her own chakra, she could pass on her knowledge and techniques. This would not only make Naruto stronger but also show a different side of his growth compared to the canon story.
One possible plotline could be Kushina teaching Naruto some of her unique Uzumaki clan jutsus early on. This would give Naruto an edge in battles and also a deeper connection to his heritage.
One possible plotline could be Minato teaching Naruto special jutsu early on. Since Minato was a very powerful ninja, he could pass on his knowledge of the Flying Thunder God Technique to Naruto at a young age, which would make Naruto even more formidable in battles against early foes.
One possible plotline could be Kakashi teaching Naruto some of his unique ninja techniques in more detail, like how to better use the Rasengan. Another could be Kakashi helping Naruto deal with his inner demons regarding being an orphan and the Nine - Tails. Maybe there's a plotline where Kakashi trains Naruto to be a more strategic fighter, not just relying on brute force.
A plotline might involve Naruto traveling back in time and meeting Kushina when she was young. They could start as friends and gradually fall in love. Or perhaps there's a prophecy that links them together, and they have to fulfill it, which leads to their mating. There could also be a situation where a powerful enemy forces them to work closely together, and that closeness turns into a deeper relationship.
One interesting plotline could be Kushina's influence on Naruto's chakra control. Since she was a jinchuriki too, fanfics might explore how she could have taught Naruto some unique techniques related to the Nine - Tails' chakra if she had been alive longer.
One interesting plotline could be Naruto finding a hidden journal of Kushina's that reveals secrets about their family or the village. Another is Kushina guiding Naruto in his dreams to master a new jutsu.
One possible plotline could be that Mikoto discovers Naruto at a young age and decides to take him in secretly. She then starts training Naruto in her own unique ways, perhaps combining Uchiha techniques with Naruto's natural abilities.
One possible plotline could be Obito teaching Naruto some unique jutsu that he learned during his time in Akatsuki. For example, he might show Naruto how to use certain space - time ninjutsu in a different way. Another could be Obito helping Naruto understand the Uchiha clan better, given his own Uchiha heritage.
Perhaps the fox starts to develop human - like emotions and behaviors under Naruto's care. This could lead to some really heartwarming moments as Naruto helps the fox understand things like friendship and loyalty. They could then form an even stronger bond that surprises everyone in the village.
The fanfic might differ in terms of Naruto's training. With Kushina around, his training could be more focused on Uzumaki - specific techniques. In the original, he learns from various people like Jiraiya. Here, Kushina could introduce him to different aspects of the Uzumaki clan's power, which could lead to a completely different set of skills and battle strategies for Naruto.
One possible plotline could be that Kushina is somehow mind - controlled or influenced by an evil force to harm Naruto. Maybe she's under a powerful genjutsu that makes her see Naruto as a threat to the village instead of her son.
