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.
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.
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.
It depends on how one looks at it. If the 'embarrassed naked' aspect is used in a way that is more about exploring vulnerability in a non - sexualized way, it could potentially be an interesting take on the character. However, more often than not, this kind of description in fanfiction can cross the line into being disrespectful to the original character design and the values of the Fairy Tail series. So, overall, it's likely not appropriate.
The fanfiction could revolve around Yukino being embarrassed about a secret power she has that is related to her Fairy Tail identity. This power might have something to do with a form that makes her appear 'naked' in a sense, like a transformation that she's not fully in control of. She then has to learn to accept and master this power with the help of her friends in the guild.
One common theme could be Lucy's growth and self - discovery. In many fanfictions, even when she might be in an 'embarrassed' or vulnerable situation like being naked (in a non - vulgar, more like magically or accidentally exposed way), it can be a catalyst for her character development. For example, she might learn to be more assertive or gain a new understanding of her powers. Another theme could be the relationship dynamics within the Fairy Tail guild. Her embarrassment might bring out different reactions from her guildmates, highlighting the strong bonds and camaraderie in the guild. Also, some fanfictions may explore themes of love and romance, with her 'embarrassed' situation leading to a deeper connection with a particular character.
To develop Juvia's character further in fanfiction, you could focus on her emotional growth. For instance, have her face rejection from someone she cares about deeply. This would force her to reevaluate her self - worth and how she approaches relationships. You could also have her take on a mentorship role for a new, younger member in Fairy Tail. This would not only show her growth as a mage but also her ability to be nurturing and responsible. Another aspect could be exploring her creativity. Maybe she discovers a new way to use her water magic in an artistic or unconventional way, which could lead to new friendships and adventures within the Fairy Tail universe.
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.
Maybe in a fanfiction, Wendy is put under a spell that makes her think she's invisible but in reality, she's actually naked. She goes about her day in Fairy Tail, oblivious to her state, and gets into all sorts of embarrassing situations. For example, she might walk into a meeting of the guild leaders in that state. When she finally realizes, she's extremely mortified but her friends help her through it.
