Hermione could be important. She might be the one who encourages Harry to drop his mask, or she could be the first to notice the change when he does. Another could be Ron, as Harry's best friend, his reaction to Harry dropping his mask would be significant.
His friends would be affected. For example, Sasuke might see Naruto in a new light and realize that they are more similar than he thought, both having their own inner struggles. Sakura would also be more empathetic towards Naruto and might try to be a better friend, offering more emotional support.
Ron could also play a significant role. He could be initially shocked by Harry's revelation but then stand by his side. And perhaps there could be a new character, someone who has been observing Harry all along and has a hidden agenda related to his true self that is now exposed.
Hermione would probably be involved. She could help Harry research about the island, like its history and any magical properties it might have.
There could be a local wizard who becomes Harry's mentor in a way. Since Harry is on his own, he might seek guidance from someone outside of his usual circle, like an old hermit - like wizard who has a lot of knowledge about the more hidden parts of the wizarding world.
Hermione could be important. She might help Harry in his journey as a mage, using her intelligence to research and understand new magical concepts that Harry discovers.

And then there could be a new character, a powerful mage who becomes Harry's mentor and teaches him the deeper secrets of magic.
Well, in this fanfiction, it could be that Harry drops his mask as a form of self - discovery. He has been living with a false identity or a pretense for so long that when he drops the mask, he starts to explore who he really is. He might find new powers or a new purpose in life.
Well, it could be about Harry finally revealing his true self that he has been hiding behind a mask, perhaps his true emotions or a secret identity. Maybe he drops the mask in a moment of great stress or revelation.
Well, Gandalf would probably be a main character too. He is a powerful wizard in Middle - earth and his knowledge and guidance would be crucial in a story where Harry is involved. He could be the one to help Harry understand the differences between his magic and the magic of Middle - earth. Also, Aragorn could be part of it. His leadership and warrior skills could be something that Harry looks up to or tries to learn from in this fanfic.
Hermione would probably be one of the main characters. She's smart and resourceful, so she could help Harry with the administrative side of running the orphanage, like handling finances and paperwork.
