She might start by using her knowledge of Naruto's past. Since she is his mother, she knows things about his early life that no one else does. She could use these memories to create an emotional connection with him. Maybe she'll show up in his dreams first, like a hazy memory, and then gradually reveal herself in the real world.
In the fanfiction, Kushina may plan to get Naruto back through her chakra. Since they are related, their chakra might have a special connection. She could use this connection to reach out to Naruto on a spiritual level. Once she has his attention, she could start sharing her story with him, how she has always loved him and was separated from him against her will. She may also try to get to know Naruto's friends and allies. By being a part of his social circle, she can be closer to him and eventually make him accept her as his mother.
Well, she might face the challenge of Naruto's trust. Since she has been absent for so long, Naruto may not trust her immediately. Also, the ninja world is full of threats. There could be enemies who try to stop her from getting close to Naruto. And Naruto has his own sense of identity which is deeply rooted in being an orphan and a self - made ninja. Kushina has to respect that and find a way to fit into his life without disrupting it completely.
Kushina could also seek the help of other powerful shinobi. For instance, she might ask Minato for assistance. Since Minato was Naruto's father and also a very skilled ninja, together they could come up with a plan to reunite with Naruto. Maybe they would use some sort of space - time ninjutsu to get closer to him.
Maybe they enlist the help of other powerful ninjas. For instance, they could ask Tsunade for medical support in case Naruto is injured. They could also get intel from Shikamaru, who is known for his intelligence. By gathering a team of reliable and strong ninjas, they increase their chances of getting Naruto back successfully.
In certain fanfic ideas, Naruto could have made a deal with some sort of otherworldly being. He might have sacrificed something of great value, like a part of his own chakra or a future ability, in exchange for Kushina's life. Another possibility is that he finds a way to reverse the very nature of death by using some unique properties of the tailed beasts' chakra that he has access to.
Well, in some fanfictions, Minato might use his powerful jutsu to break through the barriers between the living and the dead and directly reach Naruto. He could also try to influence the people around Naruto to bring him closer to where Minato is, like using his spirit to communicate with Naruto's friends and convince them to help.
One consequence could be that it messes with the natural balance of the ninja world. Maybe the cycle of life and death is disrupted, and this causes some strange phenomena to occur, like abnormal weather or chakra imbalances.
Naruto's reaction could be complex. On one hand, he would be extremely excited. But on the other hand, he would be worried about the consequences. He has learned about the balance of the ninja world and might be afraid that bringing Kushina back could have negative impacts. However, his love for his mother would probably overpower those concerns in the end, and he would still strive to make her return a reality.
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.
The scene might serve as a symbol of family and support. In a fanfiction, the plot often revolves around the characters' relationships. This moment of Kushina massaging Naruto back can strengthen the family - centered aspect of the plot. It can show that Naruto has someone in his corner, someone who cares deeply for him. And this support can then be a driving force for Naruto in other parts of the plot, like when he has to make difficult decisions or fight against powerful foes.
Annabeth could show her determination by going out of her way to be in the same places as Percy. She'll be wherever he is, whether it's at his favorite spots or events he attends. And she'll always be there with a kind word or a helpful gesture, constantly reminding him of their connection. Also, she might face any danger or difficulty that comes her way while trying to get close to him again, showing that she's willing to do whatever it takes.
