A unique take could be to make it a time - travel story. Juvia somehow travels back in time or forward to a different era in the Fairy Tail universe while being naked. This could lead to all sorts of interesting situations. She might have to adapt to the different ways of that time, while also dealing with her embarrassment. And her actions in this new time period could have unforeseen consequences for the future of Fairy Tail.
Another plot could revolve around Juvia's feelings of embarrassment being tied to her love for a certain character, let's say Gray. She might end up in a naked and embarrassing state in front of him, which could lead to some comical yet heart - warming moments as she tries to maintain her dignity while expressing her love.
Use humor. You can make the situation funny. Like the other Fairy Tail members' reactions can be comical. Gray might be blushing and trying to look away while Natsu is just being clueless and asking dumb questions. This way, the focus is on the light - heartedness of the situation rather than anything inappropriate.
Writers can start by building up the situation gradually. For example, they can foreshadow the event that will lead to Lucy being naked and embarrassed. Then, focus on Lucy's reactions. Her shock, embarrassment, and attempts to cover up can be really engaging. Also, use the reactions of other characters in Fairy Tail. Their laughter, shock, or attempts to help can add depth to the story.
One idea could be Juvia getting caught in an embarrassing situation during a Fairy Tail mission. For example, she might accidentally use her water magic in a way that makes her clothes wet and she feels extremely self - conscious, leading to some comical and heart - warming interactions with the other guild members as they try to comfort her.
Perhaps Wendy could be under a spell that makes her think she's invisible but in reality she's not, and she unknowingly walks around naked in front of the Fairy Tail guild. This would cause great embarrassment for her. The story could then focus on how she discovers the truth and how the guild members react in a humorous yet supportive way.
Another plot could involve a spell gone wrong that causes Erza to be in a state of undress in a public area in the Fairy Tail world. She then has to deal with the embarrassment while also facing a new threat that has emerged during this chaos. The story could focus on her regaining her composure and dignity while solving the problem.
Juvia's character often develops through her relationships. For example, if she has a romantic relationship in the fanfiction, she might become more confident and assertive in expressing her feelings. She could also develop by facing her fears. If she's put in a dangerous situation, she might overcome her insecurities and grow as a mage.
To write a character - driven story in this context, focus on Mira's emotions. Show how her embarrassment affects her actions and decisions. For example, if she's naked and embarrassed, she might be more hesitant to be in the spotlight. Describe her internal thoughts, like how she's worried about what others in Fairy Tail think of her. This will make the story more about her as a character rather than just the embarrassing situation.
Her character could also be developed through her problem - solving skills. Since she's in an embarrassing naked state, she has to figure out how to get proper clothing and deal with the social implications. This forces her to think on her feet and use her wits. She might discover new magical abilities or ways of using her existing powers that she didn't know before. Maybe she can create a temporary magical covering using her swordsmanship skills and her latent magic powers, which shows her resourcefulness.
Wendy could start off as a very shy and self - conscious character due to the embarrassing situation. As the story progresses, she could gradually become more confident and assertive. For example, she might start by hiding from everyone in the guild, but then as she realizes her friends' support, she could start facing the situation head - on and even use it to her advantage in some situations, like when dealing with an enemy who tries to use her embarrassment against her.
