It could be inspired by her dreams. People often get creative ideas from their dreams. Lucy might have had some vivid and interesting dreams that she wants to expand on and turn into a novel. She could be exploring new worlds, characters, and storylines that came to her during sleep.
As I don't know the 'lucy star story', I can't determine who the main character is. But based on the name, it seems that Lucy might be the main character.
To develop Lucy's child character, start with their magic. If they inherit celestial spirit magic, show how they learn to summon and communicate with the spirits. Also, consider their personality. They could be brave like Natsu, or more calm and collected like Gray. Their relationships are important too. How they interact with the older Fairy Tail members can shape their character. For example, if they look up to Erza, they might learn about discipline from her.
This type of situation in fanfiction can be a turning point for Lucy's character development. Firstly, it can test her resilience. She has to deal with the immediate shock and embarrassment, and how she bounces back shows her strength. Secondly, it can change her relationships. Her friends' reactions to her situation might make her re - evaluate who she can truly trust. And finally, it can make her more assertive. She may decide that she won't let such things happen again without her consent, leading to her taking more control in various situations.
Hypnosis can have a significant impact on Lucy's character development. For example, if she's hypnotized to overcome her fears, it can make her more courageous. She might become more assertive in battles and in her relationships within the guild. If she's hypnotized against her will, it can show her vulnerability and how she copes with being out of control. This can lead to her developing new strategies to protect herself in the future.
Lucy could be developed further by exploring her family background more deeply. Maybe she discovers some long - lost relatives who are also involved in magic. This could add new layers to her character. Another way is to show her struggling with her insecurities about her magic abilities and then gradually overcoming them through various challenges.
Death the Kid would be an extremely interesting character for Lucy to interact with. His obsession with symmetry and his powerful abilities as a meister could lead to some really unique scenarios. Lucy might be both fascinated and a bit put off by his quirks at first. But as they get to know each other, they could learn a great deal from one another. For example, Death the Kid could help Lucy understand the importance of precision in combat, which could enhance her use of celestial spirit magic, while Lucy could introduce him to the concept of celestial spirits and their different powers.
For Laxus, he might become more gentle and patient. Usually seen as a tough and somewhat brash character, having a baby could soften him. He would learn to control his temper better around the baby. For Lucy, she would likely become more confident in her maternal abilities. She has always been kind - hearted, but now she has to be strong for the baby. She might also develop new magical skills or ways to protect the baby.
There's not enough information to really know who Lucy specifically is. She could be just a regular reader of fanfiction who took the time to rate this piece as M. Maybe she's part of a fanfiction community where people rate works to help others know what to expect.
