The plot could start with the female Harry Potter stumbling upon Naruto as a young orphan in her travels. She feels a connection to him, having lost her own parents. So, she takes him back to her world. As Naruto grows up, he has to deal with the prejudice some wizards have towards his ninja ways, just like he faced prejudice in his own world. But with Harry's guidance, he learns to prove himself. He could also introduce the wizarding world to things like ramen, which would become a huge hit among the students at Hogwarts.
Well, in this fanfiction, the female Harry Potter might raise Naruto in a world that's a blend of the Harry Potter and Naruto universes. She'd introduce him to Hogwarts - like how could he not be curious about a huge castle full of magic? And Naruto, being the eager learner he is, would soak up all the knowledge about magic, potions, and spells. He might even try to combine his chakra control with magic. Maybe he'd create a new kind of jutsu using a spell as a base.
One possible plot could be that the female Harry Potter, using her magic skills, finds Naruto in a different dimension or perhaps when she accidentally travels to the Naruto universe. She decides to take him under her wing. She could teach him some basic magic concepts, which Naruto might adapt in his own unique way for his ninja skills. For example, he could use the idea of transfiguration to change the appearance of his shadow clones in a more complex way.
In such a fanfiction, Harry might raise Naruto in a way that combines the values of both the wizarding world and the ninja world. He could introduce Naruto to the concept of different magical creatures, which Naruto could then try to incorporate into his ninja training. Maybe Naruto would learn how to communicate with magical animals like Hedwig, and use that knowledge to better understand the summons in his own world. Also, Harry could help Naruto with his studies, which would be a huge change for Naruto who wasn't that good at traditional schoolwork at first. This would not only make Naruto more well - rounded but also give him an edge in the ninja world with his new - found knowledge.
In such a fanfiction, perhaps Harry Potter feels a sense of duty to raise Delphini despite her being Voldemort's daughter. He might see her as a chance to break the cycle of dark magic. He could raise her with the values of love and friendship, trying to turn her into a force for good in the wizarding world.
Well, perhaps the plot could involve Harry having to fend for himself from a very young age in the wizarding world. He might have to figure out magic on his own, without much guidance from adults. Maybe he starts exploring the secrets of Hogwarts by himself earlier than in the original story, leading to all sorts of unexpected adventures.
One possibility could be that Harry, with his knowledge of magic and experience in fighting dark forces, takes Tsuna under his wing in the magical world. He could teach Tsuna about different spells and how to handle magical creatures, which would be a new and exciting experience for Tsuna who is used to his own world in 'Katekyo Hitman Reborn!'.
Well, in this fanfiction, Kakashi might introduce Harry to the concept of chakra. Since Harry has magic, Kakashi could find a way to combine the two powers. Maybe Harry would learn to use chakra to enhance his spell - casting speed or accuracy. And Kakashi would also help Harry deal with his emotional traumas, like the death of his parents, in a more ninja - like, stoic way.
Well, in this fanfiction, Deadpool might raise Harry Potter in a world where the two universes collide. Deadpool could introduce Harry to the concept of fourth - wall breaking, which would be really strange for Harry. He could also take Harry on adventures that involve both the wizarding world and Deadpool's own crazy world filled with mercenaries and mutants, leading to some really unique and comical situations.
Maybe Harry starts raising chickens because he wants to have a normal, non - magical hobby. He finds some regular Muggle - like chickens in a nearby village. As he raises them, he realizes that they have an uncanny ability to sense dark magic. So, they become like an early warning system for any approaching danger at Hogwarts. This could lead to all sorts of adventures where Harry has to protect his chickens from dark wizards who want to use their power for evil.
One possibility is that Harry discovers a long - lost sister and takes on the role of a protector. He might teach her magic in secret, away from the prying eyes of the wizarding world authorities. Maybe they live in a hidden cottage and he passes on the skills he learned at Hogwarts to her.
In the fanfiction, Harry might raise his cousin in an attempt to break the cycle of animosity that has always been between them. He could show his cousin a different side of life, full of magic and wonder. Harry could also protect his cousin from the dark forces that are always lurking in the wizarding world, and in the process, his cousin could become a valuable ally to Harry.
One possible plot twist could be that Amelia Bones discovers some long - hidden secret about Harry's family that changes his entire perception of himself. Maybe she uncovers a connection between the Bones family and the Potters that was lost over time.
