One reason could be the realisation of the strong bond they could have had. Kushina might understand in the fanfiction that Naruto has been through so much alone, and she missed out on being there for him. She may regret not being able to protect him from the hardships and bullying he faced as a child.
Kushina would most likely experience deep remorse. Remorse for not being there for Naruto when he needed a mother. There could also be a sense of longing in her, longing to be part of Naruto's life and to make up for all the lost time. And of course, she might be filled with self - loathing for her past actions.
The overall mood of the story can shift with Kushina's regret. It can go from a more lonely and self - discovery journey for Naruto to a story about family reconciliation. This regret can be a catalyst for bringing in more themes of forgiveness, redemption, and the power of family. It can also attract readers who are interested in complex family dynamics and emotional character arcs within the Naruto fanfiction world.
One possible reason could be that she later realizes Naruto's true nature and potential. Maybe she sees how strong and kind - hearted he is despite the hardships he faced. She might regret not being there for him during his growing - up years when he needed a mother figure.
One reason could be the motherly love. Kushina always loved Naruto deep down. Leaving him means missing out on his growth and important moments in his life. Another reason might be realizing the hardships Naruto faced without her presence. She probably feels guilty for not being there to protect him from the loneliness and the many challenges he had to endure in the village.
It might show Kushina trying to make amends. She could start by reaching out to Naruto in small ways, like leaving him little gifts or messages. Naruto, at first, might be skeptical but as he sees her sincerity, they start to build a relationship.
Well, it could lead to her trying to make amends. Maybe she starts to secretly protect Naruto from the shadows, which adds a layer of mystery to the story. Her regret might also cause her to interfere in Naruto's relationships, like with his friends or mentors, in an attempt to make up for her past actions.
Well, in a typical scenario for this kind of fanfic, Kushina might have left Naruto due to some difficult situation or misinformation. When she discovers Naruto has become 'godlike', perhaps with extraordinary powers and a great reputation. Her regret could lead to her attempting to reconnect with Naruto. She may face obstacles like Naruto's initial resentment or the complex political and social situations in the Naruto world that prevent a smooth reunion.
Well, when the Sharingan is neglected in fanfiction, it can lead to a less diverse range of powers and abilities being represented. The Sharingan has unique abilities like predicting movements and copying jutsu, and without it, stories may lack that kind of strategic and combat - related depth. Also, it can make the Uchiha clan seem less important in the fan - created Naruto universe, which goes against the significance they have in the original series.
Maybe it's because she sees Naruto's strength and how he has overcome so many difficulties despite her absence. She realizes that if she had been there, she could have made his journey easier. Also, she might regret not being able to watch Naruto grow up, miss his first steps, first words, and all those precious moments that a mother should be a part of.
