Aka the Kimimaro arc. Because that's pretty much the bulk of this story line. Now for the platinum, I'm currently 94% finished with the mission log and have 89% of the trophies. All that's left is to complete the missions, and there has been so much to do. For a fighter, UNS is pretty loaded with side material. You pretty much need to complete most of the missions at least twice for the bonus conditions. Other than that, there are some combat related trophies that are no problem to complete. :) 33 hours in and not a single jutsu clash!
