One possibility is that Fem Naruto, being a strong - willed character, is intrigued by Ophis' power. Maybe she first encounters Ophis during a mission or some sort of interdimensional event. She could start to study Ophis' abilities and gradually become a fan in the sense of admiring her power. For example, Fem Naruto might see how Ophis can manipulate energy in ways she has never seen before and be inspired to learn more about that type of power, which could lead to her trying to incorporate some of those concepts into her own jutsu development.
The plot could involve Fem Naruto being in a situation where she is in need of power or knowledge that she believes Ophis can provide. She might be facing a new and extremely powerful enemy that her normal ninja skills can't handle. So, she seeks out Ophis. As she spends time with Ophis, she discovers not only power but also a different way of looking at the world. Ophis' non -chalant attitude towards things that Naruto finds difficult, like the balance of power and the concept of good and evil, makes Fem Naruto admire her. This admiration then turns into being a fan, and she starts to emulate some of Ophis' behaviors and ideas.
Well, it could be about Fem Naruto being in the Highschool DxD world and being a huge fan of Ophis. Maybe she tries to seek Ophis out for power or knowledge. For example, Fem Naruto, with her ninja skills, could navigate the complex world of Highschool DxD, which is full of devils, angels and other supernatural beings. She might see Ophis as a source of strength that could help her achieve her goals, whatever they may be in this new and strange world.
Well, one possibility is that it could explore how the fem Kyuubi's new role as Naruto's mother would change Naruto's upbringing. Maybe she would use her powerful chakra to protect Naruto in ways that Kushina couldn't. For example, she could teach Naruto some unique jutsu that are related to her own nature as the Kyuubi. Also, it could show how the relationship between Naruto and the other villagers would be different. Since the Kyuubi is now in a maternal role, perhaps the villagers would be more accepting of Naruto earlier on.
Well, the plot could involve her adapting to the ninja world. Maybe she'd bring some of her magic knowledge from the Harry Potter universe, like using spells in a new way to mimic ninja techniques. She could also have a special bond with Naruto, being his sister, and help him in his journey to become Hokage, like using her intelligence to outwit enemies.
The plot could involve Naruto somehow getting cursed by Slenderman. This curse starts to affect his ninja abilities, like his chakra control. As he tries to figure out what's wrong, he discovers the connection to Slenderman. He then has to journey into the dark and mysterious places where Slenderman lurks to break the curse. Along the way, he might meet some of Slenderman's minions and have to fight them using his unique jutsu.
Well, in a Naruto becomes a hollow fanfiction, perhaps the chakra system in Naruto gets corrupted and turns him into a hollow. His appearance would change to something more menacing. He might start to crave spiritual energy instead of normal food. His relationships with other characters would be on edge. For example, his bond with his teacher Kakashi would be tested as Kakashi tries to figure out how to reverse the transformation or at least help Naruto co - exist with his new hollow self.
In a Naruto - becomes - a - teacher fanfiction, Naruto could focus on teaching his students about the value of friendship and teamwork. He might organize team - building exercises that are actually dangerous ninja missions. His students would learn to rely on each other, just as he did with his own team. He could also share stories about his adventures with the Akatsuki, making sure his students understand the threats that still exist in the ninja world.
In a Naruto becomes a hermit fanfiction, he could be on a journey to find a deeper meaning to his existence. He might abandon his fame and status. Living as a hermit, he'd have to fend for himself, which would make him stronger in a different way. He could start to understand the true essence of chakra in a more spiritual sense, away from the battles and politics of the shinobi villages.
The plot could also involve Naruto being transported to the world of Sparda. There, he has to learn the ways of that world to survive. He might meet characters similar to those in his own world, but with different abilities. And he could form new alliances, like teaming up with demons who oppose the main evil forces in the Sparda universe.
One possibility could be that Naruto discovers a new side of Himawari. Maybe she shows an unexpected talent for ninjutsu that Naruto is really impressed by. This could lead to Naruto becoming her biggest supporter and fan, constantly cheering her on during her training sessions.
Well, it could be that Naruto discovers the tales of Gilgamesh's power and heroics. Maybe he starts to idolize Gilgamesh's confidence and his unwavering belief in his own supremacy.
