Another idea is that Lyon and Juvia accidentally end up in a magical realm where they are the only two from Fairy Tail. They have to rely on each other to survive and get back home. During this time, they go on 'dates' of sorts, like sharing a meal by a magical stream or watching the strange celestial events in that realm. This makes them grow closer and consider a real relationship.
A great plot idea could be that Lyon and Juvia are forced to go on a pretend date as part of a mission. They start off awkwardly, but as the date progresses, they find themselves actually enjoying each other's company. For instance, they might have to infiltrate an enemy's ball and act like a couple in love to gather information.
Perhaps there's a magical spell that makes Juvia forget her feelings for Gray and instead be attracted to Lyon. Lyon is initially skeptical but decides to go along with it. They start dating, and Lyon shows Juvia all the things he loves about the world outside of Fairy Tail. As they spend more time together, Juvia begins to develop real feelings for Lyon, even when the spell starts to wear off.
One idea could be that Juvia and Lyon are on a joint mission for the guilds. They get trapped in an ancient, enchanted forest. As they try to find their way out, they start to understand each other better. Lyon realizes Juvia's loyalty and strength, and Juvia sees Lyon's determination and skill. This shared experience could lead to a deeper bond between them.
One idea could be a story where Juvia, Lyon, and Gray have to team up to face a powerful dark wizard that is threatening the Fairy Tail guild. They start off with some tension due to their past relationships, especially between Gray and Lyon who have a rivalry, but as they battle, they learn to work together better. Juvia could also be in a position where she has to choose between protecting Gray or following Lyon's more strategic plans, adding an interesting love - triangle - like dynamic to the plot.
One plot idea could be a story where Lyon and Juvia are on a joint mission for the guild. They start off bickering like they used to, but as they face various challenges together, they gradually realize their feelings for each other. Another could be a story set in an alternate universe where Lyon and Juvia are from rival guilds and they have to overcome their guild loyalties to be together. Or perhaps a plot where Juvia gets injured and Lyon has to take care of her, which makes him see her in a new light.
One possible fanfiction could involve Juvia initially being hesitant to date Lyon because of her feelings for Gray. But as she spends more time with Lyon, she discovers his own unique charm. For example, Lyon might take Juvia on a magical adventure through the Fairy Tail world, showing her places she's never seen before, which gradually makes her heart open up to him.
One plot idea could be Lyon and Meredy going on a mission together to a mysterious, ice - covered land. There, they discover an ancient magic that is linked to both their pasts. Another could be a story where they get accidentally transported to a parallel world where they have to rely on each other to find their way back home. And a third idea is that they start training together and during the training, they realize they have feelings for each other that they didn't expect.
There could be a storyline where Juvia and Lyon are on a quest to find a rare magical item. Along the way, they encounter various obstacles like dangerous magical beasts and tricky puzzles. This adventure brings them closer as they rely on each other's strengths. Lyon might use his ice - making magic to clear paths while Juvia uses her water magic to protect them from certain attacks.
One idea could be a story where Juvia has to face her insecurities in a new and challenging situation within the Fairy Tail world. Maybe she loses her magic temporarily and has to rely on her non - magical skills and the support of her friends, which deepens her relationships. Another could be a time - travel plot where Juvia goes back in time and meets a younger version of herself, and they have to work together to change an event in Fairy Tail's history. Or perhaps a story where Juvia discovers a hidden power within her that has been dormant all this time, and it changes how she is perceived within the guild.
One idea could be a story where Juvia and Erza team up for a dangerous mission. Maybe they have to infiltrate an enemy stronghold. Juvia's water magic can be used for stealth and distraction, while Erza's versatile combat skills handle the direct fighting.
In the fanfiction, Juvia might move on with Lyon by gradually realizing his positive qualities. Maybe Lyon shows her a different kind of love and understanding compared to what she previously experienced. He could be there for her during tough times, and through shared adventures and quiet moments, Juvia starts to see a future with him.
One plot idea could be that Natsu and Juvia are on a mission together in a mysterious, ice - covered land. Juvia's water magic is affected by the extreme cold, and Natsu has to use his fire magic to keep her safe while they search for a powerful, lost artifact. Along the way, they start to understand each other better and develop a deeper bond.
