His friends' reactions would be mixed. Neville would look up to Harry even more. He might see it as a sign that even someone as young as Harry can take on great responsibility. Ginny would be excited and would likely be one of the first to volunteer to help Harry in any way she could, whether it's helping with Quidditch teams or just being a friendly face around the school. Luna would probably have some very unique and wise words for Harry, like how this new role is part of his 'destiny - path' in the magical world.
Ron would probably be both shocked and proud. He might be a bit in awe at first, but then would be Harry's biggest supporter, helping him out with any pranks or light - hearted stuff to relieve the stress. Hermione, on the other hand, would be very concerned about the workload on Harry. She would offer to help him with administrative tasks, like organizing the library or creating study schedules for the students.
His friends would be very surprised. Hermione would probably be a bit skeptical at first. She'd want to research all about Witchers before she fully supported Harry's new interest. Ron, on the other hand, might be more excited. He'd see it as another adventure and would be eager to hear all about the Witcher world from Harry.
Hermione would immediately start researching. She'd be scouring the library for any books on magical illnesses and cures. Ron would be more of the practical one, getting Harry extra blankets and trying to make him laugh to keep his spirits up. Ginny would be constantly by Harry's side, holding his hand and giving him the emotional support he needs. Neville might bring some plants from the greenhouse that he thinks could have some healing properties.
In such a fanfic, Harry might bring a lot of changes to Hogwarts. He could introduce new courses that focus on real - world magic applications, like how to use magic for environmental protection. Also, he would probably be very strict about the safety of students, especially after all his own dangerous experiences at school.
Shikamaru, being the intelligent one, would try to analyze the situation first. He would understand that Naruto isn't himself and would start to plan a way to reverse whatever happened. He might try to gather the other ninja to form a strategy. Kakashi would be deeply disappointed. He has trained Naruto and seen his growth, and this change would be like all his efforts going to waste. He would try to talk to Naruto, using their past experiences to try and break through to the real Naruto inside.
Hermione would probably be a bit worried at first. She'd be concerned about him missing out on important magical studies during the summer. But she'd also encourage him to have some normal, non - magical experiences. Ron, on the other hand, would be jealous. He'd wish he could go to a muggle summer camp too and experience something different. He might even ask Harry to bring him back some muggle treats.
The headmaster might be a bit surprised at first. He would likely respect Harry's opinion, though. He has always valued Harry's thoughts and feelings. He may start to think about the implications of fanfiction on the wizarding community and how it might affect the students and the overall perception of Hogwarts.
Hermione would probably be very curious at first. She'd want to research all about the Peverell family to understand the significance of Harry's decision. Ron, on the other hand, might be a bit more confused and a little worried that Harry is trying to distance himself too much from their group. But overall, they would support him because they are his true friends.
Hermione would probably be quite understanding. She might see it as an opportunity to promote equality and acceptance in the wizarding world. Ron, on the other hand, would likely be a bit more awkward at first, but would soon come around to support Harry once he realizes it's not a big deal.
The Weasley twins would absolutely love it. They'd see it as a great opportunity for more pranks. They might magically enhance the dress to do all sorts of crazy things, like change colors or play music, all while Harry is trying to go about his normal day at Hogwarts. And they'd be very protective of Harry if anyone made mean comments about his dress - wearing.
Well, one possibility is that there could be some sort of magical emergency that forces the school to appoint Harry as headmaster prematurely. Maybe all the other eligible candidates are incapacitated in some way. And Harry, with his experience in facing dark magic, is seen as the best option to lead the school through this tough time.
