Depending on the village leader's decisions, the missing-nin in question may be given leniency. The most prominent example is Sasuke Uchiha who is not marked for death by the Fifth Hokage, Tsunade as a favour to Naruto Uzumaki , and is instead to be brought back as a Konohagakure citizen. However, according to shinobi, a missing-nin is typically marked for death simply for defecting, and such mercy is rare. The Bingo Book contains information on every missing-nin and is given to every jonin and ANBU member by their respective Kage.
