As Beavis said, rares are, on average, 60 pulls, it could be 50-70, 80 at most (This only ever happened to me once in GNW, I'm assuming that this treasure's about the same though.), so it technically would be more pulls then Darui, but they each take about the same amount of time. While Darui could be pull 60, Danzo may be pull 120, I got my own Danzo 300 pulls in as my 5th rare. Some people get him later.
