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.
Yes, there are likely some non - adult fanfictions out there. Some might focus on their relationships in a more family - oriented or friendly way. For example, they could be depicted in a story where they train together, share their dreams and support each other in achieving their goals in the ninja world.
One idea could be a time - travel plot where Naruto, Naruko (presumably a female version of Naruto), and Kushina are all brought together in a different era. They could team up to face a new and powerful enemy that threatens the very existence of their clan or the village. Another could be a story where they are all in a training session together, with Kushina teaching the two younger ones some of her unique ninja techniques.
One common theme is mentorship. Kushina could be seen as a mentor to Naruko, guiding her in her ninja journey. Another theme is family. Since Kushina is Naruto's mother, there can be a family - like connection explored between her and Naruko.
One popular 'naruko x kushina fanfiction' is 'A Mother's Love'. It beautifully portrays their relationship in a heartwarming way. It shows how Kushina's strong spirit influences Naruko as she grows up.
One common theme is family. Since they are mother and daughter, stories often focus on how they build or strengthen their family bond. Another theme is legacy. Kushina's legacy and how Naruko lives up to it or carves her own path while still being influenced by her mother.
I'm not sure if there is such a fanfiction specifically. Fanfiction websites have a vast range of works, but 'lemon' fanfictions often contain inappropriate content. It's better to focus on non - explicit fanfictions that explore the relationships and stories in a more positive and appropriate way.
How about a story where Naruto, Kushina and Naruko are all transported to a different dimension? In this new world, they have to rely on each other to survive and find a way back home. Along the way, they face various challenges that test their relationships and their individual strengths.
Often, there might be themes related to power and growth. Naruko with her 'futa' characteristics might have different powers or abilities, and how she and Kushina interact in terms of power dynamics can be a theme. Another theme could be the discovery of self - identity, especially for Naruko, as the 'futa' aspect may add an extra layer to her character development and how Kushina influences or is influenced by it.
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.
