One common theme is the struggle between good and evil. Since a fairy represents good and a devil represents evil, their relationship often involves the battle between these two forces within themselves and in their relationship. For example, the fairy may have to question her own values when she falls in love with the devil.
Well, 'Eternal Love of Fairy and Devil' is quite a good one too. It not only focuses on their love but also on the power struggles in their worlds. The author creates a vivid setting where the fairy's purity and the devil's darkness are in contrast yet also attract each other. Their love is like a bright light in the midst of the chaos of their two worlds.
One of the main themes is love that transcends boundaries. In the 'Love Between Fairy and Devil Novel', the love between the fairy and the devil breaks the traditional enmity and differences between their two kinds. Another theme could be self - discovery. As the story progresses, both the fairy and the devil characters may learn more about themselves through their relationship. Also, it might explore the theme of sacrifice, as they may have to give up certain things for their love.
I think the side characters can also be quite memorable. For example, the fairy's best friend who might initially oppose her relationship with the devil but later comes to understand. This character shows loyalty and growth. And also, the devil's minions who have their own little quirks and add some humor to the story while also highlighting the devil's character.
In fanfiction, the love between Lucy and Natsu is often depicted in very sweet ways. Writers may focus on their adventures together which gradually build a deeper bond. For example, during battles, Natsu's protectiveness over Lucy shows his special feelings. Their constant bickering also has an undertone of affection, like how typical couples in real life might tease each other.
In fanfiction, Gajeel and Levy's love is often depicted as a slow - burn relationship. Gajeel's rough exterior gradually softens as he gets closer to Levy. Their shared experiences in Fairy Tail, like going on missions together, create a bond. Levy, with her intelligence and kind heart, sees past Gajeel's tough facade. In many fanfictions, their love story is filled with moments of mutual understanding and support.
Well, without reading the actual fanfiction, it's hard to say exactly. But generally, it could be that the author wanted to combine the popular Naruto character with the magical and often wild world of Fairy Tail and added a devilish twist to it. Maybe Naruto is a devil in this fanfic, which would change his personality and abilities completely, and the story could be about how he navigates the Fairy Tail world with his new identity.
One interesting character could be a Devil Slayer who has the power to manipulate shadows. He can use the darkness not only to attack demons but also to move stealthily. His backstory of how he got his powers, perhaps from a fateful encounter with a shadow - based demon, makes him really engaging.
I recommend you to read "The Silly Girl Chances to Meet the School's Most Handsome Man", a romantic youth-love novel. It tells the story of a long-lost couple who didn't know each other when they reunited. They were forced to become enemies, but they eventually got together. I hope you like this fairy's recommendation. Muah ~😗
Maybe Naruto, as a devil, comes to the Fairy Tail world to cause chaos. He could be seeking power or revenge against something in that world. He might use his ninja skills in a twisted way, against the mages of Fairy Tail.
