Well, without actually reading the specific 'naked boys story', it's hard to say exactly. But generally, it could be the boys themselves who are the main characters. They would be the ones driving the plot forward, facing whatever challenges or experiences the story has in store for them.
In the 'The Emperor's New Clothes' which is often associated with the 'naked king story', the main characters are the emperor, the two swindlers, and the child. The emperor is vain and easily deceived. The two swindlers are the ones who start the whole deception. And the child is the one who tells the truth about the emperor being naked.
The main characters in the story are the king and the little child. The king is vain and easily deceived, believing he is wearing magnificent clothes when he is actually naked. The child is innocent and fearless, and he is the one who has the courage to say that the king is naked.
I'm not entirely sure without reading it more in - depth, but it could be ordinary people like a shopkeeper, a taxi driver, or a student. They are often the ones who bring the real flavor to a story set in a city like this.
There might be some fanfictions exploring Naruto and Sakura's relationship in a non - inappropriate way. However, the description you provided sounds like it could potentially lead to adult - themed content. In the Naruto fanfiction world, there are many well - written stories that focus on their friendship, teamwork, and growth without any improper elements.
Since I'm not familiar with a specific work titled 'naked monster hunter stories', I can't say for sure if there are popular characters. But if it follows the general Monster Hunter concept, there could be characters who are known for their great hunting skills or unique personalities.
One possible plotline could be that Naruto accidentally gets into a situation where he's embarrassed and naked, like maybe a prank gone wrong during a festival in Konoha. Hinata, being the shy and kind-hearted person she is, tries to help him while blushing furiously. Another could be that they are on a mission together and Naruto is put in this state due to some enemy's jutsu, and Hinata has to protect his dignity while they figure out how to reverse the effect.
The main characters could be a group of friends who were on a boat trip and got shipwrecked. They might be from different backgrounds, like one could be a good fisherman which helps them get food, another might be good at building things and is in charge of making shelters.
To write it tastefully, focus on the emotions rather than the physical state. For example, Naruto's embarrassment can be used to show his vulnerability, and Hinata's reaction can be about her kindness and respect for him. Don't go into too much detail about the nakedness. Instead, use it as a catalyst for character development and relationship building between them.
One way is to focus on their emotional connection. Look for fanfiction that delves deep into how Hinata's feelings for Naruto developed and how Naruto came to realize his own feelings for her. For example, stories that explore their silent moments of understanding during battles or important events in the Naruto series.
