There could be a lot of interactions based on their different strengths. Haruhi is very good at handling people and coming up with creative solutions in her own world. Harry is strong in magic and has faced great evils. So when they face a problem together, like an enemy that is using both normal and magical means to cause trouble, Haruhi could use her people skills to gather information and Harry would use his magic to fight. And during their down time, they could just sit and talk about their dreams. Harry might talk about his desire to have a normal life sometimes, and Haruhi might mention her dreams of traveling the world.
Harry and Haruhi would probably start off being a bit cautious around each other. Harry might be confused by Haruhi's non - magical world ways, and Haruhi would be shocked by Harry's magic. But as they get to know each other, they could start sharing their stories. Haruhi would tell Harry about her club and her friends, and Harry would talk about Hogwarts. They might also have some comical moments when Harry tries to use magic in a normal situation and causes chaos.
One possible plot could be that Harry Potter, with his magic skills, accidentally stumbles into the world of Haruhi Fujioka. He notices that Haruhi is in some sort of trouble at school, perhaps with some mean students. Harry uses his magic to play some harmless pranks on those students to teach them a lesson. Then he starts to help Haruhi with her various club activities in a magical way. For example, he could use magic to make the common room of the host club look even more amazing for an event.
They could also start sharing secrets under the table. Snape might reveal some of his past experiences with Harry's mother that Harry never knew. In return, Harry could open up about his own fears and insecurities at Hogwarts. This sharing of personal information could lead to a newfound connection between them, changing their relationship dynamic for the rest of the fanfiction.
There's a Haruhi Fujioka crossover with a magical world. In this fanfiction, Haruhi accidentally stumbles into a magical realm. Her practical nature makes her deal with the magical situations in a unique way. For example, she uses her common sense to solve problems that the magic - users there are baffled by. It's a fresh take on her character.
Her character would likely become more responsible. Haruhi is usually carefree in the original story, but pregnancy would force her to think about the future more seriously. She'd have to start making plans for the baby, which might be a big change from her spontaneous nature.
Crossovers in general are popular because they offer a new perspective. With Haruhi Fujioka crossovers, it's not just about seeing her in a new world, but also about how the themes of the original 'Ouran High School Host Club' can be blended or contrasted with the themes of the other universe. For example, if it's a crossover with a historical setting, the modern - day ideas that Haruhi represents can create a really engaging story dynamic.
