A possible plot could be centered around a new villain that is a threat to both worlds. This villain could be attracted to the unique energies of both the Inuyasha universe (like the Shikon Jewel) and the Fruits Basket world (the Sohma family curse). The characters from both series would have to gather together. Yuki could use his charm and intelligence to help Inuyasha strategize. Sango and Miroku could work with the Fruits Basket characters to protect the innocent. And all of them would be on a journey to stop this new and powerful enemy.
Well, it could be really interesting. Maybe the characters from Inuyasha end up in the world of Fruits Basket. Inuyasha might be confused by all the Sohma family secrets and the whole curse thing. And the Fruits Basket characters could be scared of Inuyasha at first with his demon side. But then they could learn from each other. For example, Tohru could teach Inuyasha about kindness and acceptance in a different way than Kagome does. And Inuyasha could show the Fruits Basket characters how to be brave in the face of danger.
Inuyasha's sword, Tessaiga, could be used in interesting ways in the Fruits Basket world. For example, if a Sohma is in trouble during their transformation, Inuyasha could use Tessaiga to protect them. On the other hand, the Sohma's zodiac animal abilities could assist Inuyasha in his battles. Like Kyo's cat - like strength and agility could help Inuyasha in a fight against a particularly fast demon.
Well, it could be really interesting. Maybe Naruto characters could end up in the world of Fruits Basket. Naruto might be confused by the Sohma family curse at first. He'd probably try to use his ninja skills to solve the problems there. For example, he could use his shadow clone jutsu to help out in various tasks around the Sohma house.
Well, it could be really interesting. Maybe the characters from Harry Potter could visit the Sohma family in the Fruits Basket world. Harry could be shocked by the curse of the Sohma family and try to find a magical solution to break it. Hermione would be busy researching about the unique situation in Fruits Basket using the library in Hogwarts. Ron might be a bit clueless at first but would gradually get involved in the strange happenings.
One interesting storyline could be Inuyasha ending up in the world of Fruits Basket. He might initially be confused by the strange curse and the family dynamics. For example, he could mistake the Sohma's transformation for some kind of demon magic he doesn't understand. His brash nature might clash with some of the more reserved Fruits Basket characters like Yuki, leading to some humorous and tense situations as they try to figure out how to send Inuyasha back to his own world.
Inuyasha and Kyo would definitely have some interesting interactions. They are both hot - tempered. Inuyasha might see Kyo as a bit of a rival at first. Kyo would probably be curious about Inuyasha's demon form. Another pair could be Kagome and Tohru. Kagome is strong - minded and Tohru is very kind - hearted. They could learn a lot from each other, like Tohru could show Kagome how to be more patient in certain situations.
A possible plot could involve the characters from both series swapping their worlds. So, the Fruits Basket characters end up in the Victorian - era setting of Black Butler. Tohru Honda might be mistaken for a servant in the Phantomhive household. Her kind nature could either be a source of confusion or a way to bring some warmth to the often - dark and brooding environment. And Sebastian might be intrigued by the Sohma curse, seeing it as an interesting oddity in his long existence.
One idea could be to have the characters from 'House' end up in the world of 'Fruits Basket'. Maybe House could try to diagnose the curse that plagues the Sohma family. His rational and often brusque approach would clash with the more emotional and superstitious aspects of the 'Fruits Basket' world.
In such a fanfiction, the relationships in 'Fruits Basket' could be mirrored in Pokemon relationships. The deep friendships and rivalries in Pokemon could be explored in a more 'Fruits Basket' - like way. For instance, the relationship between Ash and Gary could be developed to have the same kind of complex feelings as some of the characters in 'Fruits Basket', with a mix of envy, admiration, and friendship. There could also be a focus on the acceptance of different Pokemon types, similar to how the characters in 'Fruits Basket' learn to accept each other's differences.
I think Naruto himself would be really interesting. His boisterous personality and determination would be a great contrast to the more reserved characters in Fruits Basket. He would bring a lot of energy and his can - do attitude into the Fruits Basket world.
The characters would have some really interesting interactions. For example, Sebastian would likely be polite yet calculating when dealing with the Sohma family. He might see them as an interesting study, especially those with the animal curse. Tohru, being her kind self, would probably try to befriend Ciel and the others. However, Ciel might be initially suspicious of her overly - nice demeanor, as he's used to a world full of deception.
