It changes the setting completely. Instead of Hogwarts or other known places, he's in a tree. This would mean different interactions, like with forest creatures instead of classmates.
Well, one interesting plot point could be how Harry decorates his tree - home. Maybe he uses magic to create cozy nooks and crannies, or he might have floating candles and bookshelves made of branches. Another could be his interactions with the Hogwarts staff when they find out he's living in a tree. Do they try to get him back to the castle or do they support his little adventure?
One possible 'child harry potter lives in a tree' fanfiction could be about Harry finding a secret treehouse in the Forbidden Forest where he goes to escape the chaos at Hogwarts sometimes. He might discover magical creatures that live in the tree with him and form unique bonds.
Yes, there are likely many fanfictions where Harry Potter is depicted as living in Potter Castle. Fanfiction writers often like to explore different scenarios for their favorite characters, and having Harry live in his family's castle could be an interesting concept.
One possibility is that in this fanfiction, Rumpelstiltskin's magic has influenced the Black family's ability to manipulate time or space, which could be related to their family's dark arts. Another aspect could be that Rumpelstiltskin has a role in the family's pure - blood ideology. He might have been involved in some pact to keep the bloodline pure, and his actions now are starting to surface in the modern - day Black family members like Sirius or Bellatrix. For example, he could have placed a curse on the family tree long ago that is now causing problems for the younger Blacks.
In this kind of fanfiction scenario, it would be really interesting. Harry might have to adapt to Japanese culture while still having his magical abilities. Maybe he would attend a Japanese wizarding school that has some unique features inspired by Sekirei. For example, the school could have some sort of spirit - like the Sekirei - associated with it in a magical way.
I'm not sure specifically as I haven't read that exact fanfiction. But it might be a story where Harry Potter somehow ends up on Naboo (from the Star Wars universe) and has all sorts of adventures there. Maybe he uses his magic in a world that's very different from the wizarding world he's used to.
