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.
Willard is also quite memorable. His extreme religious beliefs and the way he forces them onto his family create a lot of the early conflict in the story. His actions have long - lasting consequences for his son Arvin. And then there is Sandy, who gets caught up in a web of lies and relationships that are full of toxicity. Her character shows the vulnerability of women in the setting of the novel.
Miranda Priestly is definitely one of the most memorable. Her powerful and intimidating presence in the fashion world makes her stand out. She is the 'devil' in the title, with her high standards and unforgiving nature.
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.
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.
Frodo Baggins is very memorable. He's a small hobbit who undertakes the huge task of destroying the One Ring. His courage and vulnerability make him stand out. Then there's Gandalf, the wise wizard. He guides and protects the fellowship, using his magic and knowledge at crucial times.
The female lead is surely one of the most memorable. Her strong will and determination make her stand out. She doesn't shy away from difficult situations and fights for what she believes in.
Jellal from the dark guild is quite memorable. His complex backstory and his struggle between good and evil make him stand out. He has great power and his actions often have a big impact on the story.
Nala is a memorable character too. She is strong - willed and plays an important role in Simba's life. Rafiki, the wise mandrill, is also very memorable. He has a spiritual connection to the story and helps Simba find his way back to his true self and his responsibilities as king.
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.
Jace is definitely one of the most memorable. His cocky attitude and his amazing fighting skills make him stand out. Then there's Clary. Her discovery of her Shadowhunter heritage and her journey to understand her powers are very interesting. Also, Simon is quite memorable. He's a normal human turned into a vampire, and his struggle to adapt to this new life is engaging.
