In a fanfiction, 17 - year - old Naruto could find a hidden scroll that was left by Kushina. As he deciphers it, he uncovers secrets about his Uzumaki heritage and special powers that were passed down from her. This discovery could lead to Naruto becoming even more powerful and respected in the ninja world, while also feeling a closer connection to his mother who he never really got to know in person.
One possible fanfiction could be about Naruto at 17 finally getting to know more about his mother Kushina through some kind of time - travel or spiritual encounter. Maybe he discovers some hidden jutsu she created and uses it to defeat a new enemy in the village.
A fanfiction might revolve around 17 - year - old Naruto having dreams where he meets Kushina. In these dreams, she teaches him valuable life lessons and ninja techniques that he then uses in his real - life battles. It could also show how Naruto's understanding of his family and his place in the village deepens through these interactions with his mother, even if it's in a dream - like state.
Perhaps Kushina's spirit has been watching over Naruto all this time. When Naruto turns 17, he becomes aware of her presence. She then guides him to find a long - lost Uzumaki artifact. Along the way, Naruto has to face many challenges and his bond with his mother grows stronger as he learns more about her past and her hopes for him.
Another aspect could be that the fanfiction delves into how Kushina's presence affects Naruto's relationships with others. For instance, his relationship with Sasuke could be different. With a strong maternal figure in his life, Naruto might be more stable emotionally and be able to approach Sasuke in a more understanding way, which could potentially change the whole dynamic of their rivalry and friendship.
One possible fanfiction could be about Kushina finding Naruto in a situation where he's lost in a forest. Maybe she uses her unique chakra sensing abilities to track him down. It could be a heartwarming story of a mother reuniting with her son.
In some fanfictions, the authors might take creative liberties and create alternate universes where Naruto and Kushina interact in different scenarios. For example, they could be on a joint mission together, and through that, we see their personalities shine. Kushina's fiery nature and Naruto's determination would make for an interesting dynamic.
In certain fanfic concepts, Naruto could have found a special relic or artifact. This relic might have the power to reverse death. Since Naruto is always on adventures and exploring different places, he might stumble upon such an item and use it to revive Kushina. It could also be related to the Uzumaki clan's secrets that he uncovers which enables him to bring his mother back.
Perhaps Naruto finds a way to travel back in time and prevent Kushina's death in the first place. He could use his Sage Mode or some other special ability to manipulate time. And then, by changing the past, he effectively'revives' her in the present. In the Naruto universe, there are all kinds of crazy powers, so time - travel isn't completely out of the question.
One possible reason could be for Naruto's protection. Maybe she thought by banishing him from a certain place or situation, she could keep him away from a hidden danger that she knew about. For example, there might be a powerful enemy targeting Naruto specifically, and she believed that by making him leave, he would be harder to find.
Minato could be a common character. Since he was Kushina's husband in the original story, his presence might add some interesting dynamics to the harem scenario. Another could be Jiraiya. His connection to Naruto and his reputation as a bit of a ladies' man could make for an interesting addition to the story.
In some fanfictions, Kushina was sealed into Naruto through a complex jutsu. It might be a modified version of the sealing jutsu used to seal the Nine - Tails. The process could involve special incantations and chakra manipulations.
One common plot is Kushina finding Naruto in a different time or dimension. For example, she might end up in the future where Naruto has grown up and she gets to see the kind of person he has become. It's an emotional and interesting concept as she gets to witness all his achievements and the challenges he has overcome.
