The timing for Sasuke's story in Naruto Shippuden is quite fluid. It can be influenced by the need to develop other storylines and characters. So, it's hard to put an exact number on the time passed before his story kicks in.
Sasuke's story wraps up in the final arcs of Naruto Shippuden. It's a complex and emotional ending that ties up his character development and relationships.
Another theme is power and growth. The OC usually has some unique power or ability. Their interactions with Sasuke lead to both of them growing in terms of power. This could be in combat skills or in understanding the complex nature of the ninja world. For instance, they might face a powerful enemy together and in the process, both Sasuke and the OC become stronger and more well - rounded characters.
One great 'naruto shippuden sasuke x oc fanfiction' is 'The Uchiha's New Path' where the OC has a unique connection with Sasuke that changes his journey in interesting ways.
The First Hokage is obviously the main character. But we may also see other important figures like his contemporaries, who were also involved in the establishment of the Hidden Leaf Village.
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.
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.
We can expect to learn about the origin of the Hidden Leaf Village. The First Hokage played a crucial role in its foundation. His story might include how he developed the village's ninja system and his relationships with other powerful ninjas at that time.
In the end of Naruto Shippuden, there's a sense of closure as major conflicts are resolved. Naruto becomes a respected leader, and many characters find their places and happiness. The bonds among friends and the growth of characters are emphasized.
