Harry would be the central character, but there could also be an older Japanese wizard who serves as his mentor in the ways of Japanese magic. This wizard could have a lot of knowledge about the ancient magic of Japan. And then there could be a rival from another Japanese school who challenges Harry in magical duels and in academics. And of course, Harry's owl Hedwig could still be around, causing some amusement among the Japanese students who are not used to seeing a Western owl.
There could be a group of Japanese students who are initially skeptical of Harry but later become his allies. For example, a shy girl who is really good at Japanese magic but lacks confidence. And a tough - looking boy who is actually very kind-hearted and they all form a sort of magical study group together with Harry. There might also be a mischievous Japanese magical creature that befriends Harry and causes some chaos in the school.
Well, it could be about Harry attending a Japanese school of magic. Maybe he has to learn Japanese spells and deal with Japanese magical creatures. He might also face cultural differences in the way magic is taught and practiced in Japan compared to Hogwarts.
Perhaps some students who are jealous of Harry's fame could be antagonists. They might try to undermine him during training exercises.
Besides Harry, Ginny could be a main character. She might be interested in the sports aspect of the Egyptian school, like their version of Quidditch. And there could be a local Egyptian student who becomes friends with Harry. This student could have a deep connection to the history of Egypt and help Harry understand the significance of certain magical sites in the country. They could explore ancient temples together and face various challenges along the way.
Obviously, Harry Potter himself is the central character. Hermione and Ron would most likely be involved too. They would probably try to find a way to get Harry out of Azkaban. Dumbledore might also play a role, perhaps guiding Hermione and Ron from behind the scenes or even trying to influence the wizarding court to re - evaluate Harry's case.
Well, he might face a whole new set of magical rules. In Japanese schools in fanfiction, there could be different types of magic related to Japanese folklore. Harry would probably be very confused at first. For example, he's used to the European style of magic with wands and spells like 'Expelliarmus'. But in a Japanese school, there might be magic based on things like Shinto shrines or oni (demons). He'd have to learn new incantations and ways to use magic. Also, the social structure in a Japanese school could be different. There might be more respect for hierarchy, which is different from Hogwarts where students are a bit more equal in a way.
There could be a French wizard named Pierre who becomes Harry's friend and helps him adjust to the new school.
Obviously, Harry Potter himself would be the main character. Hagrid could also be there as he has a great love for magical creatures. There might be new students who are introduced, like a young witch or wizard from a far - off land who has different ideas about magical creatures. And of course, there could be some professors at the creature school who are experts in different types of creatures.
Obviously, Hadrian is one of the main characters. He is the version of Harry Potter with a different name. Then, we might still see characters like Hermione and Ron. They would interact with Hadrian in different ways compared to how they interacted with Harry. Their relationships could be more complex or different in nature.
There could be an older, wise ghoul teacher who serves as a mentor to the students. This character could have a lot of knowledge about the school's history and the ways of the magical world of ghouls.
A young witch named Lily who is new to Salem School and is trying to find her place among the different cliques. She has a natural talent for potion - making but struggles with charms.
