One popular 'bts goes to hogwarts fanfic' is 'The Magic of BTS at Hogwarts'. It's really interesting as it combines the unique personalities of BTS members with the magical world of Hogwarts. For example, Jin might be in the Gryffindor house, showing his brave side while also being the 'worldwide handsome' in the wizarding world.
The sorting ceremony is often exciting. Imagining which Hogwarts house each BTS member will be sorted into is really cool. Like, will RM be in Ravenclaw for his intelligence? Another exciting part is when they face magical challenges together, just like how they face difficulties as a group in real life.
Well, it could be that Percy has a hard time adjusting to the wizarding world at first. But then he meets a mentor figure who helps him understand his place in Hogwarts and he starts to thrive. He might even join the Quidditch team and become a star player.
In this fanfic, Ciel could potentially be sorted into a Hogwarts house, say Slytherin because of his cunning nature. Then he would have to navigate the politics within the house while also exploring the secrets of the castle. He could also get involved in some kind of mystery that threatens Hogwarts and use his unique skills to help solve it.
Well, it could be about Naruto arriving at Hogwarts and being confused by all the magic there. Maybe he tries to use his ninja skills in a world full of wizards and witches.
One possibility could be that Harry discovers he has some other magical destiny outside of Hogwarts. Maybe he is taken in by a different group of wizards who teach him their own brand of magic in a hidden location. They might believe Hogwarts is too mainstream or that Harry has a special power that needs to be nurtured away from the school.
It could be Voldemort if the story takes place during the time he was a threat. Naruto's arrival might disrupt his plans in some way, so he would see Naruto as an obstacle.
Well, he'd probably shock everyone. His ninja skills like super speed and shadow clones would be a wild contrast to the magic at Hogwarts. He might make friends easily as he's used to being part of a team in his own world. And he could teach the Hogwarts students some of his combat skills in return for learning magic.
He might use his spider - powers to outperform in Quidditch. His agility could make him an excellent seeker, zipping through the air to catch the golden snitch much faster than others.
