Since I haven't read this particular fanfic, it's hard to say for sure. But it could feature Naruto himself as he often has to deal with various threats in fanfics. Or perhaps it could focus on a new character that the author has created who is the so - called'real monster'.
There are several possibilities. It might be Sasuke, as he has a complex character arc in the original series and could be portrayed as a'monster' in some new way in this fanfic. Another option could be Orochimaru. He's always been somewhat of a monstrous figure in Naruto, and this fanfic could further explore his character or create a new situation around him being the main'monster' - like entity.
In a 'the real monster naruto fanfic', the main characters could also include some of the Jinchuriki. They already have a powerful and often misunderstood force within them, which could be developed into a'monster' concept. For example, Gaara was once seen as a monster in the original series because of Shukaku. This fanfic could expand on that idea with other Jinchuriki characters.
It depends on the specific fanfic, but often it could include Naruto - like characters who have the shifter ability. Maybe Naruto himself could be a shifter in some versions, or new original characters created specifically for the fanfic.
Obviously Naruto is one of the main characters. He's likely the central figure around which the story of the ranch and the monster girls revolves. His ninja skills and personality traits would play a big role in how he manages the ranch.
I'm not sure specifically as there could be many different interpretations in a Naruto fanfic titled that. It might be about a character in the Naruto universe who is seen as a real monster, either in terms of their power, appearance or actions. For example, it could be about a villain with a terrifying and inhumane nature.
Obviously Naruto himself is a main character. He is the center of the story in this fanfic as it's about his 'real face'.
Naruto himself could be one of the main characters. He could bring his energy and ninja spirit to the ranch. And of course, some of the monster girls could be main characters too. For example, a kind - hearted monster girl who is good at taking care of the ranch animals.
Since I haven't read it, I can't say for sure. But it might include Naruto and some of his friends as they are central to the Naruto universe. And of course, the character who is proposed as the'real' fifth Hokage.
Obviously, Naruto would be one of the main characters. Since it's a Naruto - centered fanfic, he's likely to be at the core of the story. There might also be his friends like Sasuke and Sakura. They could play important roles in how they deal with Naruto's'monster' transformation or whatever the story has in store for him.
I'm not sure since I don't know the specific 'the real monster story'. It could be the people who encounter the so - called monster. Maybe it's a group of villagers who have to deal with a strange and dangerous being.
Well, one of the main themes is transformation. Naruto goes through some sort of change into a monster - like form or gains monster - related powers. This transformation affects not only his physical appearance but also his relationships. Another theme is the exploration of the unknown. The world of monsters in these fics is often mysterious, and Naruto has to explore it. And of course, there's the theme of friendship. Even though he's dealing with monsters, his friends still play an important role in his journey.
Well, obviously Harry is the main character. He is the one with the monstrous side. And often, his friends like Ron and Hermione are also important characters as they might either help him or be in the dark about his true nature.
