Here you go:
You are also given a special Target Card! It includes the picture and all information about one of the players standing in this very room.
When you slide your Target Card over the dead target's collar, it will become ACTIVE. ACTIVE collars must, or at least should be, inserted in a Treasure Chest located on front of the school building, and you are rewarded for something that might help you... But be quick! There are only 5 Treasures, so only the first 5 will get their treasures." GM tells to everyone with a sadistic and a bit childish way, like he told it to some 6-year olds.
