For instance, he might be the one assigned to track down a particularly dangerous ninja on the Bingo Book list. His calm and collected demeanor in the face of danger would add an exciting element to the story.
Maybe it's a powerful enemy from outside the village who has infiltrated the bingo book system. They see Naruto as a major threat to their plans and so secretly added him to the book, so they can send their minions to take him out without raising too much suspicion.
Kakashi is another popular choice. His intelligence and combat skills are well - known. In 'naruto bingo book fanfic' stories, he could be a mentor figure helping others deal with the threats posed by the Bingo Book, or he could be a character with a mysterious past related to the people in the book.
Maybe it's a group of shinobi from a rival village. They see Naruto as a threat to their village's power and influence. With him in the Bingo Book, they think it's a legitimate chance to eliminate him and send a message to Konoha.
