But in 'hired assassin Naruto fanfic', the assassin's perspective and their unique skills and motives drive the story.
Sasuke could be a likely candidate in a sense. Given his skills as a ninja, his Sharingan which gives him an edge in combat and perception, and his past as a sort of 'rogue' ninja. He could be in a situation where Naruto has to hire him for a special mission that requires his unique abilities. Another possibility is Kakashi. He has a vast array of skills, is very intelligent, and could easily take on the role of an assassin if needed, even if it goes against his normal moral code slightly. He would do it for Naruto's sake.
Well, a plot could be that Naruto hires an assassin to eliminate a group of rogue ninjas who are targeting his friends. The assassin might be a former enemy who has a change of heart.

The assassin has special abilities that are crucial to the success of the mission.
