One popular plotline is about the relationships between the characters. For example, exploring the relationship between Naruto and Hinata further, like their married life. Another could be adventures where all these characters team up against a new, powerful enemy that threatens the Hidden Leaf Village.
Some Naruto - related forums might also be a good place. The fans there are usually very enthusiastic about sharing and discussing fanfics. For example, Naruto Forums. You can post a thread asking for good fanfics about Naruto, Hinata, Sasuke, Sakura, Neji and Tenten, and I'm sure you'll get some great recommendations.
One great 'Naruto Hinata Sakura Sasuke Fanfic' is 'The Bonds Beyond'. It delves into the complex relationships between these characters. It shows how Hinata's quiet strength affects the group, and how Sakura's growth as a medic-nin plays a role in their adventures. Sasuke's journey back to the village and his interactions with Naruto are also well - explored in this fanfic.
One great fanfic with this premise might be 'Sakura's Unusual Bond' where the author explores the complex relationships that form when Sakura is engaged to both Neji and Sasuke. It delves into the emotional turmoil and how the three characters grow and change because of this situation.
A fanfic called 'Neji and Tenten: Unspoken Promises' is also quite good. It explores the unspoken bond between Neji and Tenten. It has some really touching moments where they support each other during tough times, and it also weaves in their individual character arcs really well within the story.
Love and relationships are also very common themes. The unrequited love that Sakura had for Sasuke for a long time, and Hinata's love for Naruto are often explored in different ways. Fanfics may show how these relationships develop and change as the characters mature.
Sakura could develop from being a somewhat self - conscious girl always trying to impress Sasuke to a confident ninja in her own right. Hinata might grow out of her extreme shyness and become more assertive, especially in her interactions with Naruto. Ino could develop her mental abilities further and learn to use them in more creative ways. Tenten might expand her weaponry knowledge and even invent new types of weapons.
Maybe a fanfic set in a modern - day AU (alternate universe). Sakura could be a doctor, Hinata a yoga instructor, Ino a florist, and Tenten a martial arts teacher. Their lives intersect in a small town, and they form a sort of girl - power group that helps each other out in different situations, like dealing with difficult customers or personal relationship problems.
Maybe a fanfic about a training camp they attend. Sakura and Ino might have a friendly rivalry during the training, while Tenten and Hinata help each other improve. They could learn new techniques from each other and also have some fun girl - time in between the intense training sessions.
Character development. A great fanfic about them will show how Tenten becomes a stronger kunoichi and how Neji overcomes his clan's limitations. For example, if the fanfic shows Tenten learning new jutsu and Neji breaking free from some of the Hyuga's traditional constraints, it stands out.
