In this fanfiction, Naruto might have some new, unique abilities or powers that are specific to this story. He could use these to his advantage. For example, he might have a special connection to Kushina that allows him to sense her location precisely. He could then use his shadow clone jutsu to create multiple copies of himself to distract the Kumo forces while he rescues Kushina. Also, his training with Jiraiya could have given him some special techniques that are useful in this situation.
Well, in some versions, Naruto might use his powerful jutsu. Maybe he uses his Rasengan to fight off the Kumo ninjas who are after Kushina. He could also use his speed and agility to outmaneuver them and get Kushina to safety.
One challenge could be the powerful ninja from Kumo. They are known for their strength and combat skills. Naruto would have to face them in order to rescue Kushina.
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.
Well, in many fanfics, Naruto might become godlike through intense training, perhaps unlocking some super - rare chakra or some ancient power. Maybe he has a special encounter with a powerful being who bestows him with extraordinary abilities.
She could use her Uzumaki chakra chains to break through any barriers or enemies in their way. Maybe she also has some secret teleportation jutsu that she uses to quickly get away with Naruto.
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 many such fanfictions, Gaara might use his sand powers. He could sense Naruto is in danger through his connection to the sand or his own instincts. Then, he'd quickly move in, using his sand to shield Naruto from any attacks by the Akatsuki members, like blocking their jutsu with his powerful sand barriers.
Perhaps in this fanfiction, Naruto has some sort of special power or transformation that he unlocks just in time to face Orochimaru. It could be related to his Nine - Tails chakra in a new and unique way. He uses this power to break through Orochimaru's defenses and save Hiruzen. Naruto might also use his knowledge of Orochimaru's weaknesses that he has learned either from Jiraiya or from his own past encounters with Orochimaru's minions.
In certain fanfiction concepts, Naruto might make a deal with some sort of spiritual entity. He sacrifices something of his own, like a part of his power or his future, in order to bring Kushina and Minato back. Or he could have harnessed the power of the tailed beasts in a new and unique way. The tailed beasts are extremely powerful, and if he could combine their power with his own in a specific way, it might be enough to revive his parents.
Perhaps Naruto feels that Kushina is being overprotective. He wants to prove his independence and go on his own adventures without her constant supervision, so he decides to run away.
Kushina would be extremely worried. She would rush to Naruto's side immediately and start using her medical knowledge or any available resources to help him get better.
