What could be the reasons for Natsu and Mirajane to leave Fairy Tail in fanfiction?

One possible reason could be to seek new adventures. They might feel they've reached a point in Fairy Tail where they've done all they can and want to explore new magic and challenges elsewhere. For example, they could have heard of a far - off land with a different type of magic that they are eager to learn about.

The story would have to shift its focus. Instead of relying on Natsu's dragon - slayer magic and Mirajane's take - over magic, new characters or existing ones would need to shine. This could open up new plotlines such as the discovery of new magic among the remaining members or the forging of new alliances outside of the guild to compensate for the loss of Natsu and Mirajane. It would be a major turning point in the fanfiction's narrative.

One possible plot could be that Natsu and Mirajane join Fairy Tail at different times. Natsu might bring his usual enthusiasm and powerful fire - based magic. He could quickly get into all sorts of adventures, making friends and enemies alike. Mirajane, on the other hand, could use her Take - Over magic to be a great asset in battles. Their joining could lead to new team - ups within the guild, like Natsu and Mirajane going on a mission together to stop a dark wizard who is causing chaos in a nearby town. They'd face challenges, but their combined skills would help them overcome the odds.

In fanfiction, Mirajane and Natsu could have a very interesting mentor - mentee relationship. Mirajane, being more experienced, could teach Natsu some new magic techniques or how to better control his power. This would add a new dynamic to their interactions within the Fairy Tail guild.

One characteristic is the exploration of their personalities. Natsu's brash and hot - headed nature contrasts with Mirajane's more composed and sometimes mysterious side. In fanfiction, this contrast often leads to interesting interactions. For example, Natsu might be the one to break through Mirajane's reserved exterior with his straightforwardness.

One possibility is that they leave to explore a new land filled with unknown magic. They might be on a quest to find a powerful magic item that could help Fairy Tail in the future.

It could be a powerful dark wizard who has a grudge against Fairy Tail. This wizard might see Natsu and Mirajane's joining as an opportunity to strike at the guild when it's in a state of flux. He could be someone who was once defeated by Fairy Tail in the past and has spent years building up his power for revenge.

There are indeed some great ones. In some fanfictions, they might start off as friends but gradually realize their deeper feelings for each other. For example, a story could have Natsu noticing Mirajane's different sides during a difficult mission, and that newfound understanding leads to romantic feelings. Another common theme is where Mirajane has to help Natsu deal with his past traumas, and through that process, love blossoms between them.

Entropy in a Fairy Tail fanfiction related to Natsu and Mirajane could refer to the chaos or disorder within their relationship or the situations they face. It might be used to add an element of unpredictability to their interactions, like in a story where Natsu's impulsive nature and Mirajane's more complex personality create a chaotic dynamic that is full of unexpected twists and turns.

One reason could be that some writers might want to create a more complex or darker storyline. By having Natsu be hated, it adds conflict. Maybe they portray him as having made a big mistake that the other characters in the fanfic can't forgive.
