Well, if RWBY were transported to Earth in a fanfiction, they'd probably be really confused at first. Ruby might be fascinated by all the new technology and different kinds of weapons. Weiss would likely be shocked by the lack of Huntsmen and Huntresses in the traditional sense. Blake could find it interesting how different the Faunus situation is on Earth compared to Remnant. Yang, on the other hand, would be eager to explore and test her strength against Earth's fighters, if there are any comparable ones.
The OC might interact with them in various ways. They could start by being in awe of their combat skills, like Ruby's speed. And in the harem aspect, they could show affection differently to each character. For Weiss, it could be through respecting her family name and helping her with her studies. With Blake, they might bond over books and their love for knowledge.
Well, it could be really exciting. The OC might find themselves in the middle of all the action and drama in the RWBY world. They could form unique relationships with the different characters. Maybe they'd team up with Ruby and her friends against the Grimm. And in the harem aspect, they could have some interesting romantic or friendly interactions with multiple characters, like Weiss, Blake, and Yang.
In 'rwby watches earth fanfiction', Ruby would be wide - eyed and eager to explore every new thing. She'd be constantly asking questions about how things work. Weiss would be shocked by the lack of a Dust - based power system but would soon start to admire Earth's ingenuity. Blake would be drawn to the underground subcultures on Earth, like punk or goth cultures. Yang would be amazed by the variety of fighting styles on Earth, from martial arts to boxing. They all would have to come to terms with the fact that Earth is a very different place from Remnant.
Well, Ruby would likely be the first to show enthusiasm. She loves new things and the military tech would be like a shiny new toy to her. Weiss would be more reserved, analyzing everything from a tactical and strategic perspective. She might comment on how the Earth military could improve in certain areas. Blake would be quiet at first, observing and thinking about how the military's actions could be seen as a form of power and control, much like some of the power struggles in Remnant. Yang would jump right into imagining battles between RWBY and the Earth military just for the fun of it.
RWBY characters might initially be confused by Earthlings' lack of knowledge about Dust and Semblances. They could start by trying to educate some curious Earthlings about their world. For example, Ruby might show off her Crescent Rose to a group of engineering students, who are fascinated by its design.
Well, they might be really confused at first. The cultures and settings in Earth fanfictions are so different from their own world in RWBY.

They could also be shocked by different social norms or historical events that are unique to Earth.

She might start a blog or a YouTube channel about her experiences. Weiss would struggle at first with the lack of the familiar caste system from Remnant. But she'd eventually find her place, perhaps in the art or fashion world on Earth. Blake would be on the lookout for any signs of discrimination similar to what the Faunus face on Remnant. She might get involved in activism if she found such issues. Yang would be all about experiencing new thrills. She could become a popular figure in extreme sports or in local bars where she'd show off her strength in friendly competitions. Their Semblances would also play a role. Ruby's speed could make her a star athlete, Weiss' glyphs could be used in magic shows (if Earth has something like that), Blake's shadow - like abilities could be used for cool stunts, and Yang's strength would always be an attention - getter.
Ruby's adventurous spirit would lead her to explore every aspect of the Earth military in the fanfiction. She would be like a kid in a candy store, especially when it comes to high - tech weapons. Weiss's personality of being a bit haughty initially would make her a bit of a snob towards the Earth military, but her intelligence would make her soon understand their importance. Blake's withdrawn nature would mean she would be in the background, but her thoughts would be deep as she compares the military to the power dynamics in Remnant. Yang's exuberance and love for a good fight would have her eager to see how strong the Earth military really is.
