For Naruto, you can develop his character by having him face new challenges related to his relationship with Narumi and Naruko. For example, he might struggle with how to balance his friendship with both of them. Narumi could be developed by giving her a backstory that ties into the Naruto universe in a unique way, like she has a family connection to an old ninja clan. And for Naruko, you can explore her more feminine side in contrast to Naruto's more brash nature, especially when it comes to her interactions with Narumi.
For Naruto, you could show his growth in terms of his leadership skills when he's with Naruko and Kushina. He could learn to be more patient and understanding, especially when Naruko might have a different approach to things. For Naruko, her character could be developed by showing her struggle to be recognized in a world where Naruto already has a reputation. Kushina could be developed by exploring her motherly side more deeply, as she interacts with both Naruto and Naruko.
It might develop through shared battles. As Naruto uses his godlike powers in fights, Naruko sees his strength and determination, and she is drawn to him more.
Sakura could be a potential character. She has a long - standing relationship with Naruto, and in this harem scenario, she might be jealous of Naruko at first but then come to accept the situation. Hinata could also be part of it. Given her love for Naruto, she would be an interesting addition to the harem, adding a shy and gentle dynamic.
They can start by simply spending time together. For instance, going on missions side by side. This allows them to get to know each other's fighting styles and personalities better. As they face challenges during these missions, they start to rely on each other more.
The relationship could develop through shared experiences. For instance, they might go on a mission together where they have to rely on each other to survive. Naruto could see the Naruko clone's determination and courage, and she could see his kind heart. This mutual admiration could lead to a deeper emotional bond. Another way is through Naruto teaching the Naruko clone about things she doesn't understand, like the history of the village or certain jutsu. This teacher - student dynamic can slowly transform into a romantic relationship as they get closer.
In the fanfiction, Naruto and Naruko could start off as strangers who are brought together by the mystery of their Uzumaki bloodline. They might be curious about each other's abilities and start to train together. During this process, they would have small arguments because of their different ways of using the bloodline powers. However, these arguments would actually make them understand each other better. As time passes, they become closer and closer, and the relationship develops from acquaintances to friends, and finally, lovers. Their Uzumaki bloodline would be like a thread that ties them together throughout the development of their relationship.
At first, Naruto might be completely oblivious to the yandere Fem Sasuke's feelings. But as she starts to show her possessiveness more openly, he'll have to face it. This could lead to some arguments between them. However, over time, Naruto could start to see the good in her. He might realize that her love, although extreme, is genuine. And so, they could start to build a more trusting relationship. For example, she could open up to him about her past and why she's so protective, which would bring them closer.
One common theme is the extreme nature of the yandere's love. It's often possessive and can lead to some intense and sometimes dangerous situations for Naruto. Another theme is the struggle between Naruto's own values and the yandere's demands. For example, Naruto might value friendship and freedom, while the yandere wants him all to themselves.
One common theme is obsession. The yandere character is often overly obsessed with Naruto. For example, they might follow him everywhere or try to keep him away from other people. Another theme is possessiveness. They see Naruto as their own and get jealous easily.
