Hermione would probably be a bit critical. She is all about the original books and facts. So she might nitpick at inaccuracies in the fanfic, like wrong spells or misinterpretations of Hogwarts' history. However, she could also appreciate well - written fanfics that stay true to the essence of the wizarding world.
Well, some characters could be offended. If the fanfiction goes against the established lore or misrepresents them in a way they don't like. For instance, if a fanfiction portrays Harry as a coward, his friends might not take it well. They might feel that it's disrespectful to their real - life experiences.
Hermione would probably be extremely curious about the ghouls. She'd want to study their biology, especially the kagune. She might even try to find a way to use her magic to help the half - human, half - ghoul characters like Kaneki deal with their identity crisis.
Harry Potter might be a bit surprised. He'd probably think it's strange that people are writing about his friends' and his own relationships in such a different way. Hermione would likely be very interested in the writing style and how the authors are creating these new relationships. She might even take notes to improve her own writing. Ron would just laugh it off most of the time. He'd find it a bit odd but also funny.
Some characters might be amused. They could find the creative and often unexpected twists in fanfic quite entertaining. For example, a character from a fantasy series might chuckle at how a fanfic writer has given them a new magical ability that they never had in the original story.
Some common characters in Harry Potter fanfiction are Harry Potter himself, of course. Hermione Granger is also very popular as she is highly intelligent and has a strong personality. Ron Weasley often appears too. Then there are characters like Draco Malfoy, who has a complex character that fanfiction writers like to explore further, whether it's giving him a redemption arc or delving deeper into his family's influence on him.
Hermione would be devastated. She would likely be filled with anger and a sense of vengeance. She might immediately start researching ways to bring Harry back or to punish Barty severely.
Harry Potter himself is often a common character. Since it's a reincarnation fanfic, he could be reincarnated in different forms or with different personalities. Hermione Granger is also frequently seen as she is a very important character in the original series. Her intelligence can play a big role in the new storylines that the fanfic creates.
The Weasley family, especially Molly or Arthur, can be common. They are nurturing figures and can provide a home - like environment for homeschooling. Molly might teach home - ec related magic like cooking spells, while Arthur could share his knowledge of Muggle - related wizardry.
Luna would be very open - minded. She might see the fanfiction as just another form of magical thinking. She could find the wild and imaginative ideas in the fanfictions quite endearing and might even start to incorporate some of the concepts into her own unique view of the wizarding world.
Some characters might be amused. For example, Ron would probably find the wilder and more comical fanfictions really funny. He'd be laughing out loud at the absurd scenarios where he's made into a heroic food - loving wizard who saves the day with a well - timed puking pastille.
