One interesting Juvia Leaves Fairy Tail fanfiction could be one where she goes on a solo adventure to discover her true powers outside of the guild. In this type of fanfic, she might encounter new magical creatures and have to rely solely on her own skills.
A possible fanfiction could be that Juvia leaves to protect the guild. She discovers a dangerous plot against Fairy Tail and decides that her absence would be the best way to keep everyone safe.

One fanfiction I remember has Juvia leaving after a big fight in the guild. She feels she doesn't belong anymore.

It's a really engaging story that shows Juvia's journey in a unique way.
One interesting storyline could be Juvia's journey of self - discovery within the Fairy Tail world while facing unique challenges. For example, she might discover a new magic ability that is tied to her emotions. Another could be a romantic sub - plot where she has to overcome misunderstandings with a male character. And there could also be a story where she teams up with unlikely allies to save the Fairy Tail guild from a great threat.
One possible plot could be that Lucy and Juvia leave Fairy Tail to go on a self - discovery journey. They might want to explore their individual magic powers more deeply without the constraints of the guild. Maybe they travel to different magical realms, meet new characters, and learn unique magic techniques that they can bring back to Fairy Tail later.
She might leave due to heartbreak. For example, if she felt that Gray didn't return her feelings in the way she hoped, she could decide to leave to get over him and start anew.
One good fanfiction could be 'The Missed Chances' where it delves deep into Juvia's unrequited feelings and how Gray's realization comes a bit too late. It shows their complex relationship through different scenarios and dialogues.
One interesting Juvia Gray Fairy Tail fanfiction could be about their adventures in a parallel universe. In this story, they might have different powers or face different challenges compared to the original Fairy Tail story. For example, Juvia could have the power to control not just water, but also ice, and Gray might have some fire - related abilities in addition to his ice - make magic. This would lead to a whole new set of adventures and character developments.
One interesting plotline could be Natsu and Juvia teaming up for a difficult mission. They have different magic styles, Natsu with his fire magic and Juvia with her water magic. Their interaction during the mission, like Juvia being a bit shy around Natsu at first but then growing more confident as they face challenges together, can make for a great story.
One interesting story could be about Juvia and Gray going on a secret mission together. They face many challenges that test their relationship and their individual powers. Along the way, Juvia's love for Gray becomes even more apparent, and Gray starts to see Juvia in a new light.
A powerful magical being from another dimension could be the main antagonist. This being senses the departure of Lucy and Juvia from Fairy Tail and sees it as an opportunity to invade their world. It tries to stop the two girls from getting help or finding a way to stop it, as they are two of the most powerful mages outside of the guild protection now.
