I'm not entirely sure as it depends on the specific fanfic. It could be about magical adventures in a world related to 'akebi no hana', perhaps with unique characters and their own stories.
One common theme could be friendship. Oto and Maho might be portrayed as having a deep and meaningful friendship that overcomes various obstacles. Another theme could be adventure, where they go on exciting journeys together.
One possible scenario could be that the Maho Girls Precure are on a mission when they encounter a powerful magic that starts to transform them into origamis. As they transform, they gain new powers related to the properties of origami, like being able to fold and unfold themselves to dodge attacks or create origami - based weapons. They then use these new abilities to defeat the evil that threatened them.
As I don't know the exact story, I can't say for sure. But generally, key elements could include the characters Maho and Anchovy Black, their goals, and the setting where the story takes place.
There is not enough information provided to give a detailed account of the 'Maho and Anchovy Black Story'. It could be a story that has elements like mystery if it's in the genre of mystery stories. Or it could be a heartwarming tale if it focuses on relationships. However, without additional details, we can only guess about the nature of this story.
Well, 'g maho visual novel' could potentially be a niche or indie visual novel. It might have unique art styles, storylines that revolve around magic elements. Maybe it has a cast of interesting characters, like wizards, witches, or magical creatures. The 'g' in it could stand for something specific, perhaps a genre like 'girl - centered' if it's about female characters in a magical setting. But without more information, it's hard to say for sure.
Since I haven't read this light novel specifically, it's hard to say for sure. But from the title, it might have something to do with 'forbidden' or 'wrong' magic (as'machigatta' can mean wrong or incorrect). It could be about the consequences of using the wrong kind of magic in a world where magic exists.
I'm not sure of specific oto x maho fanfiction stories off the top of my head. You could try searching on fanfiction websites like Archive of Our Own. They usually have a wide range of fanfictions, and you might find some interesting oto x maho ones there.
The plot might develop as the girls realize that their transformation into origamis is part of a bigger plan by an evil force. The evil force wants to use their new forms to control the balance between the magical world and the normal world. So, the Precure girls have to fight against this while still getting used to their origami bodies. They could learn special origami - based spells that are only accessible in their transformed states, and they must master these spells to defeat the evil and break free from the unwanted transformation.
