One idea for the main plot is that a group of rogue ninjas has developed a new and dangerous jutsu that can disrupt the balance of power in the ninja world. Naruto, in his role as Hokage, decides to take action. Sasuke, as an Anbu, is sent to infiltrate the group. As Sasuke gets closer to the truth, he finds that the leader of the rogue ninjas has a personal vendetta against Naruto. This forces Sasuke to race against time to stop the jutsu and protect Naruto and the village. Along the way, Sasuke also has to come to terms with his own past actions and how they might affect the current situation.
One possible scenario in such a fanfiction could be Naruto as Hokage having to deal with political situations in the village while Sasuke, as an Anbu, is sent on dangerous covert missions. Naruto might rely on Sasuke's intelligence and combat skills from his Anbu work to protect the village from external threats. They could also have some internal conflicts due to their different roles and the secrecy associated with Sasuke's Anbu work.
One idea could be Sasuke leading an Anbu mission while Naruto, as Hokage, has to deal with the political fallout of the mission's actions. For example, if the Anbu under Sasuke's command accidentally cross a border during a pursuit, Naruto has to smooth things over with the neighboring village.
One common theme is redemption. Sasuke, having had a troubled past, may find redemption through his work as an ANBU under Naruto's leadership as hokage. Another theme is friendship. Despite their past differences, they rekindle their friendship in many of these stories. Also, protection of the village is a big theme. Naruto as the hokage and Sasuke as an ANBU are both committed to safeguarding the village from all threats.
Their relationship would be one of mutual respect. Naruto, as Hokage, would trust Sasuke's abilities as an Anbu member. Sasuke, on the other hand, would respect Naruto's leadership. They would be comrades again, but with a new dynamic due to their different positions in the village.
One popular type of hokage naruto x anbu sasuke fanfiction often involves them teaming up on a dangerous mission. In these stories, Naruto, as the hokage, has to rely on Sasuke's skills as an ANBU member. They might start off a bit rough due to their past differences but gradually grow closer as they face various challenges together.

One idea could be Naruto and Sasuke teaming up to face a new, powerful and ancient threat that even the combined might of the Hidden Villages can't handle easily. They have to use their unique skills and the bond they've reforged as Hokage and his equal.
A great plot could be that there is a curse that starts to affect all the ninja in the village and only Naruto and Sasuke's combined chakra can break it. They must embark on a journey to find the source of the curse. Along the way, they discover secrets about the past Hokages and how to better lead the village. Or perhaps a plot where Sasuke, who has been away from the village for a long time, returns and is shocked to see Naruto's new Hokage - like leadership style. He decides to challenge Naruto not in a fight but in a contest of who can better protect and improve the village, leading to a series of events that show their different approaches.
Well, without having read the exact fanfiction, it might depict Sasuke and Sakura in the ANBU setting facing various challenges. It could explore how their skills as ANBU members are put to the test, and how their feelings for each other, whether it's friendship or something more, are affected by the high - stress and often secretive nature of ANBU work. They could be involved in undercover operations or battles against powerful enemies within the context of the ANBU.

The fanfiction could be about Naruto's struggle to adjust to a normal life after being Hokage. He might feel a bit lost without the constant stream of paperwork and decision - making. So, he starts to explore his hobbies, like fishing. Meanwhile, he still has to deal with some remnants of old enemies who are trying to take advantage of his retirement, and he has to use his skills and influence in a different way to protect Konoha.
