Well, in the normal series, the relationships are mainly based on the devil trying to conquer the world in his own way while living among humans. But in a lemon fanfiction, perhaps the characters could develop closer relationships through shared experiences with lemon - related things. For instance, if there is a lemon - picking event, the characters might bond over the competition of who can pick the most lemons. This could lead to new friendships or even romantic feelings between characters who previously didn't have much interaction.
The relationships could be developed differently by introducing lemon - based magic into the mix. Let's say a character gets cursed with a lemon - magic spell that makes them act out of character. The others have to help them break the spell, and during this process, they learn more about each other's true feelings. For example, Emi could see a more vulnerable side of Maou when he is affected by this spell, and this could change the dynamic of their relationship from just being enemies to something more complex and potentially friendly or even more.
Another way is by exploring their pasts. Maybe they discover that they have more in common than they thought in terms of their upbringing in their respective worlds. This newfound knowledge can make them more empathetic towards each other. For instance, if they find out that they both had a mentor figure who had a big impact on their lives, it could create a bond.
To develop Katniss differently, she could be given a more curious side when it comes to Clove. She could actively seek to understand Clove's culture and traditions from their district. This would make her more accepting of Clove. For Clove, she could be developed to be more forgiving. In the original, she's very vengeful towards Katniss. But in the fanfiction, she could learn to let go of past grudges and see Katniss in a new light. This could lead to a more harmonious relationship between them as they navigate the challenges in the story.
In this fanfiction, Katniss could develop a sense of humor around Glimmer. She could crack jokes and be more relaxed in her presence, which is a big change from her usual serious self. Glimmer could be developed to be more of a strategist. She could come up with plans that Katniss hadn't thought of, and this new role for her would change the dynamic between them. They would start to see each other as equals in terms of their contributions to their survival or whatever goals they have in the story.
One way to develop them differently is to give Tamako more assertiveness. Instead of being the somewhat shy girl, she could be more forward in expressing her feelings to Mochizou. For Mochizou, he could be made more conflicted. Maybe he has dreams outside of the town that conflict with his feelings for Tamako. This would add depth to his character.
The Devil himself is surely a main character. He brings his own unique personality and powers into the harem scenario.
In some fanfictions, the main characters could also include side characters from the original work that are given more prominence. For instance, a character like Chiho Sasaki might be developed further and become a central figure in the fanfiction's plot, especially if the story focuses on the relationships between the devils and the humans around them.
The main character is likely the devil himself. Since it's related to Lucifer, he would be a central figure. There may also be other characters who interact with him, perhaps humans in the part - time job setting or other supernatural beings that are part of the fanfiction's universe.
Sadao Maou's ability to manipulate magic could potentially be used to enhance Naruto's ninjutsu. Maou might be able to add an extra layer of power or a different effect to Naruto's jutsus. On the other hand, Naruto's shadow clone jutsu could be a very useful tactic in the battles in The Devil is a Part - Timer world, where numbers and strategic use of clones could give an edge.
Their relationship can be developed through shared experiences. For example, if they go on a mission together to save a human from a demon's curse. During this mission, they would have to rely on each other, communicate more, and understand each other's strengths and weaknesses better. This would bring them closer and deepen their relationship.
Lucifer himself is often very popular. Fans like to explore his complex personality, his struggle between his devilish nature and his new life in the human world.
