Most official Naruto media focuses on the battles, character development, and the overarching story of the ninja world. Fanfics that involve the 'Sexy Jutsu' in a lesbian context are likely to be a very niche and perhaps not very well - received by the general Naruto fan base as it can be seen as objectifying characters in a way that doesn't fit with the core values of the series.
I don't really recommend focusing on'sexy' Naruto fanfics as they often deviate from the original spirit of the series. However, if you're looking for well - written Naruto fanfics, ones that explore the relationships between characters in a more positive and in - character way are great. For example, fanfics that focus on the friendship between Naruto and his friends like Sasuke and Sakura.
You can start by looking at popular fanfic websites. Check the reviews and ratings. Usually, fanfics with high ratings that are described as 'adventure' or 'character - development' are good choices. For example, on Archive of Our Own, you can filter by tags to find Naruto fanfics that are more in line with the original series' values.
Hinata is another. Her shy yet determined nature in the original series can be accentuated in fanfics, and her relationship with Naruto might be developed in different and interesting ways that show her as an alluring character.
The main characters are obviously Naruto and Hinata. Naruto is a very energetic and determined ninja who has always strived to be recognized. Hinata is a shy yet strong - willed kunoichi with a deep love for Naruto.
Maybe some would try to use it as a way to show female empowerment in the Naruto world, but it's a very strange and inappropriate way to do so. The Naruto series has its own ways of showing strong female characters without having to rely on such fanfic themes. For example, characters like Tsunade are shown as powerful leaders and ninjas in the official story.
One possible plotline could be Naruto and Hinata going on an adventure together outside of the Hidden Leaf Village. They might face some new and unexpected enemies and have to rely on each other's skills to survive.
Sakura would be a likely character. She has a long - standing relationship with Naruto in the original series, so it's easy to imagine her in a harem scenario. Hinata is another one. Her deep admiration and love for Naruto in the official story make her a prime candidate. Then there's also Temari. She is a strong - willed and powerful female character, and her interactions with Naruto in the series could be developed further in a harem fanfic.
Some fanfics might have a theme of self - discovery for Naruto. With the harem around him, he gets to learn more about himself, his emotions, and what he really wants in life. The presence of multiple female characters with different personalities and backgrounds forces him to look inward. Also, there could be a theme of cultural exploration. Since the Naruto world has its own unique culture, the relationships in the harem fanfic can be used to explore different cultural aspects, like how relationships are viewed in different ninja clans.
I'm not sure specifically what 'bulchi sexy fanfic' is about as 'bulchi' is not a common or known term in general fanfic contexts. It could be a very specific or made - up concept within a particular community or someone's personal creation.
