What are the possible plot developments in the 'Harry Potter is Sesshomaru's Big Sister' fanfiction?

Well, one way it could work is if there's some sort of magical cross - over event. Maybe a powerful spell gone wrong or a mysterious portal that connects the wizarding world of Harry Potter to the feudal era where Sesshomaru is from. Harry Potter, with her magical abilities, could bring new elements to Sesshomaru's world, like using spells to combat demons in a different way. And as his big sister, she could be protective and teach him about the magic she knows.

Perhaps during the rebuilding, Harry has to deal with various magical creatures that have made the ruins of Potter Manor their home. He might have to find a way to relocate them without harming them. Also, he could be visited by friends from Hogwarts who offer their help and in the process, there are some interesting interactions and exchanges of magic knowledge.

In this fanfiction, it's likely that Harry's newfound lordship at age 7 will have a significant impact on his relationship with the Dursleys. They might be even more intimidated by him, or perhaps they try to take advantage of his new status in some way. Harry, on the other hand, could use his new power to free himself from their abuse and start living a more independent life within the wizarding world. He may also discover new magical abilities or artifacts associated with his Potter heritage that help him in his journey.

One possible plot development could be that Harry has to face a lot more internal conflict. He would be associated with a house that his friends might view with suspicion. Also, he might discover new magical abilities or powers that are related to the Slytherin heritage.

Well, one possible plot development could be that Harry has to hide his new status as an Obscurial from his friends at Hogwarts for fear of being ostracized or worse. Another could be that Voldemort somehow discovers Harry's new condition and tries to use it to his advantage, perhaps by trying to manipulate the Obscurial power within Harry. Maybe Harry has to learn to control this new, dangerous power on his own as he can't trust Dumbledore or the other teachers with this secret at first.

One possible plot development could be that Hermione is left with a deep sense of guilt and responsibility. She might then take on Harry's mission or cause in his memory. For example, if they were fighting against a new dark wizard, Hermione could become even more determined to defeat the enemy.

One possible plot development could be that Harry has to face the challenges of being a young father while still dealing with his wizarding duties. He might struggle to keep his family safe from the dark forces that are always lurking in the wizarding world.

One possible plot development could be that Harry begins to undermine the existing power structures at Hogwarts. He might start by sowing seeds of doubt among the students and teachers, just like Aizen did in his own world. Another could be that he forms a secret group of followers who are loyal to him and his new ideals.

Well, he might use soul magic to communicate with the spirits of the dead wizards. It could give him an edge in battles as he might understand the essence of his opponents' souls.

In the fanfiction, it could be that Harry faces opposition from some powerful wizarding families who don't want him as high king. They might try to undermine his rule through various means such as spreading false rumors or plotting against him. Harry would then have to prove himself worthy and strong enough to maintain his position.
