Perhaps he'll meet a mysterious old wizard who lives in a secluded temple in the mountains. This wizard could be a master of ancient Japanese magic and could teach Harry about the spiritual side of magic that is deeply ingrained in Japanese culture. Harry might also meet a group of young Japanese witches who are training to become magical healers. They could share their knowledge of Japanese magical plants and how to use them for healing, which would be very different from the healing methods Harry learned at Hogwarts.
In this fanfiction, Harry could discover a whole new magical world in Japan. He might encounter Japanese magical creatures like the tanuki which has magical abilities in Japanese folklore. He could also study different forms of magic that are unique to Japan, such as some types of onmyodo magic. And perhaps he'd make new friends among Japanese wizards and witches who have a different culture and approach to magic compared to those in the UK.
There's a fanfic titled 'Escape and Rediscovery'. Female Harry Potter runs away after feeling betrayed by some of her so - called friends at Hogwarts. She travels far and wide, learning different forms of magic from various sources. It has a really unique plot and great character development.
One idea could be that Fem Harry Potter runs away because she feels suffocated by the expectations placed on her at Hogwarts. She might head to the Forbidden Forest where she discovers a hidden magical community that has been living in seclusion. This new community could teach her different forms of magic that she was never exposed to at school.
In this fanfiction, perhaps Harry Potter would find the small town of Forks very different from the wizarding world. He might be intrigued by the normal, yet somehow mysterious human life there. He could make new friends who have no idea about magic and have to keep his own identity a secret to avoid chaos.
Perhaps she would form her own group of allies. These could be other outcasts from the wizarding world. They would work together to fight against the dark forces that she was running from in the first place. It could lead to some epic battles and a lot of character growth.
One possible plot could be that Harry and Fleur run away to escape the chaos of the wizarding world. Maybe they go to a far - off land where they can live in peace and explore magic on their own terms. They might discover new spells and magical creatures together.
Well, one possibility is that Harry gets tired of all the danger and attention in the UK wizarding world. He might stow away on a ship or use magic to transport himself to America. Once there, he could discover new magical creatures and spells unique to America. Maybe he'd meet some American wizards who have a different approach to magic compared to the British.
The Weasley family could also be of great help. Molly Weasley, in particular, has a motherly instinct. She could take Harry in and help him with the pregnancy as if he were one of her own children. The Weasley twins might also be able to create some useful magical items for Harry to use during his time away, like special potions for a healthy pregnancy or charms to keep him hidden. And Ron, as Harry's best friend, would be there to support him emotionally and physically, even if he was initially shocked by the situation.
