Adventure is also a big theme. They could embark on a journey together, like searching for a lost artifact or trying to stop a powerful villain. In these adventures, they grow both as individuals and as friends. In some fanfictions, their adventure takes them to new and unknown lands within their respective universes.
There's also 'Naruto and Seilah: A New Alliance'. In this fanfiction, their two different worlds collide when a common enemy threatens both. It's full of action scenes where they combine their skills to fight off the bad guys. It also has some really interesting character development for both of them.
Seilah is another important character. She likely has her own unique personality traits that interact with Natsu's in interesting ways. Maybe she is more reserved at first but as the story progresses, she opens up more to Natsu.
Another plot could be a story set in a different time period. They are transported to the past and have to adapt to the old ways while also trying to find a way back to their own time. In this journey, they rely on each other a great deal and their bond becomes unbreakable.
Seilah is also a main character in this context. She has her own set of powers and a rather complex personality in the Fairy Tail universe, which can be further explored in fanfiction.
I'm not sure specifically what the'seilah new story' is about as there's not enough context. It could be a new story in a book, a movie, or some other form of media.
Sure. A lot of fans prefer to write and read stories that focus on the adventure and magic aspects of 'Fairy Tail' rather than adult - themed content. Check out the general 'Fairy Tail' fanfiction sections on popular websites. Some might be centered around Seilah's backstory, her relationships with other characters in a non - romantic or non - adult sense, like her role within the guild or her magical abilities.
In some fanfictions, they might team up against a common enemy that was not in the original story. This could show a different side of their relationship, like Natsu having to rely on Seilah's more strategic thinking.
One interesting plotline could be Seilah's redemption arc. Maybe she tries to atone for her past actions and find a new place in the Fairy Tail guild. Another could be her teaming up with other characters to face a new, powerful dark magic threat that has nothing to do with any adult themes.
