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 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.
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 a Naruto x fem wolf goddess x fem kyuubi fanfiction, the fem wolf goddess could represent a more spiritual or wild aspect. She might introduce Naruto to a different side of the ninja world, one that is more in tune with the natural order. The fem kyuubi, on the other hand, could have a more fiery and powerful personality. The story could revolve around Naruto trying to balance the influence of both characters while also dealing with his own growth as a ninja.
One possible plot could be that the female werewolf is an outcast in her own world. Naruto, with his kind heart, befriends her. Meanwhile, the fem Kyuubi has a connection to Naruto due to the Kyuubi within him. They all come together when a common enemy threatens the Hidden Leaf. The werewolf could use her unique abilities, like enhanced strength and speed, to help Naruto in battles, while the fem Kyuubi might offer her own brand of power, perhaps related to chakra manipulation. As they fight side by side, a deep bond forms between Naruto and the two female characters.
A prevalent theme is also acceptance. Naruto has to accept these two unique entities into his life, and they in turn have to accept him and each other. It's about how different beings from different backgrounds can come together. And there's often the theme of adventure as they go on various quests or face threats in the Naruto world.
