There might be a fanfiction where Azuma forms an unexpected alliance with a Fairy Tail member. They could be forced to work together to overcome a common enemy. This would involve a lot of character development as they learn to trust each other despite their initial differences. Azuma's unique magic style would add an interesting dynamic to their partnership.
Power play can also be a theme. Given the magical and often hierarchical world of Fairy Tail, seeing how power differences play out in a yaoi relationship involving Azuma can be interesting. For example, one character might be more powerful magically, but the other has more emotional strength, and how they balance that in their relationship is explored.
Create an engaging plot. It could be a new adventure that Azuma embarks on, or a situation that challenges his beliefs. For example, you could put him in a situation where he has to choose between his loyalty to his own group and doing what is right. Also, introduce new characters or bring back old ones from the Fairy Tail series to interact with Azuma in interesting ways.
You can try fanfiction websites like Archive of Our Own (AO3). There are often many different works related to Fairy Tail, including those involving Azuma in the yaoi genre. Just search for 'Fairy Tail Azuma Yaoi' on the site, and you'll likely find a variety of stories.
It adds more content. The official Fairy Tail series has a limited number of episodes and chapters. Fanfiction fills in the gaps. For example, it can create stories about what the characters were doing during the time - jumps in the original story.
If Lucy never joined Fairy Tail, the friendships and relationships among the characters would form in a very different way. Also, many of the story arcs might not unfold as they do in the original plot.
One popular theme is alternate universes (AUs). Writers like to explore what would happen if the Fairy Tail characters were in different settings, like a modern - day high school or a steampunk world. Another common theme is romance. Fans often pair up their favorite characters in different relationships, such as Natsu and Lucy or Gray and Juvia.
Erza and Jellal are also a favored couple in Fairy Tail fanfiction. Their complex past, with Jellal's redemption arc, adds a layer of depth to their potential relationship. It allows for stories that deal with forgiveness, love that overcomes past wrongs, and the growth of their connection over time. There's also Gajeel and Levy, as their interactions in the series suggest a budding relationship that can be elaborated on in fanfics.
You can try websites like FanFiction.net or Archive of Our Own (AO3). FanFiction.net has a large collection of Fairy Tail fanfics. Just search for 'Fairy Tail' in the search bar, and you'll get a bunch of results. AO3 also has high - quality fan works, and it often has more in - depth and unique takes on the Fairy Tail universe.
The condition could be that the main character has to give up their magic for a period of time. This would create a lot of interesting plot twists as they'd have to rely on their wits and the help of their friends in the Fairy Tail guild instead of their magical abilities.
