I recommend "I am the Second Young Master of the Flagwood Family" to you. The main character of this novel, Flagwood Miren, transmigrated to the Naruto World and became the second young master of the Flagwood Family. He is the same age as Kakashi. The plot of this novel also included other Naruto characters, such as Haki Shuogu, Ban, and Bo Fengshui Gate. I hope you like this fairy's recommendation. Muah ~😗
For young Naruto, his best characteristic is his unwavering determination. In fanfiction, this can be shown as he never gives up on his dreams, whether it's becoming Hokage or protecting his friends. He's also very energetic and has a big heart, always ready to befriend those who are lonely or outcast. As for young Hinata, her shyness is actually endearing. It makes her seem more real and relatable. But beneath that shyness, she has great inner strength. She's also very kind and observant, noticing things that others might miss.
Another interesting fanfiction could be set in an alternate universe where Kushina survives. Young Naruto grows up with his mother around. In this story, Kushina plays an important role in Naruto's development, teaching him not only ninja skills but also important life lessons. She also helps Naruto deal with the discrimination he faces in the village, using her own experiences as an Uzumaki in Konoha.
It could develop in a very complex way. Maybe at first, it's full of hostility as Orochimaru has his own dark motives. But as the story progresses, Naruto's positive influence might start to change Orochimaru's perspective a bit.
One common theme is the development of their relationship. It often focuses on how their feelings for each other start and grow, like Hinata's shy admiration for Naruto evolving into something deeper as they interact more. Another theme could be adventure. They might go on quests together and their relationship strengthens during these adventures.
