One possible plot could be that Midnight uses his magic to trap Lucy in a dream - like world. In this world, he challenges her to various magical tasks. As they interact more, Lucy starts to understand Midnight's past and the reasons behind his actions. Eventually, she manages to break free from the dream world using her Celestial Spirit magic and in the process, Midnight has a change of heart and decides to turn away from his evil ways.
Well, it could be that Lucy and Midnight are forced to team up against a common enemy. They initially dislike each other but as they fight side by side, they begin to respect each other's powers. For example, Lucy could call upon her Celestial Spirits to help them in battle, and Midnight uses his illusion magic in creative ways. Their relationship could develop into a friendship, with Lucy seeing the good in Midnight that was hidden before.
In a fanfiction, perhaps Midnight has a secret mission that requires Lucy's help. He approaches her secretly and at first, she is hesitant. But when she realizes the importance of the mission, she agrees. Along the way, they face many obstacles. Midnight might be injured and Lucy has to use her healing skills she learned from her Celestial Spirits. This experience brings them closer together and they form an unexpected bond.
Midnight might use his illusions to make Lucy think she's lost her Celestial Keys. This would be a huge psychological blow to her. But then Lucy could remember the bond she has with her spirits and break through the illusions. It would be a battle of wills as much as magic.
One great fanfiction could be where Lucy has to outwit Midnight in a battle of magic. Maybe she uses her Celestial Spirit powers in a new and creative way to overcome Midnight's illusions. It could be an action - packed story with lots of twists and turns.
One good 'Fairy Tail Midnight x Lucy' fanfiction could be 'Midnight's Star'. In this fic, Midnight and Lucy's relationship develops in a unique way as they face a common enemy. It has a great plot that keeps you engaged.
One possibility is that it focuses on a love story between Lucy and Rufus. They start off as rivals, perhaps competing in a magic competition. But as they get to know each other better, they realize they have more in common than they thought and fall in love. This could involve them sharing their dreams and fears, and overcoming obstacles together to be with each other.
Some people like it because it offers a new and different relationship dynamic compared to the more common pairings in 'Fairy Tail'. Midnight has an interesting character with his own powers and backstory, and pairing him with Lucy creates unique story possibilities.
One idea could be that Jackal, after some soul - searching, decides to turn over a new leaf and teams up with Lucy. They could go on a mission to retrieve a powerful magical artifact that was once used by an ancient dark wizard. Along the way, Jackal's knowledge of the dark arts helps them navigate through various traps, while Lucy's celestial magic provides the offensive and defensive power they need.
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.
In this fanfiction, perhaps Lucy joins Fairy Tail right after she discovers her magic abilities. This would change a lot of the initial interactions. She could be more naive and inexperienced when joining, which would lead to different dynamics within the guild. Like, she might be more reliant on the others for guidance in using her magic, rather than having some basic skills already when she actually joins in the original story.
Well, one possibility could be that it's a really innocent situation. Maybe they got into some kind of magical mishap that made them dirty and the only available place to clean up was a shared shower area. But they're both really embarrassed and trying to be respectful of each other's space while also dealing with the comical aspect of the situation.
One possible plot twist could be that Lucy initially refuses Natsu's proposal because she fears it will change their dynamic in the guild. She might think that getting married will make them less focused on their adventures and more on domestic life.
