The Children of the Cold are the servants of the Cold Boy. They all agreed to become "numb" - which means that their bodies are technically dead. This makes them exceptionally hard to kill such that the only way to ensure that they are dead is decapitation. Due to the aura of coldness that surrounds them, fire is not considered a good method as it will just die out. They all live in the Winter Court except for when stalking new victims. However, since most of them are children (less than sixteen years old in most cases) they do like to come out and play.
Their eyes are black, though some of them can change them to look normal.
