Often, side characters like Kakashi in Sasuke and Sakura Shippuden fanfic can be really well - written too. He can act as a mentor or a guiding figure for their relationship, providing wisdom and sometimes a bit of humor as he watches their relationship develop.
Sakura is also a great character in fanfics. Writers can develop her from a girl with a crush to a strong and independent kunoichi. They can show her medical skills and how she uses them not only to heal physically but also to heal the emotional wounds of those around her, especially Sasuke.
One great 'Sasuke Sakura Shippuden Fanfic' is 'A New Beginning'. It shows a different take on their relationship post - Shippuden. The story delves deep into how they deal with the traumas of the past and try to build a future together. The characterizations are really well - done, staying true to their original personalities from the anime.
Ino. Since she is Sakura's friend, she can bring in some girl - talk moments. She could also be a bit jealous of Sakura's relationship with Sasuke at first, but then come to accept it and even help them out in some situations in the fanfic.
There are many great authors out there. One popular one might be someone who really captures the essence of Sasuke's brooding nature and Sakura's growth in the Shippuden series. They write in a way that makes the characters' emotions feel real. But it's really subjective as different people like different writing styles.
A good 'Sasuke Sakura Shippuden Fanfic' should have believable character development. Since we already know Sasuke and Sakura from the anime, any changes or growth in their characters should be in line with what we know about them. For example, Sasuke's brooding nature should still be there but perhaps softened a bit in a relationship with Sakura.
Some fanfics might have a plot where Sasuke and Sakura get transported to an alternate universe. In this universe, they are not ninjas but ordinary people. This forces them to rely on each other in different ways and they discover new aspects of their personalities and their relationship.
A really interesting fanfiction could be set in an alternate universe where Sasuke never left the village in Naruto Shippuden. He and Sakura start to develop feelings for each other much earlier. They go through all the challenges of being young ninjas together, and their relationship blossoms as they face various threats to the village side by side, and they eventually get married and have a family.
One great OC could be a female ninja named Aya. She is strong - willed, has amazing combat skills, and is not afraid to stand up to Sasuke. Her determination and loyalty make her an interesting character in the fanfiction. Another could be Kai, a male OC who has a unique ability to control the elements in a different way than the known ninja in the Naruto universe. His different perspective and skills make him stand out when paired with Sasuke.
One great Sasuke and Sakura fanfic is 'A New Beginning'. It shows a post - war scenario where Sasuke and Sakura are trying to rebuild their relationship. The author beautifully depicts Sakura's growth and her unwavering love for Sasuke. Another good one is 'Together Again' which focuses on their adventures as a couple, facing new threats in the ninja world. It has some really exciting fight scenes and tender moments between them.
One interesting fanfiction could be about Sasuke and Sakura going on a mission together in the Shippuden era. They might face a powerful new enemy and have to rely on their combined skills and their growing bond. Maybe Sasuke has to protect Sakura in a dangerous situation, which deepens their relationship further.
I really like 'The Team 7 Reunion Fanfic'. In this, Sakura has grown into a more powerful kunoichi. The story focuses on how Naruto and Sasuke's return to the village affects her. It's a great read as it beautifully portrays their individual growth and how they come together as a team again. It has some emotional moments that really tug at your heartstrings.
