Disgaea 3: Absence of Justice

To get the trophy you need to kill “Prinny Pirates” in LOC (Land of Carnage) Item World - these are pirates who travel in a rural cart. Can be found in items of any rank. They appear at levels 92-99 during the first two turns; if during the first turn none of the existing pirates appeared, we skip the level. Approximately every 2-3 hours of continuous farming appear.
