What could be the plot of a 'Harry Potter raised by his older sister' fanfiction?

Their parents' old friends could be main characters. They might come to check on Harry and his sister, bringing gifts and stories about their parents. These friends could offer guidance and protection when needed.

The plot might revolve around the older sister being a part of a prophecy too. Just like Harry, she has a special destiny. But instead of being in the spotlight like Harry, she works behind the scenes to ensure Harry's success in the fight against Voldemort. She could be the one who finds out about Horcruxes first and guides Harry in that direction, all while dealing with her own challenges at Hogwarts, like trying to keep her identity as Harry's sister a secret from the wrong people.

In a 'Harry Potter and His Little Sister' fanfiction, the sister could be a new student at Hogwarts when Harry is in his later years. She struggles to fit in because of being Harry Potter's sister. Harry has to help her deal with the pressure, make friends, and also face the threat of a new dark wizard who has a vendetta against the Potter family.

One possible plot could be that Lemon discovers she has a special magical ability that is different from Harry's. For example, she might be able to communicate with magical creatures in a unique way. Harry then has to protect her from those who might want to use her ability for bad purposes.

Maybe an original character could be created. This sister could be a powerful and wise ninja who has been traveling the world. She comes back to the village just in time to take Naruto under her wing. She could have a special kekkei genkai that she helps Naruto understand and perhaps develop in himself.

In a 'naruto raised by older sister fanfiction', the older sister could be very nurturing. She might take Naruto away from the village for a while to train him in seclusion. This way, Naruto can grow stronger without the constant pressure and discrimination in the village. And when they return, Naruto surprises everyone with his newfound skills and confidence.

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.

The plot could be that Harry, raised by demons, has unique powers that other wizards don't. For example, he might be able to communicate with dark creatures more easily. The demons could be using Harry as a tool to infiltrate the wizarding world. When he gets to Hogwarts, he starts to question his upbringing as he sees the kindness and different ways of magic there. He has to decide whether to stay true to his demon - raised self or embrace a new way of life.

One possible plot could be that Calypso, with her magical abilities, imparts a different kind of magic knowledge to Harry. Maybe she teaches him more nature - based magic, which is different from what he would learn at Hogwarts. Harry might grow up in a more isolated and peaceful environment with Calypso, away from the prying eyes of the wizarding world in Britain. This could lead to him having a different perspective on magic and his role in the fight against Voldemort.

The fanfiction might explore how Harry's relationship with the wizarding world is different. Growing up in Potter Manor, he could be seen as a more prominent figure from a young age. The manor itself could hold hidden chambers filled with challenges and rewards. Harry could stumble upon a chamber that tests his Potter lineage, like a series of magical trials. This would not only strengthen his magical abilities but also deepen his connection to his family name and the responsibilities that come with it.
