Perhaps he uses some ninja techniques like a shadow clone jutsu. He could make multiple clones to help him sort through and complete the paperwork quickly.
In certain fanfictions, Naruto could approach the paperwork in a more diplomatic way. He might convince others in the village, like his friends or some of the ninja clans, to help him with the paperwork. By using his charisma and leadership skills, which he has developed over time, he gets everyone to pitch in. And with their combined efforts, they manage to defeat the mountain of paperwork. After all, Naruto is not just a powerful fighter but also a great leader who can inspire people to work together.
It depends on the specific fanfiction. Some might have Naruto develop strategies or skills to overcome the paperwork challenge. Others might not focus on this aspect at all.
The plot could center around Lucy's transformation as she does the guild paperwork. At first, she might be frustrated and overwhelmed, but as she delves deeper, she starts to understand the importance of it for the guild's functioning. She could also find some hidden secrets or messages in the paperwork that lead to an adventure.
Maybe Naruto discovers a hidden scroll that has a spell or technique specifically for dealing with paperwork. He then uses this new - found knowledge to make all the paperwork disappear or transform into something more manageable, like a single small scroll that contains all the important information in a condensed form.
Perhaps a perk is the ability to shape the future of the ninja world. As Hokage, one can inspire the younger generation of ninjas. They can create new ninja academies or training programs. They also have the power to pardon or punish ninjas according to their deeds, which helps in maintaining law and order in the village.
Sasuke could also be a possibility for the 6th Hokage in the fanfic. He has grown stronger over the years and his unique perspective on the ninja world could bring new ideas to the leadership of the Hidden Leaf. He might start off as a controversial choice but prove himself through his actions in protecting the village and making tough decisions.
Sasuke could be an alternative. He has strong ninja skills and a deep understanding of the ninja world. His experiences have made him grow into a very capable person, and his Sharingan gives him an edge in combat and strategic planning.
Their relationship would likely grow stronger. Naruto would gain more respect for Hiruzen as he sees the amount of work the old Hokage has to do. And Hiruzen would see Naruto's eagerness to help and grow. This could lead to Hiruzen giving Naruto more responsibilities within the village.
