Well, the story could start with Naruto and Fem Kyuubi being transferred to the High School DxD school. Naruto might struggle to adapt to the different rules and social hierarchy there. The Fem Kyuubi, on the other hand, could use her charm and wits to navigate through the new environment. Their relationship could evolve as they face challenges together, like dealing with the various factions in the school.
His role could be that of a protector. Given his nature of protecting his friends in the Naruto series, he would likely do the same in the High School DxD world. He could protect Fem Kyuubi from those who might want to take advantage of her power. Also, he could be a bridge between the different species in the school, using his understanding of different types of people from his own world.
If Naruto had Kyuubi's power in the High School DxD universe, things would be chaotic at first. His presence would be a shock to the different factions. The devils would likely try to either recruit him or eliminate him. But Naruto, with his strong will and Kyuubi's power, could form new alliances. He could teach the students at the school some of his ninja ways and in turn learn about the magic and powers in that world. His Kyuubi - enhanced abilities would make him a formidable opponent in the Rating Games.
One great fem Naruto x fem Kyuubi fanfiction could be one that focuses on their unique bond. It might explore how they interact in a world where Naruto is female and the Kyuubi also takes a female form. For example, it could show them teaming up against common enemies and how their combined powers are different from the original story.
In a Naruto and High School DxD fanfiction, there could be a scenario where the protagonists of both stories meet in a neutral dimension. Issei from High School DxD might be intrigued by Naruto's ninja skills and determination. Naruto, in turn, could be curious about Issei's Sacred Gear. They could start training together, sharing their knowledge and skills, and ultimately have to face a common enemy that threatens both their worlds.
In this type of fanfiction, one can expect a lot of creative interpretations. Naruto's 'godlike' state could mean he has new abilities that he uses to protect the fem kyuubi. Their relationship might not be a typical one. Maybe they start off as unlikely allies and gradually form a deep bond. The story could also delve into the lore of the Naruto universe, like how the fem kyuubi's nature affects their relationship.
The plot should be engaging. It could involve a new threat to the ninja world that only fem Naruto and fem Kyuubi can stop together. This could lead to a lot of action - packed scenes and also some really touching moments between them as they rely on each other. A good fanfiction might also explore their backstories in this new context, like how fem Naruto came to terms with having the Kyuubi inside her as a female.
One possible fanfiction could be about Naruto characters attending the school in High School DxD. For example, Naruto's positive and determined attitude might clash with the more complex social and power dynamics in the DxD world. He could make new friends or even rivals among the devils, angels, and fallen angels.
One possible fanfiction could be about Naruto characters somehow ending up in the world of High School DxD. Maybe Naruto's skills in combat and his determination would make him a formidable opponent in the battles that often occur in the High School DxD universe. He could form interesting alliances or rivalries with the characters there.
A fanfiction could focus on Naruto's training regime influencing the characters in High School DxD. His intense physical and mental training could inspire the students at the school. They might start incorporating some of his training methods, like running up trees or on water, to improve their own strength. And Naruto could also learn from their magic-based training and combine it with his chakra control for new and powerful techniques.
