Maybe Kushina's spirit somehow gets linked to Sakura. Kushina then starts to guide Sakura in her ninja training, sharing her own experiences and unique jutsu. This mentorship could turn into a deep friendship, and they could face various challenges together in the shinobi world, such as dealing with a new threat to the village while also exploring their relationship.
A possible plot could be set in an alternate universe where Kushina didn't die. Sakura, being a skilled medic - ninja, is assigned to take care of Kushina after an injury. During the recovery process, they start to talk and learn about each other. Sakura is intrigued by Kushina's strength and Kushina is impressed by Sakura's determination. This leads to a relationship that grows over time, with them supporting each other in different aspects of their lives in the village.
One plot idea could be that Sakura discovers some long - lost scrolls left by Kushina. Through reading them, she starts to have dreams about Kushina and gradually forms a connection. As she delves deeper into Kushina's past, she realizes they have more in common than she thought, and a bond forms between them.
One possible plot could be that Kushina has some misunderstanding about Sakura. Maybe she thinks Sakura is being disrespectful to Naruto in some way, so she punches her to teach her a lesson. Then, Sakura tries to figure out why Kushina is so angry and they start a series of interactions that eventually lead to them resolving their differences.
One possible plot idea could be that Naruto discovers he has a connection to the Dragon Sage power through Kushina's heritage. Maybe Kushina was secretly a part of a long - lost Dragon Sage clan, and this power is passed on to Naruto. He then has to learn to control this new power while facing off against new enemies who are also after the Dragon Sage power.
One idea could be a story where Kushina and Sakura team up on a mission in a new and dangerous land. They have to rely on each other's unique skills, like Kushina's powerful chakra and Sakura's medical ninjutsu and combat abilities. Along the way, they face various challenges that strengthen their bond as friends and comrades.
Perhaps a story where Kushina is resurrected somehow and has to adapt to the new world that Sakura is a part of. They could start off as strangers but gradually become friends as Kushina learns about the modern ninja techniques and Sakura learns from Kushina's old - fashioned but effective ninja wisdom.
A plot where Kushina is revived and she takes Sakura under her wing as a sort of mother - figure or mentor. They then both work together to support Naruto in his Hokage duties. This would focus on the strong female - female relationship between Kushina and Sakura and their combined influence on Naruto's life, without any lemon elements.
It could be a story where the 'narutoslut' character looks up to Kushina as a role model and they form an unlikely friendship. Maybe the 'narutoslut' is from a different part of the Naruto world and through their encounters with Kushina, they learn about her past and her relationship with Naruto.
One possible plot could be that Natsumi is a new character who befriends Naruto. Through Naruto, she gets to know about Kushina. They then form a unique bond where they all support each other in Naruto's journey to become Hokage. Natsumi might have some special skills that complement Naruto's and Kushina's abilities.
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.
One idea could be a time - travel fanfiction where Sakura somehow travels back in time and meets Kushina. Kushina could mistake Sakura for a future friend of Naruto's and start to train her in some of her unique Uzumaki techniques. Meanwhile, Naruto is left wondering how Sakura disappeared and tries to find a way to bring her back.
One possible plot could be that Sakura somehow travels back in time and meets Kushina. Kushina, being Naruto's mother, could see some of Naruto in Sakura and they could bond over that. Maybe Kushina would teach Sakura some of her unique ninja techniques or give her advice on how to deal with difficult situations in the ninja world.
