It depends on personal taste. Some people love Ruby Dixon's work on Fantastic Fiction because of her creative world - building. However, others might find it not their cup of tea as her writing style could be a bit different from mainstream. But overall, she has a lot of fans who enjoy her contributions to the genre.
Ruby Dixon writes various types of stories in Fantastic Fiction. She often writes about adventure - filled tales with strong female characters. These characters face different challenges in strange and exciting worlds.
Well, in 'She Belongs to the Mafia King' novel, it could be that the girl is somehow forced to be associated with the mafia king at first. As the story progresses, she might start to understand his world better and even fall in love with him despite the immoral and dangerous nature of the mafia. There could be rivalries within the mafia that she gets caught up in too, like other gangs trying to use her to get to the king.
Well, without reading it, it could be about a character in the Naruto universe who the author believes belongs to someone in particular. Maybe it's a story of possession or loyalty within the context of Naruto's world, like a ninja having a special bond with another and the story revolves around that sense of 'belonging'.
Well, it's a common trope in fanfiction. Sometimes Pyrrha's soul going into Ruby is used to drive the plot forward and explore deeper character connections.
The main characters are likely the girl who belongs to the mafia king and the mafia king himself. There may also be other important characters like his henchmen or rivals in the mafia world.
Another theme is redemption. Sometimes, the fanfiction might explore the idea of Bellatrix having a change of heart through her interactions with Hermione. It could be that Hermione's goodness starts to chip away at Bellatrix's dark nature.
Since I don't know the story, it could be about a woman who enters the world of a billionaire. Maybe she starts as an employee or something and then they fall in love.
Some Naruto - related forums might also be a good place to search. There are often sections dedicated to fanfiction sharing. Members might be able to direct you to the specific 'She Belongs to Me Naruto Fanfic' if they are familiar with it.
