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 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.
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.
In some fanfictions, Lyon and Sherry might have a story where they are training together to improve their magical abilities. Sherry could be having trouble with a particular spell, and Lyon helps her master it, leading to a stronger bond between them. They then use their combined skills to defend the guild from an outside threat.
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.
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.
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 popular theme is Lyon's relationships, like his friendship with other Fairy Tail members or his potential romantic relationships. Another theme could be his growth as a wizard, showing how he overcomes challenges and becomes stronger.
Their relationship could develop through shared experiences. For example, if they go on adventures together and rely on each other's magic abilities. They might start off as friends or comrades, and then slowly realize they have deeper feelings as they see the best and worst in each other during tough situations.
In many fanfictions, Juvia's water magic and Lyon's ice magic can combine in interesting ways. For example, Juvia can create water which Lyon can then freeze into useful shapes like shields or platforms. Their combined magic could be a powerful defense against fire - based attacks.
