A plot could revolve around Levy writing a fanfiction herself about an embarrassing naked situation within the Fairy Tail guild, but then the story somehow comes to life in a magical way. She has to deal with the chaos that ensues as her fictional scenario plays out in reality. This could also explore her creativity as a writer and how she copes with the unexpected consequences of her own creation.
One possible plot idea could be Levy getting caught in an embarrassing situation during a Fairy Tail mission. For example, she might accidentally lose her clothes due to a magical mishap while trying to solve a riddle in an ancient ruin. This could lead to her being very embarrassed but also relying on her friends' support to get through it.
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.
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.
It can show her vulnerability. Levy is usually seen as a smart and capable mage in Fairy Tail. But in an embarrassing naked situation, her confidence might be shaken, revealing her more vulnerable side. For instance, she may become shy and reserved, which is different from her normal assertive self when dealing with books and knowledge.
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.
One plot idea could be that Mira gets caught in an embarrassing situation during a Fairy Tail event. For example, she accidentally casts a spell wrong and her clothes disappear just as an important guest arrives. Another could be that she is forced to participate in a contest where she has to show a hidden talent, but she's embarrassed about it. Maybe she has to sing in front of everyone when she thinks she's a bad singer.
A plot idea could be that Cana is dared to do something embarrassing in the Fairy Tail guild hall as part of a bet. She's hesitant at first but her competitive side takes over. However, things don't go as planned and she ends up in an even more embarrassing situation. Or perhaps she discovers a hidden power within herself while in an embarrassing state. She could be naked in a magical realm where she has to overcome her embarrassment to harness this new power and return to the normal world. This could lead to her becoming a stronger member of Fairy Tail.
One plot idea could be that Kagura finds herself in an embarrassing situation in a magical forest. Maybe she loses her clothes due to a spell gone wrong. As she tries to find a way to get them back, she has to interact with various Fairy Tail characters, leading to humorous and heartwarming exchanges. For example, she might encounter Natsu who, in his typical clueless way, doesn't quite understand her distress at first but then tries to help.
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.
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.
