In general, fanfiction that involves characters sneaking into a female bathhouse through transformation (henge) is inappropriate and goes against the respectful portrayal of characters. It often objectifies female characters and violates the boundaries of proper storytelling.
There are many great alternatives. For example, fanfiction about Naruto's training with new jutsus. He could be exploring a new type of chakra control or learning a secret technique from an old master. Another option is fanfiction focusing on the relationships between the characters, like how Naruto helps Sasuke fully return to the village and rebuild their friendship.
In a fanfiction, the female henge into a bikini - clad character might lead to some interesting character development. For example, Naruto could learn more about how female characters are perceived in the ninja world. His friends' reactions, like Sasuke being a bit flustered or Sakura being jealous of the 'new girl', could add depth to the story.
A simple story could be that Naruto accidentally uses the female henge in front of his friends while wearing a bikini - like getup. His friends are shocked at first but then burst into laughter. It could be a light - hearted, one - shot fanfiction.
One possible fanfiction idea could be Naruto using his henge technique to transform into someone wearing a really cool swimsuit. Maybe he does it for a mission at a beach resort where he has to blend in with the tourists. He could transform into a famous surfer and use his skills to gather information.
Well, it could be due to a disruption in the chakra control. If the character who performed the female henge loses focus or gets distracted, the chakra maintaining the transformation might falter and cause the henge to disappear. For example, if they are suddenly attacked or startled during the henge.
One possible fanfiction could be that Naruto henge into a swimsuit as a prank. He might transform into a ridiculous swimsuit -covered version of himself to make his friends laugh. For example, he could turn into a swimsuit with a huge fish pattern all over it and start acting like a goofy mermaid in front of Sasuke and Sakura, just to break the tense mood during a training session.
Most likely not. The combination of 'panties' in the title gives the impression that it could involve inappropriate or at least very juvenile and not - so - family - friendly content. Naruto is a popular franchise that is enjoyed by a wide range of ages, and such a fanfiction concept seems to deviate from the more positive and acceptable themes usually associated with the series.
It could also lead to a loss of trust. If they were using the female henge to gain someone's confidence, like in a diplomatic or social situation within the fanfiction, the sudden disappearance would make others question their motives and integrity.
Well, Naruto could learn more about empathy. By being in Inari's form, he experiences life from Inari's perspective. This might make him more sensitive to the feelings of others who are not as confident or strong as he is.
