One idea could be a crossover with 'Alice in Wonderland'. Chihiro could find herself in Wonderland and have to navigate through the strange rules and characters there, while also using her experiences from the Spirit World. Maybe she'd meet the Cheshire Cat who could be as mischievous as some of the spirits she met in Spirited Away.
A crossover with 'My Neighbor Totoro' could be really heartwarming. Chihiro might visit the forest where Totoro lives. The small spirits from Spirited Away could interact with Totoro and his friends. Chihiro could learn new things about nature and friendship from Totoro and his world.
A Spirited Away and 'Howl's Moving Castle' crossover would be cool. Chihiro could end up in Howl's world and help Sophie in some way. The soot sprites could get into Howl's castle and cause some chaos with Calcifer. Chihiro's determination and kindness could also have an impact on Howl and his journey to break his curse.
One idea could be a fanfiction that focuses on what happened to Haku after Chihiro left the spirit world. Maybe he had to face new challenges or make difficult choices. Another could be a story about Chihiro returning to the spirit world as an adult, but finding it completely changed. And a third idea could be a fanfiction that delves into the backstories of the minor spirits we saw in the movie, like the soot sprites and how they came to be in the bathhouse.
One idea could be a story about Haku and Chihiro reuniting in the spirit world years later. Chihiro has grown up but still remembers Haku vividly. Another could be a fanfiction where they go on an adventure together outside of the bathhouse to explore other parts of the spirit realm that were previously unknown to them.
One plot idea could be that the OC is a spirit from a different part of the spirit world who comes to Yubaba's bathhouse. Haku is immediately intrigued by this new spirit and they start to form a bond as they both deal with the chaos in the bathhouse. Another idea is that the OC has a special power that can help Haku break free from Yubaba's control, leading to a journey of self - discovery for both of them.
One thing that makes it interesting is the novelty. Spirited Away is a well - known and beloved story, and adding a pregnancy element shakes things up. It forces us to reimagine the characters in new situations. For instance, if No - Face were to be involved in a story with a pregnant character, his actions and reactions would be very different from what we saw in the original movie.
One idea is that Chihiro gets trapped in a different part of the spirit world and Haku has to use all his powers to find her. Along the way, he realizes just how much she means to him.
One great Spirited Away fanfiction is 'The Continued Adventure of Chihiro'. It takes place a few years after the events in the movie and has Chihiro return to the spirit world on a new quest. It's really well - written and manages to capture the same sense of wonder as the original movie.
One idea could be the exploration of how Naruto's sealing affects the crossovers. For example, if it's a crossover with the Bleach universe, the seal might disrupt the spiritual balance there. Another could be Naruto being sealed in a different dimension where the crossover characters reside, and he has to find a way to break the seal while interacting with these new characters.
First, decide which other world or story you want to cross it with. For example, if it's with 'The Little Mermaid', think about how the underwater world and the Spirit World could connect. Then, consider the characters. Maybe Ariel would be curious about the Spirit World and accidentally end up there, and Chihiro would have to help her get back. Start with a simple scene like that to set the story in motion.
Well, in a crossover with the Percy Jackson universe for 'Harry Potter runs away' fanfiction, Harry could end up at Camp Half - Blood. He'd be a bit of an oddity with his wand and different magic system. The demigods would be both intrigued and cautious. He might have to prove himself in a quest alongside them. It could be a story about different forms of magic colliding and him finding a new family among the demigods.
In this fanfiction, Haku might be searching for a way to bring some of the beauty of the human world back to the spirit world. He travels across different cities, seeing various forms of art, architecture, and nature. Along the way, he meets a botanist who teaches him about plants. Haku then decides to try and create a garden in the spirit world inspired by what he has seen in the human world. He faces many challenges in transporting the plants and knowledge, but with his determination, he tries his best to make it happen.
