A possible plot point is that the Hogwarts founders had some connection to kitsune. Maybe they learned some of their magic from kitsune or made a pact with them long ago. This connection could be revealed to Harry through some ancient artifacts or hidden chambers. Harry could then start to explore this link and find that it gives him access to a different kind of magic. Another interesting plot point could be that the Ministry of Magic is suspicious of Harry's newfound kitsune - like abilities and tries to restrict him. This would create a conflict between Harry and the Ministry, similar to the conflicts in the original series, but with a new twist due to the kitsune element. Also, there could be a kitsune character who acts as a mentor to Harry, teaching him about his new powers and the history of kitsune in the wizarding world.
Well, perhaps the Sorting Hat detects some kitsune - like qualities in Harry and is unsure whether to put him in Gryffindor or create a new house for him. This could start a whole new debate within Hogwarts. Also, the idea of kitsune illusions could play a role. Harry could use kitsune - inspired illusions to deceive his enemies, like creating false images of himself or his friends to mislead Death Eaters. And what if the Dementors are actually related to some dark aspect of kitsune lore? Harry would then have to use his newfound knowledge of kitsune magic to combat them in a different way than just using the Patronus charm.
One plot idea could be that a Kitsune disguises itself as a student at Hogwarts to learn more about human magic. It could get involved in Harry's adventures and use its Kitsune abilities, like shape - shifting or illusion - casting, to help or sometimes cause trouble. Another idea is that a Kitsune is a guardian spirit of an ancient magical place near Hogwarts, and Harry discovers it during one of his explorations. The Kitsune then becomes an ally or a guide for Harry in uncovering secrets about the wizarding world.
One idea could be that the female kitsune uses her shape - shifting abilities to help Harry Potter in his fight against Voldemort. For example, she could transform into a bird to spy on the Death Eaters. Another plot could involve the kitsune's magical powers being a key to unlocking an ancient magic that can defeat the Dark Lord. She might also have a connection to the magical creatures in the Harry Potter world, like helping Hagrid with some of his more dangerous creatures.
Maybe Harry discovers a hidden connection between his family and ancient dragons. This could lead him on a journey to uncover the secrets of his past and the power that the connection to the dragons might hold. He could then use this new - found knowledge to defeat Voldemort in a more unique way than in the original story. For instance, by using dragon - inspired magic or enlisting the help of friendly ancient dragons.
There might be a fanfiction where a Kitsune forms an unlikely friendship with Harry Potter. The Kitsune, with its magical and cunning nature, could help Harry in his battles against Voldemort. It could use its illusions to deceive Death Eaters and give Harry an edge in combat. Also, the Kitsune's connection to nature could introduce a new aspect of magic in the Harry Potter universe.
Maybe the female kitsune is an ancient magical being who has been asleep for centuries. Harry stumbles upon her while exploring an old, forbidden part of the Hogwarts grounds. She wakes up and initially doesn't understand the modern wizarding world. Harry helps her adapt and in the process, they develop a deep friendship that could potentially turn into a romantic relationship as they face various challenges together, like dealing with the Ministry of Magic's suspicions about the kitsune.
Perhaps the conflict between the wizarding laws and djinn lore. In the Harry Potter universe, there are strict rules about magic use. But djinn have their own set of rules and powers. Harry, as a half - djinn or something similar, would have to navigate between these two different systems. He might face challenges from both the wizarding community who don't understand djinn and the djinn who might see him as an outsider.
There could be a really interesting plot where the werebear nature of Harry Potter in the fanfiction is a closely guarded secret. He has to struggle with hiding this new aspect of himself while also dealing with his regular Hogwarts life. He might face challenges like accidental transformations during full moons and having to cover it up from his friends. And maybe the werebear side of him has a connection to an ancient prophecy in the wizarding world that only he can fulfill.
In a 'Harry Potter summons female demons' fanfiction, an interesting plot point could be that the female demons are actually the spirits of wronged witches from the past. They were cursed and turned into demons, and Harry's summoning is seen as a sign for them to seek redemption. Harry has to help them break the curse by finding a long - lost magical artifact. Along the way, they face opposition from some of the more traditional - minded wizards who believe that demons should never be allowed in the wizarding world, creating a conflict between the old ways and the new understanding that Harry is trying to bring about.
One interesting concept could be the combination of the magical world of Harry Potter with the Kitsune, which are often associated with Japanese folklore. Maybe there are Kitsune characters attending Hogwarts and bringing in their unique abilities and cultural elements. For example, their shape - shifting abilities might add a new twist to the usual magic at the school.
One interesting plotline could be the main character inheriting kitsune powers and how it affects their relationships at Hogwarts. Maybe they have to hide their new abilities from their friends at first.
